声明：

ItemsSource="{Binding Source={StaticResource TTColumn}, Path=Names}"

给出错误：

无法解析资源TTColumn。

整个.xaml代码是：

以下是我尝试绑定到WPF的Names变量的定义。

namespace XLTT.Core.Models
{
    public class TTColumn
    {
        private static string[] names = {"one", "two", "three"};   // the name field
        public static string[] Names   // the Name property
        {
            get 
            {
                return names; 
            }
            set 
            {
                names = value;
            }
        }
    }
}

Answer 1

如果要将控件绑定到静态属性，则应使用@include linear-gradient(hotpink, tomato); markup extension而不是x:Static（因为TTColumn不是静态资源）。

因此，您必须在MetroWindow xaml中添加对命名空间的引用：

StaticResource

然后用以下内容替换你的绑定：

<controls:MetroWindow x:Class="XLTT.Views.RemoveColumn"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             ...
             xmlns:models="clr-namespace:XLTT.Core.Models"

我希望这可以帮到你。

Answer 2

您需要为XLTT.Core.Models定义XAML命名空间，并在StaticResource扩展名中引用它。为此，我们需要知道声明命名空间的程序集名称 - ill将其称为SampleNamespace

首先将名称空间添加到MetroWindow元素。

<controls:MetroWindow x:Class="XLTT.Views.RemoveColumn"
             xmlns:models="clr-namespace:XLTT.Core.Models;assembly=SampleNamespace"

现在引用绑定中的命名空间。

ItemsSource="{Binding Source={StaticResource models:TTColumn}, Path=Names}"

无法将WPF控件成功绑定到C＃变量。资源无法解析
