設置表單的密碼

Question

我試圖設置一個表單的密碼，並用標籤，文本框和確定按鈕創建了一個新表單，但是當我在文本框中輸入密碼時，它說密碼正確時密碼不正確。問題是什麼？

public partial class Password : Form 
{ 
    private string password; 
    public Password() 
    { 
     InitializeComponent(); 
    } 

    private void pass_TextChanged(object sender, EventArgs e) 
    { 
     string password = "mypass"; 
    } 

    private void okButton_Click(object sender, EventArgs e) 
    { 
     if (passtextBox.Text == password) 
     { 
      list form = new list(); 
      form.Show(); 
     } 
     else 
     { 
      MessageBox.Show("Incorrect Password. Try Again!!"); 
     } 
    }  
} 

Answer 1

問題是這是創建一個局部變量字符串。

private void pass_TextChanged(object sender, EventArgs e) 
{ 
    string password = "mypass"; 
} 

反而這麼做。

private void pass_TextChanged(object sender, EventArgs e) 
{ 
    password = "mypass"; 
}
