copied!<p>I've recently noticed some behaviour with the Visual Studio Designer (C#) that I don't understand and was wondering if someone could clarify...</p> <p>One some of my Windows Forms, the first line of the designer generated code reads;</p> <pre><code>this.components = new System.ComponentModel.Container(); </code></pre> <p>When this is the case, the dispose method, in that same designer file, the dispose method places two "Dispose" calls within the case "if" condition as follows;</p> <pre><code> protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); base.Dispose(disposing); } } </code></pre> <p>i.e. Nothing is called unless disposing is true, AND components is not null.</p> <p>On some other forms, that first line in the designer generated code is missing. In these cases the base.Dispose call is outside the "if" condition as such...</p> <pre><code> protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } </code></pre> <p>I have noticed this while tracking down a bug with a form not closing, where this.components was null, yet the base.Dispose call was inside that condition (I suspect the designer code had been tampered with but that's another story.</p> <p>What controls this behaviour?</p> <p>(Some earlier forms in the project were created in VS 2005 and we now use VS 2008 - clue?)</p>
