    copied!<p>I'm having trouble with a memory leak in C#. I'm seeing the memory usage in process manager increasing 10-20mb (and more) when no new objects should be getting created.</p> <p>q1) I am under the impression that managed objects will automatically be deleted by the GC. But when I profile the memory usage using dotTrace, there seems to be +10k instances (in the show new / dead differences) of a basic object I wrote. I found the place that it would be leaking if this were c++, </p> <pre><code>public void TriggerEvent(string tEvent) { oVariable tVar = GetVar(tEvent); if (tVar != null) sVariableParser.TriggerEvent(tVar); else { tVar = new oVariable("@CXZ_TEMP_VAR", tEvent, 0, this); tVar._BlockDependancies = true; sVariableParser.TriggerEvent(tVar); } } </code></pre> <p>Where oVariable is defined as</p> <pre><code>class oVariable : IComparable </code></pre> <p>It seems that the GC is not deleting the new'd oVariables, I am wondering do I need to implement oVariable as IDisposable and make a specific system call to make sure the GC collects it? There are also a few other custom objects within oVariable, but I was under the impression that simple objects which don't use anything external (no COM objects etc) should automatically be managed, or am I mistaken and I've been created unmanaged data structures? </p> <p>q2) Even with dotTrace Memory showing a lot of new oVariables where there should be zero (maybe the GC is lazy), I still have a feeling the memory leak could be coming from the windows forms, specifically DataGridViews. I was wondering if someone could tell me if I need to do any specific memory deallocation function calls after invoking a DGV update/redraw using </p> <pre><code>tGridView.Invoke(new UpdateGridViewCallBack(RedrawGlobalsViewGridView), tGridView); </code></pre> <p>I had assumed the new'd call back would clean up after itself. </p>
