Examples

The following example demonstrates the Message property. This code example is part of a larger example provided for the MissingMethodException class.

try
{
    // Attempt to call a static DoSomething method defined in the App class.
    // However, because the App class does not define this method,
    // a MissingMethodException is thrown.
    App::typeid->InvokeMember("DoSomething", BindingFlags::Static |
        BindingFlags::InvokeMethod, nullptr, nullptr, nullptr);
}
catch (MissingMethodException^ ex)
{
    // Show the user that the DoSomething method cannot be called.
    Console::WriteLine("Unable to call the DoSomething method: {0}",
        ex->Message);
}

try
{
    // Attempt to call a static DoSomething method defined in the App class.
    // However, because the App class does not define this method,
    // a MissingMethodException is thrown.
    typeof(App).InvokeMember("DoSomething", BindingFlags.Static |
        BindingFlags.InvokeMethod, null, null, null);
}
catch (MissingMethodException e)
{
    // Show the user that the DoSomething method cannot be called.
    Console.WriteLine("Unable to call the DoSomething method: {0}", e.Message);
}

try
    // Attempt to call a static DoSomething method defined in the App class.
    // However, because the App class does not define this method,
    // a MissingMethodException is thrown.
    typeof<App>.InvokeMember("DoSomething", BindingFlags.Static ||| BindingFlags.InvokeMethod, null, null, null)
    |> ignore
with :? MissingMethodException as e ->
    // Show the user that the DoSomething method cannot be called.
    printfn $"Unable to call the DoSomething method: {e.Message}"

Try
    ' Attempt to call a static DoSomething method defined in the App class.
    ' However, because the App class does not define this method, 
    ' a MissingMethodException is thrown.
    GetType(App).InvokeMember("DoSomething", BindingFlags.Static Or BindingFlags.InvokeMethod, _
                               Nothing, Nothing, Nothing)
Catch e As MissingMethodException
    ' Show the user that the DoSomething method cannot be called.
    Console.WriteLine("Unable to call the DoSomething method: {0}", e.Message)
End Try

Remarks

If the class name is not specified when the object is constructed, the default text string inherited from the base class is returned.

This property overrides Message. The error message should be localized.
