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 IsGenericType property.

Notes to Inheritors

When you inherit from MethodInfo, you must override MethodInfo.GetBaseDefinition, MethodInfo.ReturnType, MethodInfo.ReturnTypeCustomAttributes, MethodBase.GetParameters, MethodBase.GetMethodImplementationFlags, MethodBase.MethodHandle, MethodBase.Attributes, MethodBase.Invoke, MemberInfo.Name, MemberInfo.MemberType, MemberInfo.DeclaringType, MemberInfo.ReflectedType, MemberInfo.GetCustomAttributes, MemberInfo.GetCustomAttributes, and MemberInfo.IsDefined.
