XFC0045 绑定(bind):在“Page_Navigation.ViewModels.ThirdPageViewModel”上找不到属性“Tittle”。从该区域获取错误 - Page_Navigation\Views\ThirdPage.xaml

using Xamarin.Forms;

namespace Page_Navigation.ViewModels
{
    public class ThirdPageViewModel : BindableObject
    {
        public ObservableCollection<Matches> MatchesList { get; set; }
        
        public ThirdPageViewModel()
        {
            MatchesList = new ObservableCollection<Matches>();
            MatchesList.Add(new Matches { Tittle = "Tittle 1", Description = "Description 1" });
            MatchesList.Add(new Matches { Tittle = "Tittle 2", Description = "Description 2" });
            MatchesList.Add(new Matches { Tittle = "Tittle 3", Description = "Description 3" });
            MatchesList.Add(new Matches { Tittle = "Tittle 4", Description = "Description 4" });
        }
    }

    public class Matches
    {
        public string Tittle { get; set; }
        public string Description { get; set; }
    }
}

                        </Grid>

                </DataTemplate>
                
            </ListView.ItemTemplate>
        </ListView>
    </ContentPage.Content>
</ContentPage>

I don't know why this exception. I am using VS2019 and Xamarin.forms 4.8.0.1451

最佳答案

您必须删除 x:DataType 属性，因为它与编译绑定(bind)相关，并且您已经为 View 模型定义了 BindingContext。

在此处检查 XF 编译绑定(bind):Xamarin.Forms Compiled Bindings

关于c# - 使用 MVVM 绑定(bind) : Property not found in Xamarin. 表单，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/65791339/
