如何删除使用.NET一个Zip文件的目录？ [英] How can I delete a directory in a Zip file using .NET?

问题描述

我将如何删除一个.zip的目录和所有在里面（最好使用DotNetZip）的文件？

How would I delete a directory in a .zip and all the files in it (preferably using DotNetZip)?

现在，我通过所有的文件运行在压缩，但它不工作：

Right now I'm running through all the files in the zip, but it doesn't work:

foreach (ZipEntry e in zip)
{
    //If the file is in the directory I want to delete
    if(e.FileName.Substring(0, 9) == "FolderName/")
    {
        zip.RemoveEntry(e.FileName);                          
    }
}

有没有更好的办法，如果不是，怎么会我做这项工作？

Is there a better way, if not, how would I make this work?

推荐答案

第一因子评分。不要循环用foreach，而从集合中移除元素。结果
我会尝试这种方式。

First tought. Don't loop with foreach while removing elements from the collection.
I will try in this way

for(int x = zip.Count -1; x >= 0; x--) 
{ 
    ZipEntry e = zip[x];
    if(e.FileName.Substring(0, 9) == "FolderName/") 
        zip.RemoveEntry(e.FileName);                           
} 

不过，看着zip文件类的方法，我注意到的方法：
SelectEntries返回一个ICollection的。所以，我认为这是可能做到：结果
编辑：使用重载版本SelectEntries（字符串，字符串）

However, looking at the methods of the ZipFile class, I noticed the method: SelectEntries that return a ICollection. So I think it's possible to do:
Use overloaded version SelectEntries(string,string)

var selection = zip1.SelectEntries("*.*", "FolderName");
for(x = selection.Count - 1; x >= 0; x--)
{
    ZipEntry e = selection[x];
    zip.RemoveEntry(e.FileName);                           
}

在zip文件取消对所有项目的环

removing the loop on all entries in the zipfile
