I know <T> is instance type, but I can't to know which type is T. The following code will get a compile error ('T' is a 'type parameter' but is used like a 'variable')
Please help me!!
public class Test<T>
{
public Test(){}
public void DoSomething()
{
if (T is INullableValue)
Do Case 1
elseif (T is ISomeInterface)
Do Case 2
}
}

How to know <T> of generic type
ASP.Confused
if( typeof(T).GetInterface("System.INullableValue") != null)
; // Do something
else
; // Do something
Don't be tempted (as I was, if you read this before I corrected it) to replace this with "if typeof(T) is INullableValue", it won't work since then you would be checking if the class Type implements INullableValue (which it doesn't).

What you want in your function:
public void DoSomething(T MyVariable)
{
if (MyVariable is INullableValue)
; // Do something
else
; // Do something else.
}
