.NET/LINK USER GUIDE Comment: Calling static generic C# method
wollmich
I've a problem to call a static generic C# method from Mathematica and
I don't find any example on the web or in your user guide.
http://www.wolfram.com/learningcenter/tutorialcollection/NETLinkUserGuide/NETLinkUserGuide.pdf
Calling a non static class (this works):
Type1 = LoadNETType["DummyLib.Class1"];
Object1 = NETNew[Type1];
Object1@Method1[];
Calling a static method in a static class (this works):
Type2 = LoadNETType["DummyLib.Class2"];
Class2`Method2[];
Calling a non static but generic class (this works):
Type3 = LoadNETType["DummyLib.Class3`1[[DummyLib.Class1]]"];
Object3 = NETNew[Type3];
Object3@Method3[];
Calling a static generic method in a static class (THIS DOESN'T
WORK!!!!) I've no idea how to call it???
The method could look like that in C#:
C#-Code:
namespace DummyLib
{
public static class Class4
{
public static T Method4<T>()
where T : new()
{
return new T();
}
}
}
With NETTypeInfo the method is listet, but I don't no idea how to pass
the type parameter?
Type4 = LoadNETType["DummyLib.Class4"];
NETTypeInfo[Type4];
Can somebody please help me. Thanks.

I've a solution which works:
NETCallGenericStaticMethod[classtype_ method_, type_, arguments___] :=
Module[{m1, m2, t1, t2},
t1 = GetTypeObject[classtype];
m1 = t1@GetMethod[method];
t2 = GetTypeObject[type];
m2 = m1@MakeGenericMethod[{t2}];
Return[m2@Invoke[Null, arguments]]];
Any other idea?

Your solution is exactly correct, and you can give yourself some
well-deserved congratulations for figuring it out. You can do
arbitrarily complicated machinations with generics in .NET/Link
already, but .NET/Link really needs some added syntax for making
generics easier to use, as well as more documentation.
One complication for your NETCallGenericStaticMethod function is that
the GetMethod call fails if the static method has overloads. You can
work around this by calling GetMethods[] and then iterating through
the list to find the one you want. I give an example of this, as well
as some more generics-related techniques, in a notebook I wrote a
little while ago called "Using LINQ from Mathematica." It is of
interest to anyone working with generics in .NET/Link, not
necessarily using LINQ. I have sent this to you separately, and I'd
be happy to send it to anyone else who is interested. Its content is
being incorporated into the .NET/Link documentation for future
versions of Mathematica.

First, Congrats to wollmich, I tried to tackle this problem but I gave
up, well done!!
I use NET/Link quite a lot to help testing our applications and I
would be interested in obtaining the document todd has mentioned, if
possible, can I have a copy?
Best
