怎么用C#读取文本文件，然后写进excl文件？

怎么用C#读取文本文件，然后写进excl文件？ 有懂得吗？我是小白 不懂

C#中得winfrom项目，如何导入excl文本，并且可以获取数据的数量，最后可以进行打印或则导出

我要做的是一个摇奖的程序，导入excl文本，并且能获取数据的数据数量，最后导出或则是打印的技术代码，大神们，求助呀！

如何用POI 读取excl模板,然后通过数据库写入大量数据 ，创建多个sheet，求解决！！！

 根据记录数，自动分工作簿，每个工作簿11条记录

用java实现：上传excl表格。读取数据，输出结果。

package chexianchaxun; import java.io.*; public class FeiYong{ public static void main(String[] args) throws Exception { java.net.URL url = new java.net.URL("http://********"); java.net.URLConnection con = url.openConnection(); con.setUseCaches(false); con.setDoOutput(true); con.setDoInput(true); DataOutputStream dataOut = new DataOutputStream(con.getOutputStream()); //字节流：InputStream(读取)、OutputStream(写入) String Msg = "<Request> <VinNo>ZAMJK39E6B0060491</VinNo><LicenseNo></LicenseNo><LoginID>215288</LoginID></Request>" ; /**转保车辆VinNo为必填 */ System.out.println(Msg); //字符流：Writer(写入)、Reader(读取) dataOut.write(Msg.getBytes("gbk"));//将已经解析出来的字节数据转化为gbk编码格式的字符串 dataOut.flush(); dataOut.close(); InputStream is = con.getInputStream(); InputStreamReader isr = new InputStreamReader(is, "gbk"); BufferedReader br = new BufferedReader(isr); StringBuffer sb = new StringBuffer(); String templine=null; while ((templine = br.readLine()) != null) sb.append(templine); System.out.println(sb.toString()); } } 如上。 当个输入信息车架号，通过接口，可以获取对应的数据信息。 现需要实现，excl表格形式上传，表格内有多条车辆的车架号数据，通过接口，然后再获取对应的数据信息。 感谢Always_MyLoverX 的耐心回答

Linux中用C的msgget()不使用IPC_EXCL也返回EEXIST错误

Linux中用C的msgget()不使用IPC_EXCL也返回EEXIST错误，网上都说不使用IPC_EXCL，光使用IPC_CREAT会返回msgid或创建一个新的队列， 但是，在我的程序里面，并！没！有！ 求助大神们帮我看看怎么回事的！ 我是在centos6.5中运行的，用的GCC编译 这个是运行的结果:  这个是代码： ``` #include <stdio.h> #include <sys/types.h> #include <sys/ipc.h> #include <sys/msg.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include <time.h> #include <errno.h> void msg_show_attr(int msg_id, struct msqid_ds msg_info){ int ret = -1; sleep(1); ret = msgctl(msg_id, IPC_STAT, &msg_info); if(ret == -1){ printf("failed to get msg info!\n"); return; } printf("--------now print info:---------\n"); printf("队列中字节数：%ld\n", msg_info.msg_cbytes); printf("队列中消息数：%d\n", (int)msg_info.msg_qnum); printf("队列中最大字节数：%d\n", (int)msg_info.msg_qbytes); printf("最后发送(接收)消息的进程：%d(%d)\n", msg_info.msg_lspid, msg_info.msg_lrpid); printf("最后发送(接收)消息的时间：%s(%s)\n", ctime(&(msg_info.msg_stime)), ctime(&(msg_info.msg_rtime))); printf("最后变化的时间：%s\n", ctime(&(msg_info.msg_ctime))); printf("消息UID=%d, GID=%d\n", msg_info.msg_perm.uid, msg_info.msg_perm.gid); } int main(){ int ret = -1; int msg_flags, msg_id; key_t key; struct msgmbuf{ int mtype; char mtext[10]; }; struct msgmbuf msg_mbuf; struct msqid_ds msg_info; int msg_sflags, msg_rflags; char *msgpath = "/ipc/msg"; //键值构建函数，获取IPC键值。 key = ftok(msgpath, 'c'); if(key == -1){ printf("ftok failed: %d!\n", errno); return -1; } printf("ftok succeed: %d!\n", key); //msgget()用来创建或者获取消息队列, msg_flags = 0; msg_flags |= IPC_CREAT; msg_flags |= IPC_EXCL; msg_id = msgget(key, msg_flags|0x0666); printf("msg flag is %d\nmsgget return: %d\n", msg_flags, msg_id); if(msg_id == -1){ printf("msgget failed: %s!\n", strerror(errno)); return -1; } printf("msgget succeed: %d!\n", msg_id); msg_show_attr(msg_id, msg_info); //开始发送消息 //并且此处设置为了IPC_NOWAIT，因此不会等待消息发送成功！即为异步执行！ msg_sflags = IPC_NOWAIT; msg_mbuf.mtype = 10; memcpy(msg_mbuf.mtext, "测试消息", sizeof("测试消息")); ret = msgsnd(msg_id, &msg_mbuf, sizeof("测试消息"), msg_sflags); if(ret == -1){ printf("msgsnd failed!\n"); }else{ printf("msgsnd succeed!\n"); } msg_show_attr(msg_id, msg_info); //开始接收消息 struct msgmbuf msgmbuf_r; msg_rflags = IPC_NOWAIT|MSG_NOERROR; ret = msgrcv(msg_id, &msgmbuf_r, 10, 10, msg_rflags);//成功返回接收的数据长度 if(ret == -1){ printf("msgrcv failed: %d!\n", errno); }else{ printf("msgrcv succeed, msg length: %d.\n", ret); } msg_show_attr(msg_id, msg_info); return 0; } ``` 还有图片版的代码：

关于linux中truncate函数的问题。

为什么我使用ftruncate截断文件后文件大小确实改变了，但是用read读取文件的内容还是截断之前的呢？ ``` int main(void) { //创建文件 int new_fd = open("file/a",O_RDWR|O_CREAT|O_EXCL,0644); if(-1==new_fd) { printf("%d: ",__LINE__-3); perror("creat"); exit(-1); } //打开文件 int old_fd = open("file/file_test",O_RDWR); if(-1==old_fd) { printf("%d: ",__LINE__-3); perror("open"); exit(-1); } //复制文件 char buff[1024]; while(read(old_fd,buff,sizeof(buff))) { int res = write(new_fd,buff,strlen(buff)); if(-1==res) { printf("%d: ",__LINE__-3); perror("write"); close(new_fd); close(old_fd); exit(-1); } memset(buff,sizeof(buff),0); } memset(buff,sizeof(buff),0); close(old_fd); //读出修改后的文件 lseek(new_fd,0,SEEK_SET); while(read(new_fd,buff,sizeof(buff))) { printf("%s",buff); memset(buff,sizeof(buff),0); } printf("\n\n"); //获得修改过后的文件的信息 struct stat st; if(-1==fstat(new_fd,&st)) { printf("%d: ",__LINE__-3); perror("stat"); close(new_fd); exit(-1); } printf("文件大小为%d\n",st.st_size); printf("文件最后修改时间为%s",ctime(&st.st_mtime)); printf("文件权限为%o\n\n",st.st_mode&0777); //截取前100个字节 if(-1==ftruncate(new_fd,100)) { printf("%d: ",__LINE__-3); perror("truncate"); close(new_fd); exit(-1); } close(new_fd); //先关闭文件描述符 new_fd = open("file/a",O_RDWR);//再次打开 if(-1==new_fd) { printf("%d: ",__LINE__-3); perror("creat"); exit(-1); } #ifdef DE if(-1==fstat(new_fd,&st)) { printf("%d: ",__LINE__-3); perror("stat"); close(new_fd); exit(-1); } printf("文件大小为%d\n",st.st_size); printf("文件最后修改时间为%s",ctime(&st.st_mtime)); printf("文件权限为%o\n\n",st.st_mode&0777); #endif //读出文件 memset(buff,sizeof(buff),0); lseek(new_fd,0,SEEK_SET); while(read(new_fd,buff,sizeof(buff))) { printf("%s",buff); memset(buff,sizeof(buff),0); } printf("\n\n"); //改变新建文件的权限 close(new_fd); remove("file/4_file"); return 0; } ```

关于HOOK word程序内部函数实现，解密的问题

我有一个word的加密文件，从一个工具里把这个加密文件解密后显示出来。目前可以 实现的是对于docx,pptx,excl,txt的文件格式都可以成功了，但是对于doc这一类的office 2003 的程序生成出来的加密，无法读取。图1 是我工具正常读取到的docx的解密文件，图2是 我读取doc文件后出现的结果，没东西显示出来，图3是我读取正常没有加密的doc的log， 图4的是我读取加密doc文件的log，两边的log就是从图中这个位置开始不一样了 现在就是找不到原因在哪里，不知道怎么改可以正常读取这个doc文件了

建一个窗体，获取选择的文件路径和输入框中的ID，传输给查询程序。

 效果如图。 点击上传按钮，能够选择本机的excl文件。获取路径。 输入框中输入数字ID 然后点击查询。（如果ID没有，或者文件路径没有，提示需要输入ID，或者需要选择文件） 点查询后，能够将ID和路径传给查询java。 查询的java已经写好了。 现在需要的是怎么建立这个窗体，来实现功能。 下面是窗体代码（需要修改的，我只是实现了界面排版）： package test; import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.*; import javax.swing.filechooser.FileNameExtensionFilter; import excel.ExcelOperate; public class AbsolutePosition extends JFrame implements ActionListener { private JButton b1;

// 绝对定位窗体的位置与大小 Container c = getContentPane(); // 创建容器对象 Label lb1 = new Label ("选择文件:"); b1 = new JButton("点击选择"); // 创建按钮 b1.addActionListener(this);//b1这个实例（按钮等）添加事件监听接口，this表示当前类的对象，在一个类里，你不需要new他的实例就直接可以用this调用它的方法和属性 area = new JTextArea(); pane = new JScrollPane(area); Label lb2 = new Label ("员工ID："); JButton b2 = new JButton("查询"); // 创建按钮 JTextField jt=new JTextField();//创建输入框 lb1.setBounds(30, 30, 120, 30); // 设置文本的位置与大小 lb2.setBounds(30, 80, 120, 30); b1.setBounds(140, 30, 120, 30); // 设置按钮的位置与大小 jt.setBounds(140, 80, 100, 30);//设置文本框位置和大小 b2.setBounds(140, 150, 100, 30); c.add(b1); // 将按钮添加到容器中 this.add(pane); c.add(b2); c.add(lb1); c.add(jt); c.add(lb2); setVisible(true); // 使窗体可见 // 设置窗体关闭方式 setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); } // 按钮事件 public void actionPerformed(ActionEvent e) { JFileChooser chooser = new JFileChooser();// 文件选择对话框 chooser.setAcceptAllFileFilterUsed(false);// 取消所有文件过滤项 chooser.setFileFilter(new FileNameExtensionFilter("Excel文件", "xls"));// 设置只过滤扩展名为.xls的Excel文件 //String firstNum = jt.getText();//获取输入框值 int i = chooser.showOpenDialog(this);// 打开窗口 if (i == JFileChooser.APPROVE_OPTION) { this.setLocation(0, 0);

程序员接私活怎样防止做完了不给钱？

首先跟大家说明一点，我们做 IT 类的外包开发，是非标品开发，所以很有可能在开发过程中会有这样那样的需求修改，而这种需求修改很容易造成扯皮，进而影响到费用支付，甚至出现做完了项目收不到钱的情况。 那么，怎么保证自己的薪酬安全呢？ 我们在开工前，一定要做好一些证据方面的准备（也就是“讨薪”的理论依据），这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发

Python十大装B语法

Python 是一种代表简单思想的语言，其语法相对简单，很容易上手。不过，如果就此小视 Python 语法的精妙和深邃，那就大错特错了。本文精心筛选了最能展现 Python 语法之精妙的十个知识点，并附上详细的实例代码。如能在实战中融会贯通、灵活使用，必将使代码更为精炼、高效，同时也会极大提升代码B格，使之看上去更老练，读起来更优雅。 1. for - else 什么？不是 if 和 else 才

通俗易懂地给女朋友讲：线程池的内部原理

餐厅的约会 餐盘在灯光的照耀下格外晶莹洁白，女朋友拿起红酒杯轻轻地抿了一小口，对我说：“经常听你说线程池，到底线程池到底是个什么原理？”我楞了一下，心里想女朋友今天是怎么了，怎么突然问出这么专业的问题，但做为一个专业人士在女朋友面前也不能露怯啊，想了一下便说：“我先给你讲讲我前同事老王的故事吧！” 大龄程序员老王 老王是一个已经北漂十多年的程序员，岁数大了，加班加不动了，升迁也无望，于是拿着手里

JDK12 Collectors.teeing 你真的需要了解一下

前言 在 Java 12 里面有个非常好用但在官方 JEP 没有公布的功能，因为它只是 Collector 中的一个小改动，它的作用是 merge 两个 collector 的结果，这句话显得很抽象，老规矩，我们先来看个图(这真是一个不和谐的图????): 管道改造经常会用这个小东西，通常我们叫它「三通」，它的主要作用就是将 downstream1 和 downstre...

为啥国人偏爱Mybatis，而老外喜欢Hibernate/JPA呢？

关于SQL和ORM的争论，永远都不会终止，我也一直在思考这个问题。昨天又跟群里的小伙伴进行了一番讨论，感触还是有一些，于是就有了今天这篇文。 声明：本文不会下关于Mybatis和JPA两个持久层框架哪个更好这样的结论。只是摆事实，讲道理，所以，请各位看官勿喷。 一、事件起因 关于Mybatis和JPA孰优孰劣的问题，争论已经很多年了。一直也没有结论，毕竟每个人的喜好和习惯是大不相同的。我也看
