A Boolean that indicates whether the collection can be accessed by name, identity, ID, or index.

A value of false indicates that indexing cannot be used to retrieve items from the LogProviderInfos collection; using this property throws an exception.

Beispiel

The following code sample uses the Contains method to determine if a log provider with the name "SSIS log provider for Text files" is in the collection. The method returns a Boolean.

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

namespace LogProvInfoProperties
{
    class Program
    {
        static void Main(string[] args)
        {
        Application app = new Application();
        LogProviderInfos infos = app.LogProviderInfos;

        //See if the collection contains a log provider
        // with the name "SSIS log provider for Text files".
        Boolean logText = infos.Contains("SSIS log provider for Text files");
        Console.WriteLine("Contains Text log provider? {0}", logText);
        }
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Text
Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace LogProvInfoProperties
    Class Program
        Shared  Sub Main(ByVal args() As String)
        Dim app As Application =  New Application() 
        Dim infos As LogProviderInfos =  app.LogProviderInfos 
 
        'See if the collection contains a log provider
        ' with the name "SSIS log provider for Text files".
        Dim logText As Boolean =  infos.Contains("SSIS log provider for Text files") 
        Console.WriteLine("Contains Text log provider? {0}", logText)
        End Sub
    End Class
End Namespace
