ADO.Net:向程序传递查询字符串

页面query.aspx可以根据传递的id参数在数据库中进行查询，如：
http://gqa-eric-lv/aspnet/MyBBSQuery/query.aspx?id=26
程序中可以使用this.Request.QueryString["ID"]获取查询字符串ID的值，如下例：

   SqlConnection coreDB=new SqlConnection();
   coreDB.ConnectionString= "workstation id=\"GQA-ERIC-LV\";packet size=4096;integrated security=SSPI;" +
    "data source=\"gqa-eric-lv\";persist security info=False;initial catalog=CoreDB";
   
   int QueryID=3;
   string idStr=TextBox2.Text.Trim();
   QueryID=Convert.ToInt32(this.Request.QueryString["ID"]);
   if(QueryID<0||TextBox2.Text.Trim()!="")return;
   string mySelectQuery = "SELECT ID,Title,Content FROM myBBS where id="+QueryID;

   SqlCommand myCommand = new SqlCommand(mySelectQuery,coreDB);

   coreDB.Open();
   SqlDataReader myReader = myCommand.ExecuteReader();
   try
   {
    while (myReader.Read())
    {
     TextBox1.Text=myReader["title"].ToString();
     TextBox2.Text=myReader["ID"].ToString();
     TextBox3.Text=myReader["content"].ToString();     
    }   
   }
   finally
   {
    myReader.Close();
    coreDB.Close();
   }
