PropertyInfo.GetSetMethod 方法

定義

命名空間:

System.Reflection

組件:

System.Runtime.dll

傳回 MethodInfo，表示這個屬性的 set 存取子。

多載

GetSetMethod(Boolean)	當在衍生類別中覆寫時，傳回這個屬性的 set 存取子。
GetSetMethod()	傳回這個屬性的公用 set 存取子。

GetSetMethod(Boolean)

來源:

PropertyInfo.cs

當在衍生類別中覆寫時，傳回這個屬性的 set 存取子。

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

參數

nonPublic

Boolean

指出若為非公用存取子，是否應該傳回。 如果要傳回非公用存取子，則為 true否則為 false。

傳回

MethodInfo

這個屬性的 Set 方法或 null，如下表所示。

值	條件
這個屬性的 Set 方法。	set 存取子為公用，或 nonPublic 為 true 且 set 存取子為非公用。
null	nonPublic 為 true，但屬性為唯讀，或 nonPublic 為 false 且 set 存取子為非公用，或沒有 set 存取子。

例外狀況

SecurityException

要求的方法為非公用，而且呼叫端沒有 ReflectionPermission 可以反映這個非公用方法。

範例

下列範例會顯示 set 指定屬性的 存取子。

備註

若要使用 GetSetMethod 方法，請先取得 類別 Type。 從取得 TypePropertyInfo。 從使用 PropertyInfoGetSetMethod 方法。

GetSetMethod()

來源:

PropertyInfo.cs

傳回這個屬性的公用 set 存取子。

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

public System.Reflection.MethodInfo? GetSetMethod ();

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

Public Function GetSetMethod () As MethodInfo

傳回

MethodInfo

MethodInfo 物件，代表這個屬性的 Set 方法 (如果 set 存取子是公用的)，或 null (如果 set 存取子不是公用的)。

備註

這是一種便利的方法，可為抽象 GetSetMethod 方法提供實作， nonPublic 並將 參數設定為 false。
