本C＃，Visual Studio 2010和.NET 4.0。我想比较两个的System.Drawing.Color 的对象。

This C#, VS2010 and .NET 4.0. I'm trying to compare two System.Drawing.Color objects.

的值 mStartColor.ToArgb（）是 16777215 。

的值 Col​​or.Transparent.ToArgb（）是 16777215 。

mStartColor 1所述的价值;＆GT; Color.Transparent 是真。

如何平等实施了颜色对象？

谢谢大家。我有我的答案，但它并没有多大意义，我（见我的意见蒂姆和戴夫的回答如下）。我会纪念Tim的岗位作为答案，他是第一个回复，但戴夫的回答也同样丰富。

This is because the Equals and Equality members determine equivalency using more than just the ARGB value of the colors. For example, Black and FromArgb(0,0,0) are not considered equal, since Black is a named color and FromArgb(0,0,0) is not"
