示例

The following code sample adds a log entry to the collection.

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;

            //Note how many log entries exist before adding one.
            String countLEI = logInfos.Count.ToString();
            Console.WriteLine("Entries at beginning: {0}", countLEI);
 
            String newName = "My new log entry info";
            String newDesc = "My new Description";
            DTSLogEntryFrequency newFreq = DTSLogEntryFrequency.Consistent;
            logInfos.Add(newName, newDesc, newFreq);

            //Note how many log entries exist after adding one.
            countLEI = logInfos.Count.ToString();
            Console.WriteLine("Entries after adding one: {0}", countLEI);

            //Now remove the entry just added.
            logInfos.Remove("My new log entry info");
            countLEI = logInfos.Count.ToString();
            Console.WriteLine("Entries after Remove: {0}", countLEI);
        }
    }
}

    Class Program

            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 
 
            'Note how many log entries exist before adding one.
            Dim countLEI As String =  logInfos.Count.ToString() 
            Console.WriteLine("Entries at beginning: {0}", countLEI)
 
            Dim NewName As String =  "My new log entry info" 
            Dim NewDesc As String =  "My new Description" 
            Dim NewFreq As DTSLogEnTryFrequency =  DTSLogEnTryFrequency.Consistent 
            logInfos.Add(NewName, NewDesc, NewFreq)
 
            'Note how many log entries exist after adding one.
            countLEI = logInfos.Count.ToString()
            Console.WriteLine("Entries after adding one: {0}", countLEI)
 
            'Now remove the entry just added.
            logInfos.Remove("My new log entry info")
            countLEI = logInfos.Count.ToString()
            Console.WriteLine("Entries after Remove: {0}", countLEI)
         End Sub
    End Class
End Namespace

Sample Output:

Entries at beginning: 1

Entries after adding one: 2

Entries after Remove: 1
