排球积分程序

开发流程如下：

项目计划

   完成这个项目需要的时间：5-7天

项目开发

  需求分析：

   作为一名现场记分员，我希望详细记录比赛现场比分增长情况，以便观众及运动员、教练员及时掌握比赛状况。

  设计文档

    由排球比赛用户故事的需求分析可知，此程序是用来统计各个队伍的比分和积分情况，每一次比分的改变，都要形成一条记录。

  计划复审

 目前在进行中

  代码规范

    根据Visual Studio 2010规范去写。

  具体设计

   URL活动图如下：

代码如下：

namespace LessonDAL
{
public class SqlHelper
{
private static readonly string strcon = ConfigurationManager.ConnectionStrings["connectionStr"].ConnectionString;
public static int ExecuteNonQuery(string sql,params SqlParameter[] pms)
{
using (SqlConnection con = new SqlConnection(strcon))
{
using(SqlCommand cmd=new SqlCommand (sql,con))
{
if(pms!=null)
{
cmd.Parameters.AddRange(pms);
}
con.Open();
return cmd.ExecuteNonQuery();
}
}
}

public static object ExecuteScalar(string sql, params SqlParameter[] pms)
{
using (SqlConnection con = new SqlConnection(strcon))
{
using (SqlCommand cmd = new SqlCommand(sql, con))
{
if (pms != null)
{
cmd.Parameters.AddRange(pms);
}
con.Open();
return cmd.ExecuteScalar();
}
}
}

public static SqlDataReader ExecuteReader(string sql, params SqlParameter[] pms)
{
SqlConnection con = new SqlConnection(strcon);
using (SqlCommand cmd = new SqlCommand(sql, con))
{
if (pms != null)
{
cmd.Parameters.AddRange(pms);
}
con.Open();
return cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection); ;
}
}

public static DataTable ExecuteDataTable(string sql, params SqlParameter[] pms)
{
DataTable dt = new DataTable();
using(SqlDataAdapter adapter=new SqlDataAdapter (sql,strcon))
{
if(pms!=null)
{
adapter.SelectCommand.Parameters.AddRange(pms);
}
adapter.Fill(dt);
}
return dt;
}
