推荐答案

public static void Main(string[] args) {
    // Starts the application.
    Application.Run(new Form1());
 }
 protected void button1_Click(object sender, System.EventArgs e) {
    // Populates a list box with three numbers.
    int i = 3;
    for(int j=1; j<=i; j++) {
       listBox1.Items.Add(j);
    }
    /* Determines whether the user wants to exit the application.
     * If not, adds another number to the list box. */
    while (MessageBox.Show("Exit application?", "", MessageBoxButtons.YesNo) ==
       DialogResult.No) {
       // Increments the counter ands add the number to the list box.
       i++;
       listBox1.Items.Add(i);
    }
    // The user wants to exit the application. Close everything down.
    Application.Exit();
 }

您正在开发Web应用程序还是Windows应用程序?

如果是Windows，请使用以下命令:

Are you developing web application or windows application?

If windows, then use this:

MessageBox.Show("Your Message","Your Caption", MessageBoxButtons.YesNo, MessageBoxIcon.Question);

如果是Web应用程序，则需要编写Javascript来显示消息框.

If web application, you need to write javascripts for displaying messagebox.
