Returns an array of Type objects that represent the type arguments of a generic method or the type parameters of a generic method definition.

Public Overridable Function GetGenericArguments () As Type()

Returns

Type[]

An array of Type objects that represent the type arguments of a generic method or the type parameters of a generic method definition. Returns an empty array if the current method is not a generic method.

Attributes
ComVisibleAttribute

Exceptions

NotSupportedException

This method is not overridden in a derived class.

Remarks

The elements of the returned array are in the order in which they appear in the list of type parameters for the generic method.

  • If the current method is a closed constructed method (that is, the ContainsGenericParameters property returns false), the array returned by the GetGenericArguments method contains the types that have been assigned to the generic type parameters of the generic method definition.

  • If the current method is a generic method definition, the array contains the type parameters.

  • If the current method is an open constructed method (that is, the ContainsGenericParameters property returns true) in which specific types have been assigned to some type parameters and type parameters of enclosing generic types have been assigned to other type parameters, the array contains both types and type parameters. Use the IsGenericParameter property to tell them apart. For a demonstration of this scenario, see the code example provided for the ContainsGenericParameters property.

  • If the current method is a constructor, the returned array is an empty array in .NET 11 and later. In .NET 10 and earlier versions, the GetGenericArguments method throws NotSupportedException.

For a list of the invariant conditions for terms specific to generic methods, see the IsGenericMethod property. For a list of the invariant conditions for other terms used in generic reflection, see the Type.IsGenericType property.
