Remarks

Instances of MethodInfo are obtained by calling the GetMethods or GetMethod method of a Type object or of an object that derives from Type, or by calling the MakeGenericMethod method of a MethodInfo that represents a generic method definition.

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.

In Silverlight-based applications, you cannot derive new types from MethodInfo.
