在C#中利用WMI从快捷方式中复制目标文件

在C#中利用WMI从快捷方式中复制目标文件

电子信箱：ThreeTorches@163.com

前一段时间，因为单位要做几个展板，领导在做的时候误将快捷方式文件当成了目标文件，在进行文件拷贝时才发现文件的大小不对。此时所有选用的图片文件都被用在了快捷方式上，这些文件有几百个之多，通过查看快捷方式得到目标文件，并将目标文件的主名改成快捷方式的主名，扩展名不变。一个一个做，又要大半天的时间。同事求助于我，我考虑了一下，便用C#和WMI写了一个程序，希望能帮助遇到类似问题的人。
主要用到命名空间System.Management和WMI中的Win32_ShortcutFile类及其四个属性：

属性	说明
Name	获取快捷方式文件的完整路径名及文件名
Target,	获取快捷方式文件的所指向的目标文件的完整路径名及文件名
Drive	快捷方式文件所在的盘符，如C:
Path	快捷方式文件所在的路径，不包括盘符前后均有“/”，如/user/sub/，在具体应用时要注意，在WMI中“/”是转义字符，所以在传递时要用“//”。

在VS.NET新建一个工程CopyFromShortcut，将Form1.cs改名为“CopyFile.cs”,并在项目菜单中添加对System.Management的引用。最终运行图如下：

具体文件代码如下：
CopyFile.Designer.cs：
namespace CopyFromShortcut
{
partial class CopyFile
{
/// <summary>
/// 必需的设计器变量。
/// </summary>
private System.ComponentModel.IContainer components = null;

/// <summary>
/// 清理所有正在使用的资源。
/// </summary>
/// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
