WorkflowDesignerLoader.SaveDesignerLayout 方法

定義

命名空間:

System.Workflow.ComponentModel.Design

組件:

System.Workflow.ComponentModel.dll

將設計工具配置序列化。

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)

參數

layoutWriter

XmlWriter

用來序列化配置的 XmlWriter。

rootDesigner

ActivityDesigner

從中取得配置資訊的根活動。

layoutSaveErrors

IList

序列化期間遇到的錯誤。

範例

下列範例示範如何使用 SaveDesignerLayout 方法儲存工作流程的設計配置資訊。 XmlWriter建立 物件之後， ActivityDesignerRootComponent 會擷取工作流程的 ，並傳遞至 SaveDesignerLayout 方法。 若要載入由這個方法產生的配置檔案，請參閱 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
