使用其原始权限复制文件

Question

使用File.Copy()方法时,文件将复制到其新目录,但会丢失其原始权限.

有没有办法复制文件,以便它不会丢失权限？

Answer 1

我相信你可以这样做:

const string sourcePath = @"c:\test.txt";
const string destinationPath = @"c:\test2.txt"

File.Copy(sourcePath, destinationPath);

FileInfo sourceFileInfo = new FileInfo(sourcePath);
FileInfo destinationFileInfo = new FileInfo(destinationPath);

FileSecurity sourceFileSecurity = sourceFileInfo.GetAccessControl();
sourceFileSecurity.SetAccessRuleProtection(true, true);
destinationFileInfo.SetAccessControl(sourceFileSecurity);
