You were shown how to use parameterized queries in a solution to your previous question on this same piece of code!

i changed them .

try
{
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
conn.Open();
string insertQuery = "insert into veri (UyeAdi, UyeSifre, UyeMail) values (@KU, @SI, @MA)";
SqlCommand com = new SqlCommand(insertQuery, conn);
com.Parameters.AddWithValue("@KU", txtKullan.Text);
com.Parameters.AddWithValue("@SI", txtSifre.Text);
com.Parameters.AddWithValue("@MA", txtMail.Text);

com.ExecuteNonQuery();
//uyari.Text = "Kayıt başarıyla tamamlandı.";
//Response.Redirect("default3.aspx");
uyari.Text = "Kayıt başarıyla tamamlandı";
conn.Close();

}
catch (Exception ex)
{

Response.Write("Error" + ex.ToString());
}

Response.Write("işlem tamamlandı");

}

Solution 1

It's "insert", not "Instert".

Also use parameterised queries, your code is open to SQL injection attacks.
