WorkflowDesignerLoader.SaveDesignerLayout Methode

Definition

Namespace:

System.Workflow.ComponentModel.Design

Assembly:

System.Workflow.ComponentModel.dll

Serialisiert das Designerlayout.

protected:
 void SaveDesignerLayout(System::Xml::XmlWriter ^ layoutWriter, System::Workflow::ComponentModel::Design::ActivityDesigner ^ rootDesigner, [Runtime::InteropServices::Out] System::Collections::IList ^ % layoutSaveErrors);

protected void SaveDesignerLayout (System.Xml.XmlWriter layoutWriter, System.Workflow.ComponentModel.Design.ActivityDesigner rootDesigner, out System.Collections.IList layoutSaveErrors);

member this.SaveDesignerLayout : System.Xml.XmlWriter * System.Workflow.ComponentModel.Design.ActivityDesigner * IList -> unit

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

Parameter

layoutWriter

XmlWriter

XmlWriter, der zum Serialisieren des Layouts verwendet wird.

rootDesigner

ActivityDesigner

Stammaktivität, aus der die Layoutinformationen abgerufen werden.

layoutSaveErrors

IList

Während der Serialisierung aufgetretene Fehler.

Beispiele

Im folgenden Beispiel wird veranschaulicht, wie die Entwurfslayoutinformationen eines Workflows mithilfe der SaveDesignerLayout-Methode gespeichert werden. Nachdem das XmlWriter Objekt erstellt wurde, wird das ActivityDesigner für den RootComponent des Workflows abgerufen und an die SaveDesignerLayout -Methode übergeben. Informationen zum Laden der durch diese Methode generierten Layoutdatei finden Sie unter 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
