我正在尝试在标签中显示SQL查询结果,但它没有显示.这是我的代码:

     string result = "SELECT ACTIVE FROM [dbo].[test] WHERE ID = '" + ID.Text + "' ";
     SqlCommand showresult = new SqlCommand(result, conn);
     conn.Open();
     showresult.ExecuteNonQuery();
     string actresult = ((string)showresult.ExecuteScalar());
     ResultLabel.Text = actresult;
     conn.Close();

需要帮助.谢谢!
