Protected Sub SaveDesignerLayout (layoutWriter As XmlWriter, rootDesigner As ActivityDesigner, ByRef layoutSaveErrors As IList)

Parametri

layoutWriter

XmlWriter

XmlWriter in cui vengono serializzate le informazioni di layout.

rootDesigner

ActivityDesigner

L'attività radice da cui si ottengono le informazioni di layout.

layoutSaveErrors

IList

Errori verificatisi durante la serializzazione.

Esempio

Nell'esempio seguente viene illustrato come salvare le informazioni del layout della finestra di progettazione di un flusso di lavoro utilizzando il metodo SaveDesignerLayout. Dopo aver creato l'oggetto XmlWriter , l'oggetto ActivityDesigner per il RootComponent flusso di lavoro viene recuperato e passato al SaveDesignerLayout metodo . Per caricare il file del layout generato con questo metodo, vedere LoadDesignerLayout.

public void SaveLayout()
{
    using (XmlWriter writer = XmlWriter.Create("wfInstanceId.designer.xml"))
    {
        IList layoutSaveErrors = new ArrayList() as IList;
        IDesignerHost host = (IDesignerHost)GetService(typeof(IDesignerHost));
        ActivityDesigner rootDesigner = host.GetDesigner(host.RootComponent) as ActivityDesigner;
        this.SaveDesignerLayout(writer, rootDesigner, out layoutSaveErrors);

        if (layoutSaveErrors.Count > 0)
        {
            System.Text.StringBuilder sb = new System.Text.StringBuilder("Errors:\r\n");
            foreach (WorkflowMarkupSerializationException error in layoutSaveErrors)
            {
                sb.Append(error.Message + "\r\n");
            }
            MessageBox.Show(sb.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }
}

Public Sub SaveLayout()
    Using writer As XmlWriter = XmlWriter.Create("wfInstanceId.designer.xml")
        Dim layoutSaveErrors As IList = CType(New ArrayList(), IList)

        Dim host As IDesignerHost = CType(GetService(GetType(IDesignerHost)), IDesignerHost)
        Dim rootDesigner As ActivityDesigner = CType(host.GetDesigner(host.RootComponent), ActivityDesigner)
        Me.SaveDesignerLayout(writer, rootDesigner, layoutSaveErrors)

        If layoutSaveErrors.Count > 0 Then
            Dim sb As New System.Text.StringBuilder("Errors:\r\n")
            For Each errorMessage As WorkflowMarkupSerializationException In layoutSaveErrors
                sb.Append(errorMessage.Message + "\r\n")
            Next
            MessageBox.Show(sb.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
        End If
    End Using
End Sub
