示例

The following example loads a package, and then retrieves several package properties, including the CheckpointFileName.

Class PackageTest
    {
        static void Main(string[] args)
        {
            // The variable pkg points to the ___location of the
            // ExecuteProcess package sample
            // installed with the samples.
            string pkg = @"C:\Program Files\Microsoft SQL Server\90\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx";
            
            Application app = new Application();
            Package p = app.LoadPackage(pkg, null);
    
            // Once the package is loaded, this sample can
           // query on several properties
            long cc = p.CertificateContext;
            string cfn = p.CheckpointFileName;
            DTSProtectionLevel pl = p.ProtectionLevel;
            DTSPackageType dpt = p.PackageType;

            Console.WriteLine("CertificateContext = " + cc);
            Console.WriteLine("CheckpointFileName = " + cfn);
            Console.WriteLine("ProtectionLevel = " + pl);
            Console.WriteLine("PackageType = " + dpt);
        }
    }

Class PackageTest
    {
        Shared  Sub Main(ByVal args() As String)
            ' The variable pkg points to the ___location of the
            ' ExecuteProcess package sample
            ' installed with the samples.
            Dim pkg As String =  "C:\Program Files\Microsoft SQL Server\90\Samples\Integration Services\Package Samples\ExecuteProcess Sample\ExecuteProcess\UsingExecuteProcess.dtsx" 
 
            Dim app As Application =  New Application() 
            Dim p As Package =  app.LoadPackage(pkg,Nothing) 
 
            ' Once the package is loaded, this sample can
           ' query on several properties
            Dim cc As Long =  p.CertificateContext 
            Dim cfn As String =  p.CheckpointFileName 
            Dim pl As DTSProtectionLevel =  p.ProtectionLevel 
            Dim dpt As DTSPackageType =  p.PackageType 
 
            Console.WriteLine("CertificateContext = " + cc)
            Console.WriteLine("CheckpointFileName = " + cfn)
            Console.WriteLine("ProtectionLevel = " + pl)
            Console.WriteLine("PackageType = " + dpt)
        End Sub
    }

Sample Output:

CertificateContext = 0

CheckpointFileName =

ProtectionLevel = EncryptSensitiveWithUserKey

PackageType = Default
