所以我的程序运行良好，但每当我在表格2上注册时，它说它找不到路径我不知道什么是错的请帮助我需要稍后传递它，我不知道我是否需要制作C上的新文件夹：只是为了获取LOGIN.ID
{public partial class Form1：Form {public string username，password; public Form1（）{InitializeComponent（）; }
private void button2_Click(object sender, EventArgs e)
{
Form2 form2 = new Form2();
form2.Show();
}
private void button1_Click(object sender, EventArgs e)
{
try
{
var sr = new System.IO.StreamReader("C\\" + textBox1.Text + "\\login.ID");
username = sr.ReadLine();
password = sr.ReadLine();
sr.Close();
if (username == textBox1.Text && password == textBox2.Text)
MessageBox.Show("Log-in Successfull", "Success!");
else
MessageBox.Show("Username or password is wrong! ","Error!");
}
catch (System.IO.DirectoryNotFoundException )
{
MessageBox.Show("The user doesn't exist!", "Error!");
}
}
}
}
//表格2
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
private void button2_Click(object sender, EventArgs e)
{
Form2 form2 = new Form2();
form2.Hide();
}
private void button1_Click(object sender, EventArgs e)
{
try
{
var sw = new System.IO.StreamWriter ("C\\" + textBox1.Text + "\\login.ID");
sw.Write(textBox1.Text + "\n" + textBox2.Text);
sw.Close();
}
catch(System.IO.DriveNotFoundException )
{
System.IO.Directory.CreateDirectory("C:\\" + textBox1.Text);
var sw = new System.IO.StreamWriter("C\\" + textBox1.Text + "\\login.ID");
sw.Write(textBox1.Text + "\n" + textBox2.Text);
sw.Close();
}
}
}
}

您在代码中的许多地方错过了
C驱动器之后的:改成
你应该仔细看看你的路径 . 我不认为c \存在 . 可能你正在使用C：\如果你仍然有问题，可能你的TextBox1.Text返回一个错误的路径 .
