What ever happened to less is more? Come on admit it, you are just jealous that you can't do this. :) Now the C# developers decide to take the high road about not using mutable objects?

That would be called like

MyEnum enum1;

enum1 = enum1.FromString(thestring);

IMO that’s not natural at all.

Here's your solution: public static Enum FromString(this Enum theEnum, string fromString) { return (Enum)Enum.Parse(theEnum.GetType(), fromString); } Seriously, I saw this post and I cannot believe it was never resolved.

Here’s your solution:

public static Enum FromString(this Enum theEnum, string fromString)
{
return (Enum)Enum.Parse(theEnum.GetType(), fromString);
}

I completely understand what he is trying to do. If you had ownership of the code for System.String, you wouldn't build a method on that class to convert it to some random enum. That has nothing to do with the natural behaviour that should be encapsulated within that class. It's not the responsibility of String to know about all the enums out there. But adding an extension to the enum itself is like encapsulating that behaviour within the type (in this case an enum) itself. It's very natural. But making a string covert itself to an enum is wicked evil. I defense of the OP. I completely understand what he is trying to do.

I am using a Matrix struct that is a part of the XNA framework in c#. I was porting over some C++ code that was using nested arrays to describe a matrix such as: a[0][0] = Matrix.m11 Now, the Matrix struct is awesome and used in alot of places but the one thing that I can't do with it is access the rows and columns by indexer like myMatrix[0][0]. I figured I could just make an extender like Matrix.SetValueByRowAndColumn(this Matrix m, int rowindex, int colindex, float value) or something but seeing that Matrix m is passed over byVal and not byRef, you can't change any of the values! And I NEED to write it this way, I have nested loops that run through the rows and columns of my matrix (from the ported code) that would be very sloppy if I broke them out. So what was my simple solution? I just changed the "this" into a "ref" and now instead of an extender, I've got a static method that looks like: MyNamespace.MyClass.SetValueByRowAndColumn(ref myMatrix, (int)row, (int)col, (float)val); It's not as pretty and completely defeats the purpose, but after reading through this page and all of the comments I was ready to shove my head in the oven. Figuring out that there was a simple fix made me ecstatic! Well I found this site after running into the same problem. I am using a Matrix struct that is a part of the XNA framework in c#.

I always liked Maths better than literature in High School, so I guess that's why I like C# better :) Thanks for all your comments. I am glad that you see it the same way Rick (the first part).
