成功了、知道是那里的原因了、另附上源代码
static void Main(string[] args)
{
Bank bank = new Bank();
bank.CreateAccount();
bank.Create();
}
public class User {
public string Name;//定义姓名
public string PassWord;//定义密码
public string IdentityNum;//定义身份证
public double balance;//定义存款余额
public string Account;//定义帐号
public double yue;//定义余额
public double qujin;//定义取款金额
public void quxian() {
if (qujin > 0) {
if (qujin < balance)
{
yue = balance - qujin;
Console.WriteLine("取款成功！ 当前余额为：{0}", yue);
}
else {
Console.WriteLine("您输入的金额错误！");
}
}
else{
Console.WriteLine("您输入的金额需要大于0");
}
}
}
public class Bank {
User user = new User();
public void CreateAccount() {
Console.WriteLine("请输入账户姓名：");
user.Name = Console.ReadLine();
user.Account = "179708064356";
Console.WriteLine("请输入账户密码");
user.PassWord = Console.ReadLine();
Console.WriteLine("请输入账户身份证号码：");
user.IdentityNum = Console.ReadLine();
Console.WriteLine("请输入存款金额：");
user.balance = double.Parse(Console.ReadLine());
Console.WriteLine("账户信息：{0},姓名：{1},存款金额：{2} 创建成功！", user.Account, user.Name, user.balance);
Console.ReadLine();
}
public void Create() {
Console.WriteLine("请输入账户姓名：");
user.Name = Console.ReadLine();
if (user.Name == "179708064356")
{
Console.WriteLine("请输入账户密码：");
user.PassWord = Console.ReadLine();
if (user.PassWord == "1234")
{
Console.WriteLine("请输入取款金额：");
user.qujin = double.Parse(Console.ReadLine());
user.quxian();
Console.ReadLine();
}
else
{
Console.WriteLine("密码卟正确！");
}
}
else
{
Console.WriteLine("账户卟正确！");
}
}
}
