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\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);
// 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();
}
