本文提供了使用 C# 和 VB.NET 实现的消息框示例代码，展示了如何通过调用 Windows API 的 MessageBox 函数来创建标准的消息对话框。

VB.NET:

Imports System.Runtime.InteropServices
Public Class MessageBoxVB
    Public Const UserReference As String = "user32.dll"
    <DllImport(UserReference)> _
    Private Shared Function MessageBox(ByVal hWnd As IntPtr, ByVal pText As String, ByVal pCaption As String, ByVal uType As Int32) As Int32
    End Function
End Class

C#:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;

namespace ComVisibleCS
{
    class MessageBoxCS
    {
        public const String UserReference = "user32.dll";
        [DllImport(UserReference, SetLastError = true)]
        private static extern Int32 MessageBox(IntPtr hWnd, String pText, String pCaption, Int32 uType);
    }
}
