An object that contains the numeric index or identity of the object in the collection.

Return Value

Type: System.Boolean
A Boolean that indicates whether items can be retrieved using indexing. A value of true indicates that the syntax LogProviders[x] can be used without throwing an exception. A value of false indicates that indexing cannot be used to retrieve items from the LogProviders collection.

If a log provider is added using the Add method, the Name of the log provider defaults to a GUID.

The following code sample uses 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 LogProviders_Tests
    class Program
        static void Main(string[] args)
            // The package is one of the SSIS Samples.
            string mySample = @"C:\Program Files\Microsoft SQL Server\100\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);
            LogProviders logProvs = pkg.LogProviders;

            // Search for the "SSIS log provider for Text files"
            // in the collection
            if (logProvs.Contains("SSIS log provider for Text files"))
                Console.WriteLine("The collection contains {0} provider", logProvs[0].CreationName);
                Console.WriteLine("The collection does not contain the SSIS log provider for Text files");

Sample Output:

The collection contains DTS.LogProviderTextFile.2 provider
