Running Instance in C#

I use this snippet to detect if an instance of my application is already running.

public static Process RunningInstance()  
 {  
    Process current = Process.GetCurrentProcess();  
    Process[] processes = Process.GetProcessesByName (current.ProcessName);  
  
     //Loop through the running processes in with the same name  
     foreach (Process process in processes)  
     {  
        //Ignore the current process  
         if (process.Id != current.Id)  
        {  
            //Make sure that the process is running from the exe file.  
             if (Assembly.GetExecutingAssembly().Location.Replace("/", "\\") == current.MainModule.FileName)  
             {  
                //Return the other process instance.  
                return process;  
             }  
         }  
     }  
     //No other instance was found, return null.  
     return null;  
 }  

However, I was thinking, is there a way to parse send the arguments in the current process to the already running process. Like in an app that adds files, I would like to kill the new process but send it's arguments to the already running process.
