Rückgabewert

A Boolean that indicates whether the collection can be accessed by name, description, ID, or index. A value of true indicates that the collection can be accessed by using the syntax LogEntryInfos[index]. A value of false indicates that indexing cannot be used to retrieve items from the LogEntryInfos collection; using this property throws an exception.

Beispiel

The following code sample uses the Contains method to determine if a log entry with the name "Diagnostic" is in the collection. The method returns a Boolean.

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

namespace LogEntryInfosTest
{
    class Program
    {
        static void Main(string[] args)
        {
            // The package is one of the SSIS Samples.
            string mySample = @"C:\Program Files\Microsoft SQL Server\90\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx";

            // Create the Application, and load the sample.
            Application app = new Application();
            Package pkg = app.LoadPackage(mySample, null);

            // Get the LogEntryInfos from the package.
            LogEntryInfos logInfos = pkg.LogEntryInfos;

            //See if the collection contains a LogEntryInfo named "Diagnostic".
            Boolean logDiagnostic = logInfos.Contains("Diagnostic");
            Console.WriteLine("Contains Diagnostic? {0}", logDiagnostic);

            Console.WriteLine();
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace LogEnTryInfosTest
    Class Program
        Shared  Sub Main(ByVal args() As String)
            ' The package is one of the SSIS Samples.
            Dim mySample As String =  "C:\Program Files\Microsoft SQL Server\90\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx" 
 
            ' Create the Application, and load the sample.
            Dim app As Application =  New Application() 
            Dim pkg As Package =  app.LoadPackage(mySample,Nothing) 
 
            ' Get the LogEntryInfos from the package.
            Dim logInfos As LogEnTryInfos =  pkg.LogEnTryInfos 
 
            'See if the collection contains a LogEntryInfo named "Diagnostic".
            Dim logDiagnostic As Boolean =  logInfos.Contains("Diagnostic") 
            Console.WriteLine("Contains Diagnostic? {0}", logDiagnostic)
 
            Console.WriteLine()
        End Sub
    End Class
End Namespace

Sample Output:

Contains Diagnostic? True
