Add a reference to "System.Management" assembly

using System.Management;
...

static void FindAllProcessNameWithCommandLine()
{
    string wmiQuery = "Select * from Win32_Process";
    ManagementObjectSearcher searcher = new ManagementObjectSearcher(wmiQuery);
    ManagementObjectCollection retObjectCollection = searcher.Get();
    foreach (ManagementObject retObject in retObjectCollection)
    {
        string exename = retObject["Name"] as string;
        string commandline = retObject["CommandLine"] as string;
        Debug.WriteLine(exename + ": \'" + commandline + "\'");
    }
}
