Introduction

in some times devolpers need to run multiline commands twards the windwos cmd to do Some work they need,this approach might be used in a wide area of applications , now as my effort in search i didn't see  such this approach so if there is some approach more reliable and easier than this so you can use it .

So this is the sample output for our application : 

Background

Some time before , i searched about a solutions to do this task but what i found wasn't suitable  so i search and search , Accidentally i see some files that it's extention called "cmd" i think in some simple ways to do it by creating a file with "cmd" extention and run it ASync with your app , you would do this through your code  .

in the next section i will explain this simple way with example  .

Using the code

First thing you should think about it is to creating the file if not exist , if file exist and your Command parameter changed , you would reset the content of the file .

The best way to do all this is the use of File.WriteAllText(string FileName ,string Content) ; so for Synchronization Problems before write any content to the file first we will check that there is no other (read / write ) operations runs twards the file then we will use this Methode :

IsFileLocked(FileInfo file) 

protected static bool IsFileLocked(FileInfo file)
      {
            FileStream stream = null;
            try
            {
                stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None);
            }
            catch (IOException)
            {
                return true;
            }
            finally
            {
                if (stream != null)
                    stream.Close();
            }
            return false;
       }

then now we can start writting our Content Line by Line to the file using this Code : 

WriteContentToFile(string cmdfilename , string[] lines)

 private void WriteContentToFile(string Cmdfilename , string[] lines)
        {
        retray:
            if (!IsFileLocked(new FileInfo(Cmdfilename)))
            {   
                    string content = "";
                    foreach (string str in lines)
                    {
                        content += str + "\n";
                    }
                    File.WriteAllText(Cmdfilename, content);
            }
            else
            {
                goto retray;
            }
        }

RunCMDScript(object scriptPath)

 private void RunCMDScript(object scriptPath)
        {
            System.Diagnostics.ProcessStartInfo procStartInfo = 
                                       new System.Diagnostics.ProcessStartInfo(scriptPath.ToString());
            // Now we create a process, assign its ProcessStartInfo and start it
            System.Diagnostics.Process proc = new System.Diagnostics.Process();
            proc.StartInfo = procStartInfo;
            proc.Start();
        }

cd / 
C:

dir

cd "Program Files"

dir

pause

public void RunMultiLineCommand()
        {
            char c = '"';
            string[] cmdarr = new string[] 
           { "cd /", "C:", "dir", string.Format("cd {0}Program Files{0}" ,c ) , "dir", "pause" };
            string filename= System.AppDomain.CurrentDomain.BaseDirectory + "testcmd.cmd";
            WriteContentToFile(filename,cmdarr);
            Thread objThread = new Thread(new ParameterizedThreadStart(RunCMDScript));
            objThread.IsBackground = true;
            objThread.Priority = ThreadPriority.AboveNormal;
            objThread.Start(filename);
        }

After allof this i hope that i provide thing that make your work more easier you Can dwonload the attached example fill free to ask about any thing on this mail {khairymohamed983@gmail.com}
