此示例演示如何初始化 Error 的 SuspendActivity 属性，以及在别处讨论的与此有关的其他概念。

此代码示例摘自 SuspendAndTerminateWorkflow.Designer.cs 文件中的“挂起和终止 SDK”示例。 有关详细信息，请参阅 使用挂起和终止。

[System.Diagnostics.DebuggerNonUserCode()]
private void InitializeComponent()
{
    this.CanModifyActivities = true;
    this.suspend = new System.Workflow.ComponentModel.SuspendActivity();
    this.consoleMessage = new System.Workflow.Activities.CodeActivity();
    this.terminate = new System.Workflow.ComponentModel.TerminateActivity();
    //
    // suspend
    //
    this.suspend.Error = null;
    this.suspend.Name = "suspend";
    //
    // ConsoleMessage
    //
    this.consoleMessage.Name = "consoleMessage";
    this.consoleMessage.ExecuteCode += new System.EventHandler(this.OnConsoleMessage);

    //
    this.terminate.Error = null;

    //
    // SuspendAndTerminateWorkflow
    //
    this.Activities.Add(this.suspend);
    this.Activities.Add(this.consoleMessage);
    this.Activities.Add(this.terminate);

    this.CanModifyActivities = false;
}
