 < form id =form1runat =server> 
< div id =loginform> 
< div id =NotLoggedInrunat =server> 
使用< img src =http://www.google.com/favicon.ico/>登录
< asp：按钮ID =btnLoginToGoogleRunat =serverText =GoogleOnCommand =OpenLogin_Click
 CommandArgument =https://www.google.com/accounts/o8/ id/> 
< p />< asp：Label runat =serverID =lblAlertMsg/> 
< / div> 
< / div> 
< / form> 
 
使用System; 
使用System.Collections.Generic; 
使用System.Linq; 
使用System.Web; 
使用System.Web.UI; 
使用System.Web.UI.WebControls; 
使用DotNetOpenAuth.OpenId; 
使用DotNetOpenAuth.OpenId.RelyingParty; 
 
 public partial class _Default：System.Web.UI.Page 
 {
 protected void Page_Load（object sender，EventArgs e）
 {
 OpenIdAjaxRelyingParty rp = new OpenIdAjaxRelyingParty（）; 
 var r = rp.GetResponse（）; 
 if（r！= null）
 {
 switch（r.Status）
 {
 
 
 case AuthenticationStatus.Authenticated：
 NotLoggedIn.Visible = false; 
 Session [GoogleIdentifier] = r.ClaimedIdentifier.ToString（）; 
 Response.Redirect（Default2.aspx）; 
休息; 
 case AuthenticationStatus.Canceled：
 lblAlertMsg.Text =取消。; 
休息; 
 
 
 
 
保护无效OpenLogin_Click（object sender，CommandEventArgs e）
 {
 string discoveryUri = e .CommandArgument.ToString（）; 
 OpenIdRelyingParty openid = new OpenIdRelyingParty（）; 
 var b = new UriBuilder（Request.Url）{Query =}; 
 var req = openid.CreateRequest（discoveryUri，b.Uri，b.Uri）; 
 req.RedirectToProvider（）; 
} 
} 
  

但是我仍然有进一步的疑问是如何获得用户登录后创建会话的用户名... ???我可以看到它在某处...

        <div id="NotLoggedIn" runat="server">

            <asp:Button ID="btnLoginToGoogle" Runat="server" Text="Google"     OnCommand="OpenLogin_Click"  
              CommandArgument="https://www.google.com/accounts/o8/id" />  
          <p /><asp:Label runat="server" ID="lblAlertMsg" />  
        </div>  
      </div>  
    </form>

    protected void Page_Load(object sender, EventArgs e)
    {
        OpenIdAjaxRelyingParty rp = new OpenIdAjaxRelyingParty();
        var r = rp.GetResponse();
        if (r != null)
        {
            switch (r.Status)
            {


       case AuthenticationStatus.Authenticated:
                NotLoggedIn.Visible = false;
                Session["GoogleIdentifier"] = r.ClaimedIdentifier.ToString();
                Response.Redirect("Default2.aspx");
                break;
            case AuthenticationStatus.Canceled:
                lblAlertMsg.Text = "Cancelled.";
                break;
        }

    }

}
protected void OpenLogin_Click(object sender, CommandEventArgs e)
{
    string discoveryUri = e.CommandArgument.ToString();
    OpenIdRelyingParty openid = new OpenIdRelyingParty();
    var b = new UriBuilder(Request.Url) { Query = "" };
    var req = openid.CreateRequest(discoveryUri, b.Uri, b.Uri);
    req.RedirectToProvider();
