if (b == 1)


this.type_of_login = "Normal_Login";

[login to view URL]["Login_Type"] = this.type_of_login;

[login to view URL]["Email_ID"] = [login to view URL]([login to view URL][0]["Email_ID"]);

[login to view URL]["Full_Name"] = [login to view URL]([login to view URL][0]["Full_Name"]);

It looks like above highlighted method is the cause of crash. Checking what the highlighted method is doing:

// [login to view URL]

public DataTable Check_User_Credential()


daUser daUser = new daUser();

[login to view URL](daUser);

return daUser.Check_User_Credential();


Dumping the highlighted method:

// [login to view URL]

public DataTable Check_User_Credential()


DataTable result;



DateTime t = [login to view URL]("2019-03-27", "yyyy-MM-dd", null);

if ([login to view URL] > t)


result = null;




SqlConnection sqlConnection = new SqlConnection();

SqlCommand sqlCommand = new SqlCommand();

SqlDataAdapter arg_AD_0 = new SqlDataAdapter();

DataTable dataTable = new DataTable();

string connectionString = [login to view URL]([login to view URL]["CRM"].ConnectionString);
