急，大神帮忙，VS2005 串口接收字符串换行问题！

Question

void comm_DataReceived(object sender,SerialDataReceivedEventArgs e)
{
int n =0;
n = comm.BytesToRead;
byte[] buf = new byte[n];
received_count += n;
comm.Read(buf,0,n);
builder.Remove(0, builder.Length);

this.Invoke((EventHandler)(delegate
this.Rtxt_box.AppendText(builder.ToString());

this.Rtxt_box.AppendText(Environment.NewLine);
}
));
};
等到的结果却是,我想要达到这个效果
把his.Rtxt_box.AppendText(builder.ToString()+"\n");效果还是一样的

Answer 1

你并不是每次都收到一行

this.Rtxt_box.AppendText(Environment.NewLine);
这个去掉
