如何在 .NET 中显示错误和警告消息框/如何自定义消息框

Question

Using C# .NET (Winforms).

I want to know how can I show the message boxes with a Ding!! sound & a red colored cross mark in it. This is what I'm talking about:

How to do such things for my software, with custom errors and custom warnings?

MessageBox.Show("asdf");

doesn't give me customize.

    MessageBoxButtons.OK, 
    MessageBoxIcon.Warning // for Warning  
    //MessageBoxIcon.Error // for Error 
    //MessageBoxIcon.Information  // for Information
    //MessageBoxIcon.Question // for Question
   );

MessageBox.Show(
  "your message",

Answer 4

You should add namespace if you are not using it:

System.Windows.Forms.MessageBox.Show("Some text", "Some title", 
    System.Windows.Forms.MessageBoxButtons.OK, 
    System.Windows.Forms.MessageBoxIcon.Error);

Alternatively, you can add at the begining of your file:

using System.Windows.Forms

and then use (as stated in previous answers):

MessageBox.Show("Some text", "Some title", 
    MessageBoxButtons.OK, MessageBoxIcon.Error);

        DialogResult result = MessageBox.Show("Are you sure you want to exit?", 
        "", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Question);
        if (result == DialogResult.Yes)
        {
            Application.Exit();
        }
