System.TypeLoadException无法找到Windows运行时类型“Windows.Foundation”异常 [英] System.TypeLoadException Could not find Windows Runtime type 'Windows.Foundation' exception

问题描述

在我的Windows Phone 8.1应用程序中，我正在创建一个CustomPage，然后导航到它，所有代码都在后面。我的CustomPage类是：

使用Windows.UI.Xaml.Controls; 
 
命名空间TestApp {
公共类CustomPage：Page {
 public CustomPage（）{
 this.BuildPage（）; 
} 
 
 private void BuildPage（）{
 var panel = new StackPanel（）; 
 panel.Children.Add（new TextBlock {Text =Hello World}）; 
 this.Content = panel; 
} 
} 
} 

然后在我的MainPage.xaml.cs中我这样做：

 CustomPage myNewPage = new CustomPage（）; 
 Frame.Navigate（myNewPage.GetType（））; 

但是这会引发System.TypeLoadException异常 - 找不到Windows运行时类型'Windows.Foundation'

如果我不做一个CustomPage类只是一个Page类，它工作正常，但我需要创建一个CustomPage类，我怎么能解决这个问题？

解决方案

您可以使用typeOf运算符来获取您的客户页面的类型，如下所示。

  typeof运算（myNewPage）; 

In my Windows Phone 8.1 app I'm creating a CustomPage and then navigating to it, all in code behind. My CustomPage class is:

using Windows.UI.Xaml.Controls;

namespace TestApp {
	public class CustomPage : Page {
		public CustomPage() {
			this.BuildPage();
		}

		private void BuildPage() {
			var panel = new StackPanel();
			panel.Children.Add(new TextBlock { Text = "Hello World" });
			this.Content = panel;
		}
	}
}

And then in my MainPage.xaml.cs I'm doing this:

CustomPage myNewPage = new CustomPage();
Frame.Navigate(myNewPage.GetType());

However this throws a System.TypeLoadException exception - Could not find Windows Runtime type 'Windows.Foundation'
If I don't do a CustomPage class just a Page class, it works fine, but I need to create a CustomPage class, how could I solve this?

解决方案

You can use typeOf operator for getting the type of your custome page like below.

typeof(myNewPage);
