寻求帮助

<form action="/foo" method="post">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                        <h4 class="modal-title">Login</h4>
                    </div>

                    <div class="modal-body">
                        <img src="xxx" style="height: 220px;background: white;padding: 60px;">
                        <div class="form-group">
                            <label for="exampleInputEmail1">Email address</label>
                            <input type="email" class="form-control" id="dic_username" name="email" aria-describedby="emailHelp"/>
                            <small id="emailHelp" class="form-text text-muted">We'll never share your email with anyone else.</small>
                        </div>
                        <div class="form-group">
                            <label for="exampleInputPassword1">Password</label>
                            <input name="password"  type="password" class="form-control" id="dic_password"/>
                        </div>
                      </div>

                    <div class="modal-footer">
                        <input class="btn btn-primary" value="Login" type="Submit" />
                        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                    </div>
                </form>

第foo.aspx.cs页

  try
                {
                    dynamic results = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(UnicodeEncoding.UTF8.GetString(client.UploadValues(url,"POST",client.QueryString)));
 Response.Redirect("/some route ");
}
catch (Exception ex)
                {
                    Response.Redirect("");

                }
                   

我希望在表单上显示错误,而不是重定向,我该怎么做,任何帮助将不胜感激
