C# Type IsGenericTypeDefinition

Description

Type IsGenericTypeDefinition gets a value indicating whether the current Type represents a generic type definition, from which other generic types can be constructed.

Syntax

Type.IsGenericTypeDefinition has the following syntax.


public virtual bool IsGenericTypeDefinition { get; }

Example

The following example displays information about a type, including whether or not it is a generic type definition.


// w ww.  j  ava2 s  . co  m

using System;
using System.Reflection;
using System.Collections.Generic;

public class Base<T, U> { }

public class Derived<V> : Base<int, V> { }

public class Test
{
    public static void Main()
    {
        Type derivedType = typeof(Derived<>);
        DisplayGenericTypeInfo(derivedType);

        // Display its open constructed base type.
        DisplayGenericTypeInfo(derivedType.BaseType);
    }

    private static void DisplayGenericTypeInfo(Type t)
    {
        Console.WriteLine(t);

        Console.WriteLine(t.IsGenericTypeDefinition);

        Console.WriteLine(t.IsGenericType);

        Console.WriteLine(t.ContainsGenericParameters);
    }
}

The code above generates the following result.
