在xmlns clr-namespace中找不到Xamarin Forms throw异常:

时间:2016-12-05 20:51:58

标签: c# .net xaml xamarin xamarin.forms

我使用xamarin表单进行跨移动应用程序,但IList变量想显示Count然后抛出异常。

例外明细: Xamarin.Forms.Xaml.XamlParseException:位置19:64。键入在xmlns clr-namespace中找不到的PersonFactory:MHG.Sample.Model; assembly = MHG.Sample

PersonFactory.cs文件内容(此文件为.xaml数据工厂)

解决了这个问题; x:Static local: PersonFactory.People 删除空格本地:在PersonFactory关键字之间。 x:Static local:PersonFactory.People

在项目设置中验证“程序集名称”设置为MHG.Sample。

在Visual Studio中:右键单击共享(Portable)项目,然后单击“属性”。在“库”选项卡上应该有一个带有“程序集名称”标签的框。

OR

在Xamarin Studio中:右键单击共享项目(不是iOS或Android项目)并单击选项。在“输出”屏幕上应该有一个标签为“程序集名称”的框。

<ListView x:Name="LstPeople" ItemsSource="{ Binding . }" Footer="{ Binding Count, Source={ x:Static local: PersonFactory.People }">
