调用dbhelper类怎么写插入代码？

Question

初学三层架构，在DbHelper类中写了一个Command存储过程的方法
DbHelper  public static int ExecuteCommand(string spName, CommandType ct, params SqlParameter[] values)
        {
            SqlCommand cmd = new SqlCommand();
            cmd.Connection = Connection;
            cmd.CommandType = ct;
            cmd.CommandText = spName;
            cmd.Parameters.AddRange(values);
            int result = cmd.ExecuteNonQuery();
            return result;
        }//存储过程已经写好了
然后就数据访问层写插入代码，我写到一半不知道要怎么写？
DAL
  public static int insertAddress(string ReceiveName,string Address,string Post,string Mobile)
      {
          SqlParameter [] paras=new SqlParameter[4];
          paras[0]=new SqlParameter("@ReceiveName",SqlDbType.VarChar,20);
          paras[1]=new SqlParameter("@Address",SqlDbType.VarChar,20);
          paras[2]=new SqlParameter("@Post",SqlDbType.VarChar,20);
          paras[3]=new SqlParameter("@Mobile",SqlDbType.VarChar,20);
          paras[0].Value=ReceiveName;
          paras[1].Value=Address;
          paras[2].Value=Post;
          paras[3].Value=Mobile;
          using (SqlCommand cmd = DBHelper.ExecuteCommand("procInsertAdd", CommandType.StoredProcedure, paras))
          {
             //这里不知道要怎么写了？
          }
      }帮我看看要怎么写啊？

悲剧..你参考下吧

Answer 2

你给我的是 dbhelper类啊 ，我 看了有什么用，我的dbhelper已经写出来了，我要的是 在数据访问层里怎么写？还有 web层怎么判断插入成功？

Answer 3

 using (SqlCommand cmd = DBHelper.ExecuteCommand("procInsertAdd", CommandType.StoredProcedure, paras))
          {
             //这里不知道要怎么写了？
          }
//DBHelper.ExecuteCommand 返回的是int
//直接 return DBHelper.ExecuteCommand("***")web层，看你存储过程怎么写的了
一种是返回影响行数，判断是否大于0
一种是如果自增，返回最后生成的自增ID，大于0就OK了

Answer 4

 public static int AddGame(Game game)
{
            try
            {     
SqlParameter[] para = new SqlParameter[]
{
new SqlParameter("@gameName", game.GameName),
new SqlParameter("@gameUrl", game.GameUrl),
new SqlParameter("@gameDesc", game.GameDesc)
};                return DBHelper.ExecuteCommand("proc_InsertGame", para);
            }
            catch (Exception e)
            {
Console.WriteLine(e.Message);
                throw e;
            }
}DBHelper.ExecuteCommand执行后返回结果  如果是>0就是成功,<=0就是失败

Answer 5

我用的是存储过程,,你可以吧proc_InsertGame写成sql语句

Answer 6

int i= DBHelper.ExecuteCommand("procInsertAdd", CommandType.StoredProcedure, paras)
paras SqlParameter类型的数组
