循环读取数据的疑问
SqlDataAdapter   sdr=new   SqlDataAdapter();
sdr.SelectCommand=new   SqlCommand( "select   top   10   *   from   UserPhoto   order   by   pid   desc ",conn);
DataSet   ds=   new   DataSet();
sdr.Fill(ds, "emp ");
for(int   i=0;i <=ds.Tables[0].Rows.Count;i++)
{
a   =   "sPicArr[ "+i+ "]   =   new   Array( 'UserPhoto/ "+ds.Tables[ "emp "].Rows[0][ "PhotoImg "].ToString()+ " '); ";
}
Response.Write(a);

我想读出前十条记录
现在数据库中只有四条记录

循环读出来的结果却是第一条，一共四条一样的
a   =   "sPicArr[ "+i+ "]   =   new   Array( 'UserPhoto/ "+ds.Tables[ "emp "].Rows[i][ "PhotoImg "].ToString()+ " '); ";

可是这样读的话，就会出错！
提示：在位置   4   处没有任何行

也是就是我改的那部分出错

请各位大哥帮帮忙

------解决方案--------------------
for(int i=0;i <ds.Tables[0].Rows.Count;i++)
{
a = "sPicArr[ "+i+ "] = new Array( 'UserPhoto/ "+ds.Tables[ "emp "].Rows[i][ "PhotoImg "].ToString()+ " '); ";
}
