返回表示此属性的 MethodInfo 访问器的 set。

重载

GetSetMethod(Boolean)	当在派生类中重写时，返回此属性的 `set` 访问器。
GetSetMethod()	返回此属性的公共 `set` 访问器。

GetSetMethod(Boolean)

当在派生类中重写时，返回此属性的 set 访问器。

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

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

public abstract System.Reflection.MethodInfo GetSetMethod (bool nonPublic);

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

Public MustOverride Function GetSetMethod (nonPublic As Boolean) As MethodInfo

参数

nonPublic: Boolean

指示如果取值函数为非公共，是否应将其返回。如果要返回非公共取值函数，则为 true；否则为 false。

MethodInfo

此属性的 Set 方法或 null，如下表所示。

“值”	条件
此属性的 `Set` 方法。	`set` 访问器是公共的。或者，`nonPublic` 为 `true` 且 `set` 访问器是非公共的。
`null`	`nonPublic` 为 `true`，但属性为只读。或者，`nonPublic` 为 `false` 且 `set` 访问器是非公共的。或者，没有 `set` 访问器。

实现

GetSetMethod(Boolean)

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 set 属性的访问器。

using namespace System;
using namespace System::Reflection;

// Define a property.

         {
            caption = value;
         }
      }

   }

注解

若要使用 GetSetMethod 方法，请首先获取类 Type 。从 Type 获取 PropertyInfo 。在 PropertyInfo 中，使用 GetSetMethod 方法。

适用于

GetSetMethod()

返回此属性的公共 set 访问器。

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

public:
 virtual System::Reflection::MethodInfo ^ GetSetMethod();

public System.Reflection.MethodInfo? GetSetMethod ();

public System.Reflection.MethodInfo GetSetMethod ();

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

abstract member GetSetMethod : unit -> System.Reflection.MethodInfo
override this.GetSetMethod : unit -> System.Reflection.MethodInfo

Public Function GetSetMethod () As MethodInfo

MethodInfo

如果 MethodInfo 访问器是公共的，则为表示此属性的 Set 方法的 set 对象；如果 null 访问器是非公共的，则为 set。

实现

GetSetMethod()

注解

这是一种便捷方法，它为将参数设置为的抽象方法 GetSetMethod nonPublic 提供实现 false 。

若要使用 GetSetMethod 方法，请首先获取类 Type 。从 Type 获取 PropertyInfo 。在 PropertyInfo 中，使用 GetSetMethod 方法。
