SqlConnection conn = new SqlConnection("server=localhost;uid=sa;pwd=2;database=k");
            SqlCommand com = new SqlCommand("P_jinhuo ", conn);           
             = CommandType.StoredProcedure;
            com.Parameters.AddWithValue("@Usermc", textBox1.Text);
            com.Parameters.AddWithValue("@Userpz", textBox2.Text);
            com.Parameters.AddWithValue("@Usergg", textBox3.Text);
            这个com.Parameters.AddWithValue("@Usertm", textBox4.Text);
            这个com.Parameters.AddWithValue("@Userdj", textBox5.Text);
            com.Parameters.AddWithValue("@Usersl", textBox6.Text);
                 conn.Open();
            com.ExecuteNonQuery();
这个积要传给存储过程@Userdj = @UserdjtextBox4.Text 乘以 textBox5.Text 应该怎么写啊，不太明白

Convert.ToInt32(textBox4.Text)*Convert.ToInt32(textBox5.Text);

谢谢解决了
float a = Convert.ToInt32(textBox5.Text) * Convert.ToInt32(textBox6.Text);
com.Parameters.AddWithValue("@Userzj", a);
