ForLoop.Properties 속성

정의

네임스페이스:

Microsoft.SqlServer.Dts.Runtime

어셈블리:

Microsoft.SqlServer.ManagedDTS.dll

ForLoop에 대한 속성 집합을 DtsProperties 컬렉션으로 반환합니다.

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

속성 값

DtsProperties

DtsProperties 컬렉션입니다.

구현

Properties

설명

다음 코드 예제에서는 ForLoop 3개의 식 속성을 만들고 설정합니다. 속성을 ForLoop 설정하는 데 사용할 수 있는 Properties 컬렉션도 포함되어 있습니다. DescriptionForLoop 이 Name 구문을 사용하여 설정됩니다.
