將表單驗證添加到ADFS登錄

Question

我需要檢查傳遞給我的adfs登錄頁面的表單變量，但是當我向內置的Page_Load函數添加任何內容時，它會中斷。

FormsSignIn.aspx

<%@ Page Language="C#" MasterPageFile="~/MasterPages/MasterPage.master" AutoEventWireup="true"  ValidateRequest="false"
    CodeFile="FormsSignIn.aspx.cs" Inherits="FormsSignIn" Title="<%$ Resources:CommonResources, FormsSignInPageTitle%>"

            </td>
            <td>&nbsp;</td>
        </tr>
    </table>
</asp:Content>

public partial class FormsSignIn : FormsLoginPage

        } else {

            } */

    protected void HandleError( string message )
    {
        ErrorTextLabel.Visible = true;
        ErrorTextLabel.Text = Resources.CommonResources.IncorrectUsernameText;
    }

    {
        try
        {
            SignIn( UsernameTextBox.Text, PasswordTextBox.Text );

            HandleError( ex.Message );
        }
    }

您沒有提到如何添加代碼或代碼如何中斷，但是總的來說，直接修改文件時發現了問題。

鑒於ADFS只是另一個IIS應用程序，我對采用這種方法感到更加高興：
