Do I need to worry about Process in foreach loop

Question

Here is the piece of code, which run through all the process and when It finds the right process, code sends the message. My question is what happened to the 'proc', how to dispose that process.

//get all other (possible) running instances
        Process[] processes = Process.GetProcesses();            
        foreach (Process proc in processes)
        {
            if (proc.ProcessName.ToLower() == ProcessName.ToLower())
            {
                SendMessage(proc.MainWindowHandle, (uint)Message, IntPtr.Zero, IntPtr.Zero);
            }               
        }

Thanks in advance, Harsha

To make sure all resoucers are freed as early as possible, call Dispose on the process, when you no longer need it.

//get all other (possible) running instances
Process[] processes = Process.GetProcesses();
try
{
    foreach (Process proc in processes)
    {
    // use proc
    }
}
finally
{
    foreach (Process proc in processes)
        proc.Dispose();
    processes = null;
}

In general terms you don't need to worry about disposing or deallocating objects, unless the object implements the IDisposable interface. If it does you should either call the Dispose() method on it manually when you're finished, or wrap with a using statement to have it called automatically:

using (var disposableObject = new DisposableType())
{
    // do work with disposableObject
}
