网上找到压缩方法。
但是我想问AbsolutePaths是什么？
ZipOutputStream ComStream = new ZipOutputStream(File.Create("F://新建文件夹"));
为什么会报错？？？？
ZipOutputStream ComStream = new ZipOutputStream(File.Create("F://新建文件夹.zip")); 可以


[解决办法]
1、源代码文件里面有注释：
/// <summary>
/// 存放待压缩的文件的绝对路径
/// </summary>
private List<string> AbsolutePaths { set; get; }
2、ZipOutputStream ComStream = new ZipOutputStream(File.Create("F://新建文件夹"));
为什么会报错？？？？
我刚试过，并没有这个问题
