How to operate two command in c#?

Question

class testapplication
{
    static void ProcessString(string s)
    {

        {
        Directory.Move("@C:/Users/Public/TestFolder", "@C:/Users/Public/TestFolder1");<1
        Directory.Move("@C:/Users/Public/TestCase", "@C:/Users/Public/TestCase1");<2
        }
    }
}

For a example like this case, it can only run 1 and 2 cannot active.

Add it in try catch block and check if it throwing any exception on first call. — Vijay Kumbhoje, Dec 15 '15 at 02:58
You're moving two same directories, of course it won't work once you move the first directory, the directory is gone — User2012384, Dec 15 '15 at 03:00
I am sorry! the question should be wrong and now is updated! — Fabre, Dec 15 '15 at 03:04
First you should give a valid path: `"@C:/Users/Public/TestFolder"` should be `@"C:/Users/Public/TestFolder"`; Place `@` outside the `"` — sujith karivelil, Dec 15 '15 at 03:12

[Directory.Move Method (String, String)][1] Moves a file or a directory and its contents to a new location.

So at the time of execution of the second command the source becomes empty. if you need to take a copy of testFolder, as testfolder1 and testFolder2 and remove the testfolder, i prefer you to do a copy first and then perform move

try
 { 
  Directory.Copy(@"c:/Users/Public/TestFolder", @"c:/Users/Public/TestFolder1",true);// will take a copy of the directory TestFolder1
  Directory.Move(@"c:/Users/Public/TestCase", @"c:/Users/Public/TestCase1");//will move TestFolder to TestFolder2
 }
catch{//handle exception here}

Find out a new problem and with picture! Can you tell me what wrong in this case? :( — Fabre, Dec 15 '15 at 04:12

Your code depicts a move operation which will cause an error in the second line.. a copy operation will be successful :)

I think that should check accessible for source folder before move it.

See check Check if directory is accessible

I just test on my computer. It works fine with following code

if(CanRead(@"C:/Users/hai2/Desktop"))  
   Directory.Move(@"C:/Users/hai2/Desktop", @"C:/Users/hai2/Desktop1");// command 1
if(CanRead(@"C:/Users/hai2/Links"))  
   Directory.Move(@"C:/Users/hai2/Links", @"C:/Users/hai2/Links1");//command 2

Hope it helps

you should "Check if directory is accessible" before you move it – Lewis Hai Dec 15 '15 at 04:31

If you want to execute two operations at the same time, then you can start them in two separate threads. The best way to do this is to use Task functionality.

var move1 = Task.Factory.StartNew(() => Directory.Move("@C:/Users/Public/TestFolder", "@C:/Users/Public/TestFolder1"));
var move2 = Task.Factory.StartNew(() => Directory.Move("@C:/Users/Public/TestCase", "@C:/Users/Public/TestCase1"));

Task.WaitAll(move1, move2); // will wait until work is done

It will make start two asynchronous Directory.Move operations, and will continue only when both of them will be finished.

@Fabre Make sure that this directory has no files, which are now open in other applications or busy. You cannot move such directories. – Yeldar Kurmangaliyev Dec 15 '15 at 04:18
