大家好我有这个代码:

SqlCommand scom = new SqlCommand(
                                "INSERT INTO klient(name,surname) 
                                values(@kname,@ksurname)", 
                                conn);

scom.Parameters.AddWithValue("@kname", kname.Text);
scom.Parameters.AddWithValue("@ksurname", ksurname.Text);
conn.Open();
DataTable dt = new DataTable();
SqlDataAdapter SDA = new SqlDataAdapter("SELECT * FROM klient", spojeni);
SDA.Fill(dt);
conn.Close();

它应该插入来自文本框的数据:kname,ksurname,但它关闭表单而不在MS SQL表中显示它们klient
