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-l*v/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 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();
}
