.NET Generics constraints

[Aquarian]

I have a question in .NET Generics regarding the constraints.

How would I prevent a value type from being used as the type parameter?

say i have a generic class Foo

class Foo<T> {

}

I want to prevent T from being a value type say only structs. Integral value types are ok. (int,float,doub le). what i want is the effect something like

class Foo<T> where T not struct //instead of the T : struct
{
T()
{
//if type of T is a struct type throw exception.
}
}
I know there isnt a direct way, but i am looking at something like a check at ctor and throw an exception if the type is determined to be a struct type.

Try something like this to check if "T" is a struct
[code=vbnet]
Try
If T Is GetType(StructF ormat) Then

End If ' placed at the beginning of your class

catch ex as Exception ' placed at the end of your class
End Try

[/code]
I believe it may do what you want.
it should check as it goes along and if T becomes a struct at any time the exception should be thrown.
but I am no expert.
Hope it works or gives you an idea.
Good luck
