LogProvider.DelayValidation 属性

定义

获取或设置一个布尔值,该值指定是否将 Validate(IDTSInfoEvents) 日志提供程序的调用推迟到包执行时。

public:
 property bool DelayValidation { bool get(); void set(bool value); };
public bool DelayValidation { get; set; }
member this.DelayValidation : bool with get, set
Public Property DelayValidation As Boolean

属性值

Boolean

一个布尔值,指定是否将验证推迟到包执行时。 值为 true 指示验证延迟到执行包时。 默认值为 false。

示例

下面的代码示例加载启用了日志记录的包。 在加载包后,将 LogProviders 创建集合,并对集合中的每个日志提供程序进行枚举,并打印每个属性的值,包括 DelayValidation

示例输出:

ConfigString

CreationName DTS。Dts.logprovidertextfile。1

DelayValidation False

说明将事件的日志项写入 CSV 文件

HostType LogProvider

ID {1E107E39-DB79-4F02-B8A7-61D88F2DEF63}

InnerObject System.__ComObject

命名文本文件的 SSIS 日志提供程序

注解

此属性的值控制验证是否延迟,直到调用包的 Execute 方法。
