消息框传递选择C＃ [英] Message box pass selection C#

问题描述

尝试检查课本是空的。如果是，请向用户显示是，否的消息框，并取消询问是否选择默认代码。如果用户舔是，请将邮政编码传递到文本框。



我尝试过：

Trying to check textbook is empty. If so, show the user a message box with Yes, No and cancel asking if to chose default code. If user lick yes, pass zip code to the text box.

What I have tried:

private void Submit_Click(object sender, EventArgs e)
{

    if (PostalCodeTextBox.Text == "")
    {

        DialogResult result1 = MessageBox.Show("Please Enter zip code, or chose yes to select default zip code", MessageBoxButtons.YesNoCancel); 
    }
    else
    {
        PostalCodeTextBox.Text = "44844";
    }

推荐答案

Sooo ......问题是......？



看起来你没有检查那个DialogResult的值，所以在将任何内容放入TextBox之前你可能想要这样做。

Sooo... the question would be ....?

It looks like you're not checking the value of that DialogResult so you might want to do that before putting anything in the TextBox.
