发生XamlParseException - 未实现方法或操作 [英] XamlParseException occurred -- The method or operation is not implemented

问题描述

我是WPF的新手，当我使用MVVM和Prism编写我的第一个WPF应用程序时，遇到异常，异常发生在以下代码中：

I'am a newer to WPF, when i use MVVM and Prism to write my first WPF application, i meet an exception, the exception happend from the below code:

的xmlns：I =" HTTP：//schemas.microsoft.com/expression/2010/interactivity"

xmlns：ei = http://schemas.microsoft.com/expression / 2010 / interaction

xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
xmlns:ei=http://schemas.microsoft.com/expression/2010/interactions

< Button Command =" {Binding}"含量="登录" Grid.Row = QUOT 1 QUOT; IsEnabled =" {Binding Path = IsLoginButtonEnabled}">

< i：Interaction.Triggers>

< i：EventTrigger EventName =" Click"> ; $
< ei：CallMethodAction TargetObject =" {Binding}"方法名= QUOT;为LoginEvent" /> -
此行有一个异常"发生了XamlParseException"该方法或操作未实施。

< / i：EventTrigger>

< / i：Interaction.Triggers>

< / Button>

<Button Command="{Binding }" Content="Login" Grid.Row="1" IsEnabled="{Binding Path=IsLoginButtonEnabled}">
<i:Interaction.Triggers>
<i:EventTrigger EventName="Click">
<ei:CallMethodAction TargetObject="{Binding}" MethodName="LoginEvent"/> -- This line have an exception "XamlParseException occurred" The method or operation is not implemented.
</i:EventTrigger>
</i:Interaction.Triggers>
</Button>

我使用Prism和MEF将viewmodel注入此视图，并使用"LoginEvent"和"LoginEvent"。存在于viewmodel类中LoginViewModel

I use Prism and MEF to inject viewmodel to this view, and the "LoginEvent" is exists in viewmodel class LoginViewModel

public void Login（）

{

//无事可做。

public void Login()
{
//Nothing to do.

}

非常奇怪的是，我甚至无法使用try ... catch ...在LoginView.cs文件中捕获此异常：

the very strange thing is that i can not even use try ... catch... to catch this exception like this in the LoginView.cs file:

尝试
{

InitializeComponent（）;

}

catch（例外e）

{

InitializeComponent();
}
catch (Exception e)
{

}

以前有没有人见过这个，等你的帮助!!!!

Is there anybody met this before, waitting for your help!!!!

Hi Itigoo,
