C＃ - 重命名目录的方法 [英] C# - Ways to rename a directory

问题描述

我正在使用 Directory.Move（oldDir，newDir）重命名目录。现在，我得到一个 IOException ，说访问路径oldDir被拒绝。但是，如果我右键单击资源管理器中的目录，我可以重命名它，没有任何问题。

所以我的问题是：是否有其他方法要重命名目录而不使用 Directory.Move ？

我以为使用命令shell（ Process.Start（）），但这应该是我最后一次这样做。

<更多细节

程序仍在运行，我得到异常，可以在Windows资源管理器中手动重命名（右键单击 - >重命名），而我的光标在catch块的断点上暂停。我还尝试在 Directory.Move 中设置断点，成功地将资源管理器中的目录重命名（再次返回），逐步执行 Directory.Move 并且最后在$ code> catch（IOException）再次。

这是我的代码

  public bool Copy（）
 {
 string destPathRelease = ThisUser.DestPath +\\Release; 
 
 if（Directory.Exists（destPathRelease））
 {
 try 
 {
 string newPath = ThisUser.DestPath +'\\'+ （string.IsNullOrEmpty（currBuildLabel）？（Release+'_'+ DateTime.Now.ToString（yyyyMMdd_HHmmss））：currBranchName）+'。'+ currBuildLabel; 
 Directory.Move（destPathRelease，newPath）; 
} 
 catch（IOException）
 {
 //断点
} 
} 
} 
  

正如您所看到的，我刚刚输入了该方法。

由于这种方式对我来说无法工作，我需要找到另一种方法。

解决方案

  public bool Copy（）
 {
 string destPathRelease = ThisUser.DestPath +\\Release; 
 
 SHFILEOPSTRUCT struc = new SHFILEOPSTRUCT（）; 
 
 struc.hNameMappings = IntPtr.Zero; 
 struc.hwnd = IntPtr.Zero; 
 struc.lpszProgressTitle =重命名发行目录; 
 struc.pFrom = destPathRelease +'\0'; 
 struc.pTo = ThisUser.DestPath +'\\'+（string.IsNullOrEmpty（this.currBuildLabel）？（Release+'_'+ DateTime.Now.ToString（yyyyMMdd_HHmmss））： this.currBranchName）+'。'+ this.currBuildLabel +'\0'; 
 struc.wFunc = FileFuncFlags.FO_RENAME; 
 
 int ret = SHFileOperation（ref struc）; 
} 
  

请注意使用 pTo 和 pFrom 作为零分隔的双零终止字符串。

解决方案

p>您可以尝试使用P / Invoke调用 SHFileOperation API（或 IFileOperation 界面）。这是Explorer在理论上使用的，所以它应该更直接地复制功能。

I'm using Directory.Move(oldDir, newDir) to rename a directory. Every now and then I get an IOException saying "Access to the path 'oldDir' is denied". However if I right click the directory in the explorer I can rename it without any issues.

So my question is: Are there any other ways to rename a directory without using Directory.Move?

I thought of using the command shell (Process.Start()) but this should be my last way of doing it.

Further details

The program is still running, I get the exception and can rename it manually in windows explorer (right click -> rename) while my cursor is paused on the breakpoint in the catch block. I also tried setting a breakpoint at Directory.Move, successfully renamed the directory in explorer (and back again), stepped over Directory.Move and ended up in the catch (IOException) again.

Here is my code

public bool Copy()
{
    string destPathRelease = ThisUser.DestPath + "\\Release";

    if (Directory.Exists(destPathRelease))
    {
        try
        {
            string newPath = ThisUser.DestPath + '\\' + (string.IsNullOrEmpty(currBuildLabel) ? ("Release" + '_' + DateTime.Now.ToString("yyyyMMdd_HHmmss")) : currBranchName) + '.' + currBuildLabel;
            Directory.Move(destPathRelease, newPath);
        }   
        catch (IOException)
        {
           // Breakpoint
        }
    }
}

As you can see I just entered the method. I never touched the directory in my program before.

Since this way is not working for me I need to find another way to do so.

Solution

public bool Copy()
{
    string destPathRelease = ThisUser.DestPath + "\\Release";

    SHFILEOPSTRUCT struc = new SHFILEOPSTRUCT();

    struc.hNameMappings = IntPtr.Zero;
    struc.hwnd = IntPtr.Zero;
    struc.lpszProgressTitle = "Rename Release directory";
    struc.pFrom = destPathRelease + '\0';
    struc.pTo = ThisUser.DestPath + '\\' + (string.IsNullOrEmpty(this.currBuildLabel) ? ("Release" + '_' + DateTime.Now.ToString("yyyyMMdd_HHmmss")) : this.currBranchName) + '.' + this.currBuildLabel + '\0';
    struc.wFunc = FileFuncFlags.FO_RENAME;

    int ret = SHFileOperation(ref struc);
}

Please note it's important to use pTo and pFrom as zero delimited double zero terminated strings.

解决方案

You could try using P/Invoke to call the SHFileOperation API (or the IFileOperation interface). This is what Explorer uses in theory, so it should replicate the functionality more directly.
