在自己的应用程序中显示Windows关于对话框

和在VB等语言中实现方式一样，调用Windows API.

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace Jacky.Win32API {
    /**//// <summary>
    /// Show Windows About Box
    /// </summary>
    public class AboutBox {
        [DllImport("shell32.dll")]
        private static extern long ShellAbout(int hWnd, string szApp, string szOtherStuff, int hIcon);

        private string _Title = Application.ProductName;
        private int   _FormHandle = 0;
        private int   _IconHandle = 0;
        private string _Version   = Application.ProductVersion;

        /**//// <summary>
        /// 
        /// </summary>
        /// <param name="FormHandle"></param>
        /// <param name="IconHandle"></param>
        /// <param name="Title"></param>
        /// <param name="Version"></param>
        /// <example>new AboutBox(this.Handle.ToInt32(), this.Icon.Handle.ToInt32(), "软件名称", "版本号Version 1.0").Show();</example>
        public AboutBox(int FormHandle, int IconHandle, string Title, string Version) {
            this._FormHandle = FormHandle;
            this._IconHandle = IconHandle;
            this._Title         = Title;
            this._Version     = Version;
        }

        /**//// <summary>
        /// 
        /// </summary>
        /// <param name="FormHandle"></param>
        /// <param name="IconHandle"></param>
        /// <example>new AboutBox(this.Handle.ToInt32(), this.Icon.Handle.ToInt32(), "软件名称", "版本号Version 1.0").Show();</example>
        public AboutBox(int FormHandle, int IconHandle) {
            this._FormHandle = FormHandle;
            this._IconHandle = IconHandle;
        }

        public long Show(){
            return ShellAbout(this._FormHandle, this._Title, this._Version, this._IconHandle);
        }
    }
}

调用方式：

new AboutBox(this.Handle.ToInt32(), this.Icon.Handle.ToInt32(), "软件名称", "版本号Version 1.0").Show();
