ConnectionManager.SupportsDTCTransactions 属性

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

返回一个布尔值，该值指示连接是否支持 Microsoft 分布式事务处理协调器 (MS DTC) 事务。

public:
 property bool SupportsDTCTransactions { bool get(); };

[Microsoft.SqlServer.Dts.Runtime.Localization.LocalizablePropertyDescription(typeof(Microsoft.SqlServer.Dts.Runtime.Localized), "SupportsDTCTransactionsDesc")]
public bool SupportsDTCTransactions { get; }

[<Microsoft.SqlServer.Dts.Runtime.Localization.LocalizablePropertyDescription(typeof(Microsoft.SqlServer.Dts.Runtime.Localized), "SupportsDTCTransactionsDesc")>]
member this.SupportsDTCTransactions : bool

Public ReadOnly Property SupportsDTCTransactions As Boolean

属性值

Boolean

如果连接支持 MS DTC 事务，则为 true;否则为 false。

属性

LocalizablePropertyDescriptionAttribute

示例

下面的代码示例加载具有两个连接的现有包。 它会循环访问包中的连接管理器，并输出各种属性（包括 Boolean） SupportsDTCTransactions的值。
