sharepoint 中獲取用的 控件

sharepoint封裝好的，直接那來用就行了 

<wssawc:PeopleEditor AllowEmpty="false" ValidatorEnabled="true" id="userPicker" runat="server"
                    ShowCreateButtonInActiveDirectoryAccountCreationMode="true" SelectionSet="User" />
後臺去值用

string[] user = userPicker.CommaSeparatedAccounts.Split(new string[] { "," }, StringSplitOptions.None);//獲取被提問人用戶
