member this.Contains : obj -> bool

Public Function Contains (index As Object) As Boolean

Parameters

index: Object

The name, description, ID, or index of the LogEntryInfo object to find in the collection.

Returns

Boolean

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.

Examples

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();  
        }  
    }  
}

            Dim app As Application =  New Application()   
            Dim pkg As Package =  app.LoadPackage(mySample,Nothing)

            Dim logDiagnostic As Boolean =  logInfos.Contains("Diagnostic")
