错误重命名目录时拒绝访问路径 [英] Error Access to the path is denied when Rename a Directory

问题描述

我想重命名一个文件夹，其中新名称在文本框中输入

 txtFilenFolderName 

  protected   void  btnUpdate_Click（ object  sender，EventArgs e）
 {
  string  [] values = EditValue; 
 
  string  oldpath = values [ 0 ];  //   =D：\\C＃Projects \\website \\Lecturer \\giangvien \\新文件夹 
 
  string  oldName = values [ 2 ] ;  //   =新文件夹 
 
  string  newName = txtFilenFolderName.Text;  //   =新文件夹1  
  string  newPath =  string  .Empty; 
 
 
  if （oldName！= newName）
 {
 newPath = oldpath.Replace（oldName，新名字）; 
 Directory.Move（oldpath，newPath）; 
} 
  else  
 lblmessage2.Text =  新名称不得与旧名称; 
} 
} 

尝试调试：

 oldpath =   D：\\C＃Projects \\\ \\website \\Lecturer \\giangvien\\New folder 
 oldName = 新文件夹
 newName = 新 Folder1 
 newpath =   D： \\\\＃Projects \\website \\Lecturer \\giangvien \\New folder1 

一切似乎都是正确的，但是当我点击按钮编辑--->重命名--->更新--->发生错误：

拒绝访问路径D：\\C＃Projects \\website \\Lecturer \\giangvien \\New folder

解决方案

你要么没有权限重命名文件夹，要么就是文件该文件夹中的某个位置或其子文件夹保持打开状态。如果文件夹中有文件打开，则无法重命名文件夹路径的任何部分。

您的目录移动方法调用应位于try catch块内

 尝试 
 {
 Directory.Move（oldpath，newPath）; 
} 
  catch （UnauthorizedAccessException ex）
 {
  //  用户无权将目录从源位置移动到目标位置。 
} 
 carch（例外e）
 {
  //  所有其他例外。 
} 

I want to rename the a folder with the new name inputed in a Textbox

txtFilenFolderName

protected void btnUpdate_Click(object sender, EventArgs e)
   {
           string[] values = EditValue;

           string oldpath = values[0];// = "D:\\C#Projects\\website\\Lecturer\\giangvien\\New folder"

           string oldName = values[2]; //= New Folder

           string newName = txtFilenFolderName.Text; //= New Folder1
           string newPath = string.Empty;


           if (oldName != newName)
           {
                   newPath = oldpath.Replace(oldName, newName);
                   Directory.Move(oldpath, newPath);
           }
           else
                lblmessage2.Text = "New name must not be the same as the old ";
       }
   }

Try to debug:

oldpath = "D:\\C#Projects\\website\\Lecturer\\giangvien\\New folder"
 oldName = New Folder
newName= New Folder1
newpath = "D:\\C#Projects\\website\\Lecturer\\giangvien\\New folder1"

Everything seems right, but I when I click on buton Edit ---> rename---> Update---> an error occur:
Access to the path is denied D:\\C#Projects\\website\\Lecturer\\giangvien\\New folder

Help!!!

解决方案

You either don't have permissions to rename the folder or there's a file somewhere in that folder or its subfolders that's being held open. You cannot rename any part of a folderpath if there is a file open in it.

Your directory move method call should be inside a try catch block

try
{
  Directory.Move(oldpath, newPath);
}
catch(UnauthorizedAccessException  ex)
{
   //User have no permission to move directory from source to destination location.
}
carch(Exception e)
{
   //all others exception.
}
