我正在尝试使用以下代码显示PluginManagerView的实例。
此XAML文件位于同一名称空间中,位于同一项目中。但是我在mainwindow.Show();
的行中发现错误
Error 1 'PluginManager.PluginManagerView' does not contain a definition for 'Show' and no extension method 'Show' accepting a first argument of type 'PluginManager.PluginManagerView' could be found (are you missing a using directive or an assembly reference?) Blah procedyre .cs 30 24 PluginManager
谁能告诉我这个问题是什么?为什么不为MainWindow的先前用法抛出错误?
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Windows;
using System.ComponentModel.Composition.Hosting;
namespace PluginManager
{
public class PublicProcedures : Application
{
public static void ShowPlugins()
{
var mainwindow = new PluginManagerView();
//An aggregate catalog that combines multiple catalogs
var catalog = new AggregateCatalog();
//Adds all the parts found in the same assembly as the Program class
//catalog.Catalogs.Add(new AssemblyCatalog(this.GetType().Assembly));
catalog.Catalogs.Add(new DirectoryCatalog("./Plugins/"));
var container = new CompositionContainer(catalog);
var modules = container.GetExportedValues<IPlugin>();
mainwindow.DataContext = modules;
mainwindow.Show();
}
}
}

为了调用Window.Show(我猜你想做什么),PluginManagerView必须从类Window派生,而它的XAML必须看起来像这样:< / p>
<Window x:Class="PluginManager.PluginManagerView" ...>
...
</Window>

抱怨无论PluginManagerView
是什么,它都没有Show
方法(您试图在名为“mainwindow”的PluginManagerView
实例中调用)。
