PropertyInfo.GetGetMethod 方法

定义

命名空间:

System.Reflection

程序集:

System.Runtime.dll

返回表示此属性的 MethodInfo 访问器的 get。

重载

GetGetMethod(Boolean)	当在派生类中重写时，返回此属性的公共或非公共 get 访问器。
GetGetMethod()	返回此属性的公共 get 访问器。

GetGetMethod(Boolean)

Source:

PropertyInfo.cs

当在派生类中重写时，返回此属性的公共或非公共 get 访问器。

public:
 abstract System::Reflection::MethodInfo ^ GetGetMethod(bool nonPublic);

public abstract System.Reflection.MethodInfo? GetGetMethod (bool nonPublic);

abstract member GetGetMethod : bool -> System.Reflection.MethodInfo

Public MustOverride Function GetGetMethod (nonPublic As Boolean) As MethodInfo

参数

nonPublic

Boolean

指示是否应返回非公共 get 取值函数。 如果要返回非公共取值函数，则为 true；否则为 false。

返回

MethodInfo

如果 MethodInfo 为 get，则返回表示该属性的 nonPublic 访问器的 true 对象。 如果 null 为 nonPublic 且 false 访问器是非公共的，或如果 get 为 nonPublic 但不存在 true 访问器，则返回 get。

例外

SecurityException

所请求的方法为非公共且调用方没有 ReflectionPermission 来反射此非公共方法。

示例

以下示例显示指定属性的公共或非公共 get 访问器。

using namespace System;
using namespace System::Reflection;

注解

此属性是 MethodInfo 表示 get 访问器的 。

若要使用 GetGetMethod 方法，请首先获取 类 Type。 从 中 Type获取 PropertyInfo。 在 中 PropertyInfo，使用 GetGetMethod 方法。

GetGetMethod()

Source:

PropertyInfo.cs

返回此属性的公共 get 访问器。

public:
 System::Reflection::MethodInfo ^ GetGetMethod();

public System.Reflection.MethodInfo? GetGetMethod ();

member this.GetGetMethod : unit -> System.Reflection.MethodInfo

Public Function GetGetMethod () As MethodInfo

返回

MethodInfo

MethodInfo 对象，表示此属性的公共 get 访问器；如果 null 访问器是非公共的或不存在，则为 get。

注解

这是一种方便的方法，它为参数设置为 false的nonPublic抽象GetGetMethod方法提供实现。

若要使用 GetGetMethod 方法，请首先获取 类 Type。 从 中 Type获取 PropertyInfo。 在 中 PropertyInfo，使用 GetGetMethod 方法。
