获取或设置由 ThrowActivity 调用的执行的类型。

public:
 property Type ^ FaultType { Type ^ get(); void set(Type ^ value); };

[System.ComponentModel.TypeConverter(typeof(System.Workflow.ComponentModel.ThrowActivity+FaultTypeConverter))]
public Type FaultType { get; set; }

[<System.ComponentModel.TypeConverter(typeof(System.Workflow.ComponentModel.ThrowActivity+FaultTypeConverter))>]
member this.FaultType : Type with get, set

Public Property FaultType As Type

属性值

Type

属性

TypeConverterAttribute

示例

下面的代码演示在工作流中使用单个引发活动来实现异常处理。 此示例演示如何将 FaultType 设置为 null。 此代码示例摘自 ThrowWorkflow.cs 文件中的“引发 SDK”示例。 有关详细信息，请参阅 使用引发。

    [System.Diagnostics.DebuggerNonUserCode()]

    {
        this.CanModifyActivities = true;

        this.throwActivity1 = new System.Workflow.ComponentModel.ThrowActivity();
        activitybind1.Name = "ThrowWorkflow";
        activitybind1.Path = "ThrownException";
        //

        this.throwActivity1.SetBinding(System.Workflow.ComponentModel.ThrowActivity.FaultProperty, ((System.Workflow.ComponentModel.ActivityBind)(activitybind1)));
        //
