流程如下
任务：作为一个排球计分员，我需要知道每场比赛队伍的得分和积分情况，以便对队伍进行排名和反馈。
计划：此程序需要2-3周
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。
具体代码如下
namespace dal
{
public static class SqlHelper
{
private static readonly string constr =
ConfigurationManager.ConnectionStrings["MyPC"].ConnectionString;
ExecuteNonQuery()
ExecuteScalar()
ExecuteReader()
ExecuteDataTable()
public static int ExecuteNonQuery(string sql, params SqlParameter[] pm
using (SqlConnection con = new SqlConnection(constr))
{
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(constr))
{
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(constr);
using (SqlCommand cmd = new SqlCommand(sql, con))
{
if (pms != null)
{
cmd.Parameters.AddRange(pms);
}
try
{
con.Open();
return cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection);
}
catch (Exception)
{
con.Close();
con.Dispose();
throw;
}
}
}
public static DataTable ExecuteDataTable(string sql, params SqlParameter[] pms)
{
DataTable dt = new DataTable();
using (SqlDataAdapter adapter = new SqlDataAdapter(sql, constr))
{
if (pms != null)
{
adapter.SelectCommand.Parameters.AddRange(pms);
}
adapter.Fill(dt);
}
return dt;
}
}
