Color EqualityIs there a way to check whether two Colors are equal? If the Colors have
different Name properties, the = operator will return false even if the A,R,G, and B properties are equal. I would like to be able to check whether two colors are equal based only on the properties that determine what color will be displayed. Is there a way to do this without writing my own method? Thanks. Both the Equals method and the = operator check for known colours. The only
way to check colour equality in a numerical manner is to compare the RGB value. Probably the easiest way is to convert to integer and compare those. -- Show quoteHide quote-- Bob Powell [MVP] Visual C#, System.Drawing Ramuseco Limited .NET consulting http://www.ramuseco.com Find great Windows Forms articles in Windows Forms Tips and Tricks http://www.bobpowell.net/tipstricks.htm Answer those GDI+ questions with the GDI+ FAQ http://www.bobpowell.net/faqmain.htm All new articles provide code in C# and VB.NET.
