Question

要求：将大量数据（OU中的所有用户）从活动目录中提取到数据库表中。

方法：我的任务是使用SSIS来完成这项任务，因为还有其他项目要作为标准ETL事项的同一个夜间任务的一部分来完成，所以这只是流程中的另一个步骤。

代码：

/*
Microsoft SQL Server Integration Services Script Task
Write scripts using Microsoft Visual C# 2008.
The ScriptMain is the entry point class of the script.
*/

using System;
using System.Data;
using System.Data.SqlClient;
using System.DirectoryServices;
using Microsoft.SqlServer.Dts.Runtime;
using System.Windows.Forms;

namespace ST_dc256a9b209442c7bc089d333507abeb.csproj
{
    [System.AddIn.AddIn("ScriptMain", Version = "1.0", Publisher = "", Description = "")]
    public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
    {

        #region VSTA generated code
        enum ScriptResults
        {
            Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success,
            Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
        };
        #endregion

        /*
        The execution engine calls this method when the task executes.
        To access the object model, use the Dts property. Connections, variables, events,
        and logging features are available as members of the Dts property as shown in the following examples.

        To reference a variable, call Dts.Variables["MyCaseSensitiveVariableName"].Value;
        To post a log entry, call Dts.Log("This is my log text", 999, null);
        To fire an event, call Dts.Events.FireInformation(99, "test", "hit the help message", "", 0, true);

        To use the connections collection use something like the following:
        ConnectionManager cm = Dts.Connections.Add("OLEDB");
        cm.ConnectionString = "Data Source=localhost;Initial Catalog=AdventureWorks;Provider=SQLNCLI10;Integrated Security=SSPI;Auto Translate=False;";

        Before returning from this method, set the value of Dts.TaskResult to indicate success or failure.

                    string email = results.Properties["mail"][0].ToString();

                    //Replace any single quotes in the string with two single quotes for sql INSERT statement

我希望你们中的很多人都会认识到这与数据女王的这篇文章中的代码基本相同：http://dataqueen.unlimitedviz.com/2012/09/get-around-active-directory-paging-on-ssis-import/我已经适应了我的目的，因为我遇到了很多问题我自己编写的代码。

目前，这是一个脚本任务。是的，我已在相关参考文献中添加，因此它们就在那里。

问题：当我在SSIS中运行脚本任务时（为了避免包的其他部分干扰任何机会）我得到：

Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
at System.Collections.ArrayList.get_Item(Int32 index)
at System.DirectoryServices.ResultPropertyValueCollection.get_Item(Int32 index)
at ST_dc256a9b209442c7bc089d333507abeb.csproj.ScriptMain.Main()

请任何人，任何想法?????????

所有归功于@billinkc（billinkc - 如果你添加一个答案，我会接受它而不是这个但我不喜欢留下问题，所以现在添加你的答案，因为你没有在最后添加答案周）

“我的猜测是失败的行是字符串employeeID = results.Properties [”employeeID“] [0] .ToString（）;因为你可能会得到像服务帐户这样没有定义employeeID的东西。复制你的将代码编入适当的.NET项目（我喜欢控制台），然后逐步使用deubgger查找行号。 - billinkc“
