DtsContainer.DelayValidation 属性

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

获得或设置一个布尔值，指示任务验证是否延迟到运行时。 默认值为 false。

public:
 property bool DelayValidation { bool get(); void set(bool value); };

[Microsoft.SqlServer.Dts.Runtime.Localization.LocalizablePropertyCategory(typeof(Microsoft.SqlServer.Dts.Runtime.Localized), "PropertyCategoryExecution")]
[Microsoft.SqlServer.Dts.Runtime.Localization.LocalizablePropertyDescription(typeof(Microsoft.SqlServer.Dts.Runtime.Localized), "DelayValidationDesc")]
public bool DelayValidation { get; set; }

[<Microsoft.SqlServer.Dts.Runtime.Localization.LocalizablePropertyCategory(typeof(Microsoft.SqlServer.Dts.Runtime.Localized), "PropertyCategoryExecution")>]
[<Microsoft.SqlServer.Dts.Runtime.Localization.LocalizablePropertyDescription(typeof(Microsoft.SqlServer.Dts.Runtime.Localized), "DelayValidationDesc")>]
member this.DelayValidation : bool with get, set

Public Property DelayValidation As Boolean

属性值

Boolean

如果包验证延迟到运行时，则为真。 如果包被验证，则为false，且在包实际执行前返回错误和警告。 false 可能阻止包运行，如果出现超出 MaximumErrorCount 属性的错误或警告。

属性

LocalizablePropertyCategoryAttribute LocalizablePropertyDescriptionAttribute

示例

该Package类通过继承EventsProvider实现 。DtsContainer 以下代码示例创建一个包，然后显示并设置继承自 DtsContainer的值。

using System;  
using System.Collections.Generic;  
using System.Text;  
using Microsoft.SqlServer.Dts.Runtime;  

namespace Microsoft.SqlServer.SSIS.Samples  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            // The package is the ExecuteProcess package sample   
            // that is installed with the SSIS samples.  
            string pkg = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx";  

            Application app = new Application();  
            Package p1 = app.LoadPackage(pkg, null);  

            // Show the properties inherited from DtsContainer.  
            Console.WriteLine("CreationName:    {0}", p1.CreationName);  
            Console.WriteLine("DebugMode:       {0}", p1.DebugMode);  
            Console.WriteLine("DelayValidation: {0}", p1.DelayValidation);  
            Console.WriteLine("Description:     {0}", p1.Description);  
            Console.WriteLine("Disable:         {0}", p1.Disable);  

            // Description is not set for this sample, so set it.  
            p1.Description = "This is the Execute Process Package Sample";  
            Console.WriteLine("Description after modification: {0}", p1.Description);  

            Console.WriteLine();  
        }  
    }  
}  

Imports System  
Imports System.Collections.Generic  
Imports System.Text  
Imports Microsoft.SqlServer.Dts.Runtime  

Namespace Microsoft.SqlServer.SSIS.Samples  
    Class Program  
        Shared  Sub Main(ByVal args() As String)  
            ' The package is the ExecuteProcess package sample   
            ' that is installed with the SSIS samples.  
            Dim pkg As String =  "C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx"   

            Dim app As Application =  New Application()   
            Dim p1 As Package =  app.LoadPackage(pkg,Nothing)   

            ' Show the properties inherited from DtsContainer.  
            Console.WriteLine("CreationName:    {0}", p1.CreationName)  
            Console.WriteLine("DebugMode:       {0}", p1.DebugMode)  
            Console.WriteLine("DelayValidation: {0}", p1.DelayValidation)  
            Console.WriteLine("Description:     {0}", p1.Description)  
            Console.WriteLine("Disable:         {0}", p1.Disable)  

            ' Description is not set for this sample, so set it.  
            p1.Description = "This is the Execute Process Package Sample"  
            Console.WriteLine("Description after modification: {0}", p1.Description)  

            Console.WriteLine()  
        End Sub  
    End Class  
End Namespace  

示例输出：

Creation名称：MSDTS。Package.1

调试模式：错误

延迟验证：正确

说明:

禁用：错误

修改后的描述：这是执行进程包示例

注解

在软件包运行前验证是一种在执行开始前发现错误的方法。 不过，它会处理包以发现错误，如果没有发现错误，包就会运行。 由于验证过程会增加包裹的处理量，因此应仅在必要时使用。
