C#压缩文件夹至zip，不包含所选文件夹【转+修改】
转自园友：jimcsharp的博文C#实现Zip压缩解压实例【转】
在此基础上，对其中的压缩文件夹方法略作修正，并增加是否对父文件夹进行压缩的方法。（因为笔者有只压缩文件夹下的所有文件，却不想将选中的文件夹打入压缩文件的需求），话不多说，上代码：
其中需要依赖ICSharpCode.SharpZipLib.dll:
之后，新建一个类，代码如下：

压缩文件夹，是否包含父文件夹，调用：
public static bool ZipDirectory(string folderToZip, string zipedFile, Boolean IncludeParent)
解压缩功能我也将原方法注释了，重新找了一个方法，因为原方法在将.xml文件解压出来的时候，会在末尾加入一堆NULNULNULNUL.......，大家可以自己去尝试下。
