WPF 动态加载用户控件

//这里可以动态加载其他dll文件中的组件
Assembly assem = Assembly.LoadFile($"{Directory.GetCurrentDirectory()}\\{data.DllName}");
var onePage = assem.CreateInstance(data.ClassName);

ClosableTab theTabItem = new ClosableTab();
theTabItem.Content = onePage;
theTabItem.Title = data.Title;
myTabControl.Items.Add(theTabItem);
theTabItem.Focus();
