如何设置断点并使代码停止在 AttachedCommand 内的一行上？

在我的XAML中，我有这个命令（这是我从http://marlongrech.wordpress.com):

<TextBlock Text="Edit Test Customer">
    <Commands:CommandBehaviorCollection.Behaviors>
        <Commands:BehaviorBinding Event="MouseLeftButtonDown" 
                                   Command="{Binding ClickEditTestCustomer}"/>
    </Commands:CommandBehaviorCollection.Behaviors>
</TextBlock>

然后在命令中，如果我在里面设置一个断点 ExecuteDelegate 代码，例如在“layoutManger...”行上，即使执行了该代码，它也不会在断点处停止（我看到了我的视图）：

ClickEditTestCustomer = new SimpleCommand
{
    ExecuteDelegate = parameterValue =>
    {
        LayoutManager layoutManager = container.Resolve<LayoutManager>();
        layoutManager.DisplayViewAsPane("EditCustomer", "Edit Customer", new EditCustomerView());
    }
};

我该如何设置断点并使代码停止在 AttachedCommand 内的一行上？

In my XAML I have this command (which is an AttachedCommand which I got from http://marlongrech.wordpress.com):

<TextBlock Text="Edit Test Customer">
    <Commands:CommandBehaviorCollection.Behaviors>
        <Commands:BehaviorBinding Event="MouseLeftButtonDown" 
                                   Command="{Binding ClickEditTestCustomer}"/>
    </Commands:CommandBehaviorCollection.Behaviors>
</TextBlock>

Then in the command, if I set a breakpoint inside the ExecuteDelegate code, e.g. on "the "layoutManger..." line, it doesn't stop on the breakpoint even though that code is executed (I see my view):

ClickEditTestCustomer = new SimpleCommand
{
    ExecuteDelegate = parameterValue =>
    {
        LayoutManager layoutManager = container.Resolve<LayoutManager>();
        layoutManager.DisplayViewAsPane("EditCustomer", "Edit Customer", new EditCustomerView());
    }
};

How can I set a breakpoint and have the code stop on a line inside an AttachedCommand?

这应该没有任何问题。如果您 100% 确定 LayoutManager 行实际上正在运行，那么可能是我的代码 (JMC) 的调试功能有问题。尝试禁用 JMC 并再次运行场景

答案是我在两次中无意中复制了事件处理程序ClickEditTestCustomer，令人惊讶的是，它没有产生错误，并且只安静地执行了第二个实例：

ClickEditTestCustomer = new SimpleCommand
{
    ExecuteDelegate = parameterValue =>
    {
        LayoutManager layoutManager = container.Resolve<LayoutManager>();
        layoutManager.DisplayViewAsPane("EditCustomer", "Edit Customer", new EditCustomerView());
    }
};

ClickEditTestCustomer = new SimpleCommand
{
    ExecuteDelegate = parameterValue =>
    {
        LayoutManager layoutManager = container.Resolve<LayoutManager>();
        layoutManager.DisplayViewAsPane("EditCustomer", "Edit Customer", new EditCustomerView());
    }
};

The answer was that I had inadvertently copied in the event handler ClickEditTestCustomer in twice, which surprisingly didn't produce an error and quietly executed only the second instance:

ClickEditTestCustomer = new SimpleCommand
{
    ExecuteDelegate = parameterValue =>
    {
        LayoutManager layoutManager = container.Resolve<LayoutManager>();
        layoutManager.DisplayViewAsPane("EditCustomer", "Edit Customer", new EditCustomerView());
    }
};

ClickEditTestCustomer = new SimpleCommand
{
    ExecuteDelegate = parameterValue =>
    {
        LayoutManager layoutManager = container.Resolve<LayoutManager>();
        layoutManager.DisplayViewAsPane("EditCustomer", "Edit Customer", new EditCustomerView());
    }
};
