SharePoint determines whether the user is in the field & quot; personnel and Group & quot;. The sharepoint Field

SharePoint determines whether the user is in the field "personnel and group", sharepoint Field

These two methods are recorded for future use;

1. Determine whether the user is in the field personnel and group;

    public static bool IsUserInFiled(int UserID, string ListName, int ItemID, string FieldInterName)        {            bool value = false;            try            {                using (SPSite site = new SPSite(SITERUL))                {                    using (SPWeb web = site.OpenWeb())                    {                        SPList list = web.Lists.TryGetList(ListName);                        SPListItem item = list.GetItemById(ItemID);                        string dispName = list.Fields.GetFieldByInternalName(FieldInterName).Title;                        SPFieldUserValueCollection uu = new SPFieldUserValueCollection(web, item[dispName].ToString());                        foreach (SPFieldUserValue u in uu)                        {                            if (u.User != null)                            {                                if (UserID == u.User.ID)                                    value = true;                            }                            else                            {                                string userStr = u.ToString().Split(';')[0];                                int groupID = Convert.ToInt32(userStr);                                SPGroup group = web.SiteGroups.GetByID(groupID);                                foreach (SPUser user in group.Users)                                {                                    if (UserID == user.ID)                                        value = true;                                }                            }                        }                    }                }            }            catch { }            return value;        }

2. Getting Menu menus is a little tricky;

    public static string GetMenu(string ListName)        {            string menuHtml = string.Empty;            using (SPSite site = new SPSite(SITEURL))            {                using (SPWeb web = site.OpenWeb())                {                    SPList list = web.Lists.TryGetList(ListName);                    SPQuery query = new SPQuery();                    query.Query = "";                    SPListItemCollection itemcoll = list.GetItems(query);                    foreach (SPListItem item in itemcoll)                    {                        string Title = list.Fields.GetFieldByInternalName("Title").Title;                        string Link = list.Fields.GetFieldByInternalName("Link").Title;                        string IsShow = list.Fields.GetFieldByInternalName("IsShow").Title;                        string IsOpenNewPage = list.Fields.GetFieldByInternalName("IsShow").Title;                        menuHtml += item[Title].ToString();                    }                }            }            return menuHtml;        }
