示例

下面的代码示例设置 CheckpointUsage 属性。

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

namespace Package_API  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
                    Application app = new Application();  
            Package pkg = new Package();  
            pkg = app.LoadPackage(@"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx", null);  

            // Set the CheckpointUsage to IfExistts to force package to retart if  
            // the file specified by the CheckpointFileName property is found.  
            pkg.CheckpointUsage = DTSCheckpointUsage.IfExists;  

            Console.WriteLine("Check for existing checkpoint file? {0}", pkg.CheckpointUsage);  
        }  
    }  
}

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

Namespace Package_API  
    Class Program  
        Shared  Sub Main(ByVal args() As String)  
                    Dim app As Application =  New Application()   
            Dim pkg As Package =  New Package()   
            pkg = app.LoadPackage("C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx", Nothing)  

            ' Set the CheckpointUsage to IfExistts to force package to retart if  
            ' the file specified by the CheckpointFileName property is found.  
            pkg.CheckpointUsage = DTSCheckpointUsage.IfExists  

            Console.WriteLine("Check for existing checkpoint file? {0}", pkg.CheckpointUsage)  
        End Sub  
    End Class  
End Namespace

示例输出：

Check for existing checkpoint file? IfExists

注解

此属性的默认值为 Never，指示无法重启包。关于包中检查点的使用，请参见 “使用检查点重启包”。
