Wpf RouteEvent名称已被使用

在WPF中，我创建了3个用户控件“用户配置”、“系统配置”和“帐户配置”。所有这些用户控件都有“保存”和“取消”按钮。单击这些按钮，它们将引发在各自的类中声明和定义的路由事件。单击保存按钮时引发“ConfigurationSaved”事件，单击取消按钮时引发“ConfigurationCancelled”事件

引发这些事件时，承载用户控件的容器将负责保存配置

所有类的路由事件定义的代码段如下所示：

帐户配置视图：

public partial class AccountConfigurationView : UserControl

    static AccountConfigurationView()

        ConfigurationSavedEvent = EventManager.RegisterRoutedEvent("ConfigurationSaved",

        ConfigurationClosedEvent = EventManager.RegisterRoutedEvent("ConfigurationClosed",
        RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(AccountConfigurationView));

当我使用这些类时，我会收到TypeInitializationException，并显示以下消息：

已使用所有者类型“baskcode.Admin.Controls.AccountConfigurationView”的RoutedEvent名称“ConfigurationSaved”

如果我尝试加载任何其他控件，则会引发相同的异常。我无法纠正这个问题。请在这方面帮助我

我正在使用.Net版本4

谢谢。

我假设您多次初始化控件。不能多次注册同一路由事件名称

试试这个（对于一个

RoutedEvent

）：

这（对于多个实例）：在您的情况下

using System.Linq;

...

RoutedEvent[] x = EventManager.GetRoutedEvents();

if(!x.Contains(ConfigurationSaved)) {
    ConfigurationSavedEvent = EventManager.RegisterRoutedEvent(
        "ConfigurationSaved",
        RoutingStrategy.Bubble,
        typeof(RoutedEventHandler), 
        typeof(UserConfigurationView)
    );
}

检查EventManager.RegisterRoutedEvent参数。如果您从另一个文件复制并粘贴了它，很容易忘记更改所有者类型。例如：

public class UserControlA
{
  public static readonly RoutedEvent ClickEvent =
    EventManager.RegisterRoutedEvent(
      "Click",
      RoutingStrategy.Bubble,
      typeof(RoutedEventHandler),
      typeof(UserControlA));
}

但是你可以复制粘贴到另一个文件。注意下面错误的typeof（UserControlA），应该是typeof（UserControlB）

public class UserControlB
{
  public static readonly RoutedEvent ClickEvent =
    EventManager.RegisterRoutedEvent(
      "Click",
      RoutingStrategy.Bubble,
      typeof(RoutedEventHandler),
      typeof(UserControlA));
}
