範例

下列程式碼範例示範此成員的使用。 在此範例中，事件處理常式會報告事件發生次數 Binding.BindingComplete 。 此報告可協助您瞭解事件發生的時間，並可協助您進行偵錯。 若要報告多個事件或經常發生的事件，請考慮將 取代 MessageBox.ShowConsole.WriteLine 為 或將訊息附加至多行 TextBox 。

若要執行範例程式碼，請將它貼到包含名為 Binding1 之型 Binding 別實例的專案。 然後，確定事件處理常式與事件相關聯 Binding.BindingComplete 。

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
