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)
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
namespace MHG.Sample.Model
{
public static class PersonFactory
{
public static List<Person> People = new List<Person>();
static PersonFactory()
{
var list = new ObservableCollection<Person>();
for (var i = 0; i < new Random().Next(10, 100); i++)
{
var person = new Person(i, Faker.Name.First(), Faker.Name.Last(), $"{new Random().Next(1, 10)}.jpg")
{
Description = Faker.Lorem.Sentence()
};
list.Add(person);
}
People.AddRange(list);
}
}
}

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
答案 0 :(得分:2)
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 }">
