注解

MethodInfo类表示类型的方法。The MethodInfo class represents a method of a type. 您可以使用MethodInfo对象获取有关对象所表示的方法的信息,以及调用方法。You can use a MethodInfo object to obtain information about the method that the object represents and to invoke the method. 例如:For example:

MethodInfo可以通过MethodInfo MethodInfo.MakeGenericMethod调用或方法Type.GetMethod来实例化实例,也可以通过调用表示泛型方法定义的对象的方法来实例化实例。 Type.GetMethodsYou can instantiate a MethodInfo instances by calling the Type.GetMethods or Type.GetMethod method, or by calling the MethodInfo.MakeGenericMethod method of a MethodInfo object that represents a generic method definition.

有关特定于泛型方法的术语的固定条件列表,请参见IsGenericMethod属性。For a list of the invariant conditions for terms specific to generic methods, see the IsGenericMethod property. 有关泛型反射中使用的其他术语的固定条件列表,请参见IsGenericType属性。For a list of the invariant conditions for other terms used in generic reflection, see the IsGenericType property.
