Type.DeclaringType Property

Gets the type that declares the current nested type or generic type parameter.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public override Type DeclaringType { get; }

Property Value

Type: System.Type
A Type object representing the enclosing type, if the current type is a nested type; or the generic type definition, if the current type is a type parameter of a generic type; or the type that declares the generic method, if the current type is a type parameter of a generic method; otherwise, null.

If the current Type object represents a type parameter of a generic type, this property returns the generic type definition.

If the current Type object represents a type parameter of a generic method, this property returns the type that contains the generic method definition. If the type is generic, the generic type definition is returned.

If the current Type represents a type parameter in the definition of a generic type or generic method, the DeclaringType and DeclaringMethod properties identify the generic type definition or generic method definition where the generic type parameter was originally defined:

  • If the DeclaringMethod property returns a MethodInfo, that MethodInfo represents a generic method definition, and the current Type object represents a type parameter of that generic method definition.

  • If the DeclaringMethod property returns null, then the DeclaringType property always returns a Type object representing a generic type definition, and the current Type object represents a type parameter of that generic type definition.

  • Getting the DeclaringType property on a type whose IsGenericParameter property is false throws an InvalidOperationException.

This example displays the declaring type of a method in a derived class.


using System;
using System.Reflection;

public abstract class Example
{

   public abstract class MyClassA
   {
      public abstract int m();
   }

   public abstract class MyClassB : MyClassA
   {
   }

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      outputBlock.Text += String.Format("The declaring type of m is {0}.",
          typeof(MyClassB).GetMethod("m").DeclaringType) + "\n";
   }
}
