    Unloading a dll

    How do I unload a dll using c#. Basically what I want to is test if a certain dll has been loaded if it has then I want to remove it from memory. The reason is that I want to overwrite the dll file but I can't overwrite it since the dll is being used. The dll that I am trying to unload is written in probably c or c++ so it is unmanaged code.

    Question unloading a dll

    OK I found how to get the process and the modules that are attached to those modules... now how do I remove these modules from memory... any help will be greatly appreciated...


    Code:
    private void Form1_Load(object sender, System.EventArgs e)
    {
          try
          {
               System.Diagnostics.Process[] ps = Process.GetProcesses();
               string s = "";
               for(int i = 0; i < ps.Length; i++)
               {
    	s += "\r\n" + ps[i].ProcessName;
     	try
    	{
                           foreach(ProcessModule childModule in ps[i].Modules)
    	        {
    		s += "\r\n    " + childModule.ModuleName;
    		if(childModule.ModuleName.ToUpper() == "MYDLL.DLL")
    		{
    		      //OK so I found my module now 
    		      //How do I unload this module from memory
    		}
                            }
                     }
    	 catch
    	{
    	
                    }
               }				
    
                MessageBox.Show(s);				
          }
          catch(Exception exc)
          {
                  MessageBox.Show(exc.Message);
          }
    }
