这是从咱们网站上找到的代码，先记录一下：
public partial class Page : UserControl{ public Page() { InitializeComponent(); }//点击加载按钮事件 void OnClick(object sender, EventArgs args) { //获取要加载的dll文件信息 string assembly = txtPlugIn.Text; WebClient client = new WebClient(); //准备获取dll文件的信息 client.OpenReadCompleted += OnReadCompleted; client.OpenReadAsync(new Uri(assembly, UriKind.Relative)); } void OnReadCompleted(object sender, OpenReadCompletedEventArgs e) { AssemblyPart part = new AssemblyPart(); //获取加载的dll信息(stream格式) Assembly assembly = part.Load(e.Result);//构造该对象（插件）的实例 IEditText editor = assembly.CreateInstance("Implementation.Editor") as IEditText; if (editor != null) { //加载其中的控件（gridHosting类型为<Grid>） gridHosting.Children.Add(editor.GetControls()); editor.SetText(txtToEdit.Text); //完成事件绑定 editor.TextChanged += OnTextChanged; } } //内容更新 void OnTextChanged(object sender, Interfaces.TextChangedEventArgs e) { txtToEdit.Text = e.Text; }}
