[c#] Running EXE with parameters

I need help in trying to execute an executable from my C# application.
Suppose the path is cPath, the EXE is HHTCtrlp.exe and the parameter that has to be passed is cParams.

How would I go about this?

The reason why the path is a variable is that there are 3 different EXE files to run and the path will change depending on which one will run, same with the parameter string.

Any help would be greatly appreciated.

ProcessStartInfo startInfo = new ProcessStartInfo(string.Concat(cPath, "\\", "HHTCtrlp.exe"));
startInfo.Arguments =cParams;
startInfo.UseShellExecute = false; 
System.Diagnostics.Process.Start(startInfo);

System.Diagnostics.Process.Start("PATH to exe", "Command Line Arguments");
