TaskHost.Properties 属性

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

获取包含与任务关联的属性的 DtsProperties 集合。

public:
 property Microsoft::SqlServer::Dts::Runtime::DtsProperties ^ Properties { Microsoft::SqlServer::Dts::Runtime::DtsProperties ^ get(); };

public Microsoft.SqlServer.Dts.Runtime.DtsProperties Properties { get; }

member this.Properties : Microsoft.SqlServer.Dts.Runtime.DtsProperties

Public ReadOnly Property Properties As DtsProperties

属性值

DtsProperties

一个 DtsProperties 集合。

实现

Properties

示例

下面的代码示例创建一个 XMLTask。 Properties使用集合时，将设置任务的属性。 Properties建议使用集合在任何任务上设置属性。 不建议将任务强制转换为其等效类和直接设置的属性。
