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
