How to move txt file to other folder?

I try to write a console app C# to move my etxt files to another folder. The functions just copies certain .txt files from folder A to folder AA

string source = "C:\\A\\ResultClassA.txt";
File.Move(Source, "C:\\AA");

But its always giving this error message:

Access to the path is denied.

Troubleshooting tips: Make sure you have sufficient privileges to access this resource. If you are attempting to access a file, make sure it is not ReadOnly. Get general help for this exception.

Do i really need to set my folder开发者_如何学编程 A and folder B to "NOT ReadOnly" attribute before "File.move" code are execuse? and set to read only back after success moved?

Thanks. By Hero .


You need to specify the full path and make sure the path C:\AA exists

string source = "C:\\A\\ResultClassA.txt";
File.Move(Source, "C:\\AA\\ResultClassA.txt");

See here for good sample

using System;
using System.IO;
class Test 
{
    public static void Main() 
    {
        string path = @"c:\temp\MyTest.txt";
        string path2 = @"c:\temp2\MyTest.txt";
        try 
        {
            if (!File.Exists(path)) 
            {
                // This statement ensures that the file is created,
                // but the handle is not kept.
                using (FileStream fs = File.Create(path)) {}
            }

            // Ensure that the target does not exist.
            if (File.Exists(path2)) 
            File.Delete(path2);

            // Move the file.
            File.Move(path, path2);
            Console.WriteLine("{0} was moved to {1}.", path, path2);

            // See if the original exists now.
            if (File.Exists(path)) 
            {
                Console.WriteLine("The original file still exists, which is unexpected.");
            } 
            else 
            {
                Console.WriteLine("The original file no longer exists, which is expected.");
            }           

        } 
        catch (Exception e) 
        {
            Console.WriteLine("The process failed: {0}", e.ToString());
        }
    }
}


Hero, you are moving from a file name to a folder name, try to specify a file name with extension inside the C:\AA folder.

does AA exist already on C ?
