我有一个类“DataLib.cs”和一个UserControl“MediumTile.xaml”。如果我通过以下代码在DataLib.cs中使用UserControl：
var TestTile = new MediumTile();
TestTile.Measure(new Size(336, 336));
TestTile.Arrange(new Rect(0, 0, 336, 336));
我收到此错误：
“System.Windows.ni.dll中出现”System.Windows.Markup.XamlParseException“类型的异常（第一次机会）。”
带有“MediumTile.g.cs”的这一行的标记：
System.Windows.Application.LoadComponent(this, new System.Uri("/DataLib;component/MediumTile.xaml", System.UriKind.Relative));
看起来像InitializeComponent（）中有问题;并且实际上不存在目录“component”。
MediumTile.xaml：

试试这个：

路径宽度为180后，您有space。
