MOSS 对象模型的简单开发ＤＥＭＯ

这几天很忙，但是每天打开ＱＱ，还是ＭＳＮ，ＥＭＬ关于ＭＯＳＳ开发的问题确实不少，但我看拉下，确实很简单的问题，都是关于一些对象模型的运用，可能大家很少看ＳＤＫ，里面介绍的很明白噢。
下面介绍一下ＭＯＳＳ对象模型的简单介绍，希望那些才接触ＭＯＳＳ的同仁们，快点入门，希望大家共同进步。
protected void GetSitesAndGroups()
{
    string userList = SPEncode.HtmlEncode(TextBox1.Text) +
        " is a user in the following webs:<BR>";

    SPSite mySite = SPContext.Current.Site;
    SPWebCollection allWebs = mySite.AllWebs;

    foreach (SPWeb subWeb in allWebs)
    {
        string listGroups = "";

        /*Use AllUsers not Users to ensure you find the user*/
        SPUserCollection allUsers = subWeb.AllUsers;
        foreach (SPUser user in allUsers)
        {
            if (user.LoginName.ToUpper() == TextBox1.Text.ToUpper())
            {
                SPGroupCollection allGroups = user.Groups;
                foreach (SPGroup group in allGroups)
                {
                    listGroups += SPEncode.HtmlEncode(group.Name) + "  ";
                }
                userList += subWeb.ServerRelativeUrl.ToString() +
