我正在尝试获取我在搜索过滤器上声明的所有来自EWS的电子邮件，在控制台中显示所有记录，但当我尝试将其查看到具有gridview的网页时，它只显示第一个记录并显示超过20+的gridview。这是我的代码：
protected void Button1_Click(object sender, EventArgs e)
{
EmailMethods email = new EmailMethods();
email.EmailServer = "https://SampleEWSEmail.asmx";
email.AccountName = ConfigurationManager.AppSettings["Account"];
email.Password = ConfigurationManager.AppSettings["Secret"];
email.Domain = ConfigurationManager.AppSettings["Domain"];
email.GetEmails();
DataTable dt = new DataTable();
dt.Columns.Add("Subject", typeof(string));
dt.Columns.Add("Sender", typeof(string));
dt.Columns.Add("DateSent", typeof(string));
dt.Columns.Add("DateReceive", typeof(string));
foreach (string item in email.EmailList)
{
dt.Rows.Add(email.Subject, email.Sender, email.DateSent, email.DateReceive);
}
GridView1.DataSource = dt;
GridView1.DataBind();
}
}
public void GetEmails()
{
if (EmailServer != "" && AccountName != "" && Password != "")
{
try
{
EmailList = new List<string>();
ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain, sslPolicyErrors) => true;
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.Credentials = new WebCredentials(AccountName, Password, Domain);
service.Url = new Uri(EmailServer);
DisplayErrorEmails(service);
}
catch (Exception ex)
{
Status = "Error: " + ex.Message;
}
}
else
{
Status = "Please provide the Email Server, Account Name and Password.";
}
}
private bool DisplayErrorEmails(ExchangeService service)
