由于基础比较差，麻烦详细点，谢谢，这是我之前提问的后面，字数有限，只能分开
protected bool exist()
//判断用户名密码是否正确
{
string str = "";
FileStream fs = new FileStream(@"\Application\user.txt", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
StreamReader users = new StreamReader(fs);
string[] strings = null;
string id = null;
string name = null;
string pwd = null;
int sign = 0;
while ((str = users.ReadLine()) != null)
{
strings = str.Split(',');
id = strings[0].ToString();
name = strings[1].ToString();
pwd = strings[2].ToString();
if (this.txtName.Text.Trim() == id && this.txtPwd.Text == pwd)
{
loginInfo.userId = id;
loginInfo.pwd = pwd;
loginInfo.userName = name;
sign=1;
break;
}
else
{
sign=0;
}
}
users.Close();
fs.Close();
if (sign == 1)
{
return true;
}
else
{
return false;
}
}
protected void existUser()
{
string str = "";
FileStream fs = new FileStream(@"\Application\user.txt", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
StreamReader users = new StreamReader(fs);
string[] strings = null;
string id = null;
string name = null;
while ((str = users.ReadLine()) != null)
{
strings = str.Split(',');
id = strings[0].ToString();
name = strings[1].ToString();
if (this.txtName.Text.Trim() == id)
{
users.Close();
this.labId.Text =name;
break;
}
}
}
private void txtName_TextChanged(object sender, EventArgs e) //数据验证
{
this.labId.Text = this.txtName.Text.Trim();
if (!Regex.IsMatch(this.txtName.Text.Trim(), @"^\d{0,100}$"))
{
MessageBox.Show("输入格式错误！");
this.txtName.Text="";
}
}
private void timer1_Tick(object sender, EventArgs e)
{
this.lbSystemTime.Text = System.DateTime.Now.ToString();
}
}
}
还是有些不明白的，protected bool exist()
protected void existUser() private void txtName_TextChanged(object sender, EventArgs e)
实现什么功能里面有些语句也不懂，最好给个全篇的注释，谢谢啦，小弟基础差，麻烦各位了
