[C#] FileZip类|即使文件已经存在也提取. [英] [C#] FileZip class | Extract even if file already exist.

问题描述

即使文件已经存在，也可以使用FileZip类提取文件吗? atm我解压缩我的zip文件时出现错误，提示该文件已存在.

 ZipFile.ExtractToDirectory(Application.StartupPath +  @" ，Application.StartupPath);
File.Delete(Application.StartupPath +  @" ); 

解决方案

如果库中没有"overwrite existing"标志，那么首先要检查并删除它.

尝试执行以下操作:

 ZipArchive zipArchive = 新 ZipFile.OpenRead(Application.StartupPath +  @"  \ patch001.zip")；
 foreach (ZipArchiveEntry条目 in  zipArchive.Entries中)
{
      entry.ExtractToFile(Application.StartupPath + entry.Name， true );
}
zipArchive.Dispose(); 

希望这会有所帮助.

Hi, Is it possible to extract a file with the FileZip class even if the file already exist? atm i''m getting an error when extracting my zip file that the file does already exist.

ZipFile.ExtractToDirectory(Application.StartupPath + @"\patch001.zip", Application.StartupPath);
File.Delete(Application.StartupPath + @"\patch001.zip");

解决方案

If the library doesn''t have an ''overwrite existing'' flag, the easy thing to do, is check and delete it first.

Hi,

Try to do this:

ZipArchive zipArchive = new ZipFile.OpenRead(Application.StartupPath + @"\patch001.zip");
foreach (ZipArchiveEntry entry in zipArchive.Entries)
{
      entry.ExtractToFile(Application.StartupPath + entry.Name, true);
}
zipArchive.Dispose();

Hope this helps.
