两个自己平时写的方法，记录下来，方便以后查找使用；

1、判断用户是否在字段人员和组里面；

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(';')[];
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、获取Menu菜单，有点弱爆的赶脚；

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;
}
