Solving Memory Leaks

[Ciralia]

I have a program that runs C++ for its behind-the-scenes functional operations and runs C# for its GUI portion, however, the C# GUI executable has a memory leak issue and I'm trying to track it down. The memory of the program gradually increases over time, eventually handicapping the PC. I ran .NET Memory Profiler and the items that used the most memory were:

System.WeakReference
System.Hastable.bucket[]
System.Windows.Forms
GCHandle

Since these are system items, this leads me to believe that I'm using them incorrectly in my code. That being said, here are some samples of code which I believe to be suspect for memory leaks, but I'm not sure if there is a way or how to fix them.

public class Gui
{
       // Variables
       private MyFormClass myFormVariable = null;
       private System.Collections.ArrayList myArrayList = new System.Collections.ArrayList();

       // Constructor
       public Gui()
       {
              System.Collections.ArrayList localArrayList = new System.Collections.ArrayList(myArrayList);

              object myObject = new object();
             
              myArrayList.Add(object);

              myFormVariable = new MyFormClass();

              MyMethod();
              
       }

        private void MyMethod()
        {
               System.Drawing.Point myPoint = new System.Drawing.Point (34, 3);
               
               char[] c = new char[2];
               c[0] = 'c';

               if (myFormVariable != null)
               {
                       myFormVariable.Location = myPoint;
                       myFormVariable.Name = new string (c);
               }
        }
}

Will any of these variable initializations/usages cause memory leaks? If so, how do I fix it? Of course I just gave a sample code snippet...these types of initializations are all over the code I'm working with.
