プロパティ値

String

エラー メッセージ文字列です。The error message string.

Messageプロパティの例を次に示します。The following example demonstrates the Message property. このコード例は、MissingMemberException クラスのために提供されている大規模な例の一部です。This code example is part of a larger example provided for the MissingMemberException class.

try
{
    // Attempt to access a static AnotherField field defined in the App class.
    // However, because the App class does not define this field,
    // a MissingFieldException is thrown.
    App::typeid->InvokeMember("AnotherField", BindingFlags::Static |
        BindingFlags::GetField, nullptr, nullptr, nullptr);
}
catch (MissingMemberException^ ex)
{
    // Notice that this code is catching MissingMemberException which is the
    // base class of MissingMethodException and MissingFieldException.
    // Show the user that the AnotherField field cannot be accessed.
    Console::WriteLine("Unable to access the AnotherField field: {0}",
        ex->Message);
}
try
{
    // Attempt to access a static AnotherField field defined in the App class.
    // However, because the App class does not define this field,
    // a MissingFieldException is thrown.
    typeof(App).InvokeMember("AnotherField", BindingFlags.Static |
        BindingFlags.GetField, null, null, null);
}
catch (MissingMemberException e)
{
 // Notice that this code is catching MissingMemberException which is the
 // base class of MissingMethodException and MissingFieldException.
 // Show the user that the AnotherField field cannot be accessed.
 Console.WriteLine("Unable to access the AnotherField field: {0}", e.Message);
}
    Try
        ' Attempt to access a static AnotherField field defined in the App class.
        ' However, because the App class does not define this field, 
        ' a MissingFieldException is thrown.
        GetType(App).InvokeMember("AnotherField", BindingFlags.Static Or BindingFlags.GetField, _
                                   Nothing, Nothing, Nothing)
    Catch e As MissingMemberException
        ' Notice that this code is catching MissingMemberException which is the  
        ' base class of MissingMethodException and MissingFieldException.
        ' Show the user that the AnotherField field cannot be accessed.
        Console.WriteLine("Unable to access the AnotherField field: {0}", e.Message)
    End Try
End Sub 

注釈

オブジェクトの構築時にクラス名が指定されていない場合は、基本クラスから継承された既定のテキスト文字列が返されます。If the class name is not specified when the object is constructed, the default text string inherited from the base class is returned.

このプロパティは Message 、をオーバーライドします。This property overrides Message. エラーメッセージはローカライズされている必要があります。The error message should be localized.

このプロパティは読み取り専用です。This property is read-only.
