當在派生類別中覆寫時，會回傳該屬性的公用或非公有 get 存取器。

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

參數

nonPublic
Boolean

指示是否應歸還非公開 get 存取者。 true若需歸還非公開存取者;否則，。 false

傳回

MethodInfo

MethodInfo get代表此屬性的存取器物件，若nonPublic為 true。 如果null是nonPublicfalse且 存取器為非公開，則回傳 get ，或是nonPublictrue但不get存在存取器。

實作

GetGetMethod(Boolean)

例外狀況

SecurityException

所請求的方法為非公開，呼叫者無需 ReflectionPermission 反映此非公開方法。

範例

以下範例顯示該屬性的公開或非公開 get 存取器。

using System;
using System.Reflection;

// Define a property.

    }
}

        Console.WriteLine ("\nReflection.PropertyInfo");

        // Get the type and PropertyInfo for two separate properties.
        Type MyTypea = Type.GetType("Myproperty");
        PropertyInfo Mypropertyinfoa = MyTypea.GetProperty("Caption");
