我调用了Kernel32的复制文件方法:

[DllImport("kernel32.dll",
           CharSet = CharSet.Unicode,
           CallingConvention = CallingConvention.StdCall,
           SetLastError = true)]
        [return: MarshalAs(UnmanagedType.Bool)]
        static extern bool CopyFile(
                           [MarshalAs(UnmanagedType.LPStr)] string lpExistingFileName,
                           [MarshalAs(UnmanagedType.LPStr)] string lpNewFileName,
                           [MarshalAs(UnmanagedType.Bool)] bool bFailIfExists);
[DllImport("kernel32.dll")]
    public static extern uint GetLastError();

但是,当我调用它时,它从GetLastError()返回2,这意味着找不到文件.路径肯定存在.

string newfile = Environment.CurrentDirectory + "\\temp" + Path.GetExtension(file);
uint i;
if (!CopyFile(file, newfile, true)) i = GetLastError();

我试图通过这个解决方案绕过LongPath异常.但即使使用普通文件,它似乎也不起作用.任何帮助,将不胜感激.
