dnn 模块 获取服务器端路径、获取用户ID、需要登陆才能访问的页面的处理

1.获取模块的服务器端路径<%=TemplateSourceDirectory%>

2. 在模块中获取用户的ID 
UserInfo user = UserController.GetCachedUser(PortalController.GetCurrentPortalSettings().PortalId,Context.User.Identity.Name)

3.需要登录才能访问的页面的处理。
前台ASPX：
<asp:Label runat="server" Visible="false" ID="tipLogin">该项服务需要登陆才能使用，请</asp:Label>
<asp:HyperLink runat="server" Visible="false" ID="hlLogin">登陆</asp:HyperLink>

后台C#：
if (!Request.IsAuthenticated){ string returnUrl = HttpContext.Current.Request.RawUrl; if (returnUrl.IndexOf("?returnurl=") != -1) { returnUrl = returnUrl.Substring(0, returnUrl.IndexOf("?returnurl=")); } returnUrl = HttpUtility.UrlEncode(returnUrl); if (PortalSettings.LoginTabId != -1 && Request.QueryString["override"] == null) { hlLogin.NavigateUrl = Globals.NavigateURL(PortalSettings.LoginTabId, "", "returnUrl=" + returnUrl); } else { if (PortalSettings.HomeTabId != -1) { hlLogin.NavigateUrl = Globals.NavigateURL(PortalSettings.HomeTabId, "", "returnUrl=" + returnUrl); } else { hlLogin.NavigateUrl = Globals.NavigateURL(PortalSettings.ActiveTab.TabID, "", "returnUrl=" + returnUrl); } } tipLogin.Visible = true; hlLogin.Visible = true; RadGrid1.Visible = false; return;}
