如何在Visual Studio 2008调试器中查看GUID的值？

Question

When you look at a GUID values item in the watch window you do not see the value of the item, when you expand the item you just see “ Empty ” this is very misleading!

You have to add “ToString()” to the value to see something useful.

So how do I get Visual Studio to add the “ToString()” it's self?

I am using VB.NET if it make a difference.

Take a look here: Visualizing GUIDs in the Visual Studio 2008 debugger

Thanks that worked well, however I had to change

<Assembly: DebuggerDisplay("{ToString}", Target:=GetType(Guid))> 

to

<Assembly: DebuggerDisplay("{ToString()}", Target:=GetType(Guid))>

so it also worked from C#

When i add a guid to the watch window, it shows its value without having to expand it (the ToString() is automatically used).

How are you creating your guid? If you are using

Guid x = new Guid();

then yes, it will be an "empty" guid. If you use

Guid x = Guid.NewGuid();

then you will see that it has a value.
