IfElseBranchActivity 构造函数

定义

命名空间:

System.Workflow.Activities

程序集:

System.Workflow.Activities.dll

初始化 IfElseBranchActivity 类的新实例。

重载

IfElseBranchActivity()	初始化 IfElseBranchActivity 类的新实例。
IfElseBranchActivity(String)	使用活动名初始化 IfElseBranchActivity 类的新实例。

IfElseBranchActivity()

初始化 IfElseBranchActivity 类的新实例。

public:
 IfElseBranchActivity();

public IfElseBranchActivity ();

Public Sub New ()

示例

下面的代码示例演示如何创建 IfElseBranchActivity 类的两个新实例。 此代码示例摘自 PurchaseOrder.cs 文件中的“补偿”SDK 示例。 有关详细信息，请参阅 “使用补偿”。

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

IfElseBranchActivity(String)

使用活动名初始化 IfElseBranchActivity 类的新实例。

public:
 IfElseBranchActivity(System::String ^ name);

public IfElseBranchActivity (string name);

new System.Workflow.Activities.IfElseBranchActivity : string -> System.Workflow.Activities.IfElseBranchActivity

Public Sub New (name As String)

参数

name

String

活动的用户定义名称。
