示例

下面的代码示例演示了此成员的用法。 在此示例中，事件处理程序报告事件的发生情况 Binding.BindingComplete 。 此报表可帮助你了解事件发生的时间，并可以帮助你进行调试。 若要报告多个事件或频繁发生的事件，请考虑将 MessageBox.Show 替换为 Console.WriteLine 或将消息追加到多行 TextBox。

若要运行示例代码，请将其粘贴到包含名为 Binding1的 类型的Binding实例的项目中。 然后，确保事件处理程序与 Binding.BindingComplete 事件相关联。

private void Binding1_BindingComplete(Object sender, BindingCompleteEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Binding", e.Binding );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "BindingCompleteState", e.BindingCompleteState );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "BindingCompleteContext", e.BindingCompleteContext );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Exception", e.Exception );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Cancel", e.Cancel );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "BindingComplete Event" );
}

Private Sub Binding1_BindingComplete(sender as Object, e as BindingCompleteEventArgs) _ 
     Handles Binding1.BindingComplete

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Binding", e.Binding)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "BindingCompleteState", e.BindingCompleteState)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "BindingCompleteContext", e.BindingCompleteContext)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Exception", e.Exception)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Cancel", e.Cancel)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"BindingComplete Event")

End Sub

BindingCompleteState使用 确定绑定是否成功，或者发生了错误或异常。
