Use System.Diagnostics.Process in C#

1. The Process class in  the System.Diagnostics name space
2. // Static Start with no reference to Process Object
               Process.Start( "Notepad");
3. 
   
   //  Search for the Notepad process just created
               Process[] processArray =  Process.GetProcessesByName("notepad");

                   Console.WriteLine("Notepad started ");
               else
                   Console.WriteLine( "Notepad either reused or not started");
   
   
4. 
   
   //  Static Start with reference to Process Object 
               Process calcApp;
               calcApp  = Process.Start("Calc" );
               if (calcApp !=  null) 
                   Console.WriteLine("Calc started ");
               else
                   Console.WriteLine( "Calc either reused or not started");
5. 
   
        // Static Start with reference to Process Object
               Process IEApp  = Process.Start("iexplore" );
               if (IEApp !=  null) 
                   Console.WriteLine("IE started ");
               else
                   Console.WriteLine( "IE either reused or not started");
6. 
   
   //  Instance Start with StartInfo
               Process wordApp =  new Process();
               wordApp.StartInfo.FileName =  "winword";
                bool wordStarted = wordApp.Start();
                if (wordStarted) 
                   Console.WriteLine("Word started ");
               else
                   Console.WriteLine( "Word either reused or not started");
7. 
   
   //  Static Start with Document
               Process IEApp2 =  Process.Start("http://www.google.com" );
               if (IEApp2 ==  null)
                   Console.WriteLine("Second instance of IE started ");
               else
                   Console.WriteLine( "IE instance reused or not started");
8. 
   
   //  Instance Start with Document as StartInfo
               Process IEApp3 =  new Process();
               IEApp3.StartInfo.FileName =  "http://www.microsoft.com" ;
               bool IEstarted = IEApp3.Start();
               if (IEstarted)
                   Console.WriteLine(" IE instance started");
               else
                   Console.WriteLine("IE instance either reused or not started" );
