下面的代码示例使用名称作为索引从集合中删除项。
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;
//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);
}
}
