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

txtFilenFolderName

C#

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:

VB

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!!!

That means the folder does not have permission to access it. Check it's properties and try to find the permissions inside it.

Post as solution. Perhaps mention the identity of the app pool needs permissions.

Not sure, but OP says it has all the permissions. See below comment.

Solution 1

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.

yes, because New Folder still has a subfolder inside. So that I cannot rename folder which has subfolder inside?????

No, I said you cannot rename a any part of a folder path that has a FILE BEING HELD OPEN.

Solution 2

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

C#

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.
}
