查詢我試圖執行是;

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["userinfo.ConnectionString"].ConnectionString); 
conn.Open(); 
// string uname = usernametextbox.Text; 
// string fname = fnametextbox.Text; 
// string lname = lnametextbox.Text; 
// string email = emailtextbox.Text; 
// string ppassword = passwordtextbox.Text; 
// string ccountry = DropDownListcountry.SelectedItem.Text; 

string insertQuery = "INSERT INTO user (UserName, FirstName, LastName, Email, Password, Country) VALUES (@uname, @fname, @lname, @email, @password, @country)"; 

SqlCommand comm = new SqlCommand(insertQuery, conn); 
//int temp = Convert.ToInt32(comm.ExecuteScalar().ToString()); 
comm.Parameters.AddWithValue("@uname", usernametextbox.Text); 
comm.Parameters.AddWithValue("@fname", fnametextbox.Text); 
comm.Parameters.AddWithValue("@lname", lnametextbox.Text); 
comm.Parameters.AddWithValue("@email", emailtextbox.Text); 
comm.Parameters.AddWithValue("@country", DropDownListcountry.ToString()); 
comm.Parameters.AddWithValue("@password", passwordtextbox.Text); 

comm.ExecuteNonQuery(); 
// Response.Redirect("manager.aspx"); 

conn.Close();

是用戶的一個關鍵的字，如果這樣環繞[]

"INSERT INTO [user] (UserName, FirstName, LastName, Email, Password, Country) 
      VALUES (@uname, @fname, @lname, @email, @password, @country)"; 

，或者你可以使用這個風格以及

"INSERT INTO [dbo].[user] (UserName, FirstName, LastName, Email, Password, Country) 
    VALUES (@uname, @fname, @lname, @email, @password, @country)";
