访问大量组列表的Web部件

web-parts sharepoint c#

创建我的Web部件是为了解决一个常见问题:用户必须单击太多次才能访问他们的项目。我有一个文档库,它有12个主要类别,下面有许多子文件夹。大多数情况下,每个子文件夹都相当于一个实际的SharePoint组。对于每个主类别,我都会得到一个包含所有子文件夹的数组,然后循环查看下面的代码中是否存在该组,我知道是什么使它变慢了。

有没有比每次都轮询整个组列表更容易查看组是否存在的方法?我可能会对这个名单进行大约650次的投票。

这是我的密码:

protected override void RenderWebPart(HtmlTextWriter output)
{
    try
    {
        #region Connect to the Current Site
        using (SPSite siteCollection = SPContext.Current.Site)
        {
            #region Connect to the tab we want to have this done on
            using (SPWeb oWebsite = siteCollection.OpenWeb("Downloads"))
            {
                #region Find all the items in the list
                foreach (SPListItem item in oWebsite.GetList(oWebsite.ServerRelativeUrl + "/My Files").GetItems(new SPQuery()))
                {
                    string type = Convert.ToString(item["Type"]);
                    string name = Convert.ToString(item["Name"]);

                    #region If this is a legit folder
                    if ((String.IsNullOrEmpty(type)) && (name != "Archived") && (name != "Other"))
                    {
                        #region Get all the sub folders for each main folder
                        foreach (SPFolder SFolder in item.Folder.SubFolders)
                        {
                            #region Then get a list of all groups in SharePoint
                            foreach (SPGroup part in oWebsite.Groups)
                            {
                                #region Then check to see if there is a group with the same name as the folder
                                if (SFolder.Name == part.Name)
                                {
                                    #region Then check to see if the user is in that group
                                    foreach (SPUser vUser in part.Users)
                                    {
                                        string redirectURL = oWebsite.Url + "/My FIles/" + item.Name + "/" + part.Name;

                                        }

                                        else if ((oWebsite.CurrentUser.ID == vUser.ID) && (!IsQueryStringNull) && (!IsOwner))

在网上找到这个。

public static bool GroupExists(SPGroupCollection groups, string name)
{
    if (string.IsNullOrEmpty(name) || (name.Length > 255) || (groups == null) || (groups.Count == 0))
    {
        return false;
    }
    else
    {
        return (groups.GetCollection(new String[] { name }).Count > 0);
    }
}

它看起来更有效,但我将无法测试这个,直到一个自动化过程在20分钟内完成。
