问题描述
hi I am trying to make a log in page as well as sign up page in asp.net using 3 tier architecture by using sql server architecture. 
嗨，我正在尝试通过使用SQL Server体系结构使用3层体系结构在asp.net中创建登录页面以及注册页面。 I am able to fetch data from sql server data base which I have manually inserted during table creation in database and I am able to use it in my log in page. 我可以从在数据库表创建期间手动插入的sql server数据库中获取数据，并且可以在登录页面中使用它。
I have also created a sign up page but I am not able to get the values from sign up webform textbox to sqlserver database I am getting some error kindly help me with this. 我还创建了一个注册页面，但是我无法从将Webform文本框注册到sqlserver数据库中获取值。我遇到一些错误，请帮我解决这个问题。

Try this: 尝试这个：
SqlConnection con = new SqlConnection(conString);
con.Open();
string ins= "Insert into [LOGINDETAILS](USERID, PASSWORD) VALUES (@param1 , @param2)";
SqlCommand cmd = new SqlCommand(ins,con);
cmd.Parameters.Add("@param1", SqlDbType.Varchar, 50).value = TextBox1.Text;
cmd.Parameters.Add("@param2", SqlDbType.Varchar, 50).value = TextBox2.Text;
cmd.CommandType = CommandType.Text;
cmd.ExecuteNonQuery();
con.Close()
