   asp.net 2.0中的SqlConnection多了一个StatisticsEnabled属性和ResetStatistics()、RetrieveStatistics()两个方法,用于获取SQLServer的连接统计数据。

<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>
<%@ page language="C#" %>
<script runat="server">
   void Page_Load(object sender, EventArgs e)
   {
     string connString = "Northwind的连接串";
     SqlConnection conn = new SqlConnection(connString);
     conn.StatisticsEnabled = true;
     conn.ResetStatistics();
     conn.Open();
     SqlCommand cmd = new SqlCommand("SELECT * FROM Orders", conn);
     SqlDataReader reader = cmd.ExecuteReader();
     reader.Close();
     conn.Close();

   Hashtable ht = (Hashtable)conn.RetrieveStatistics();
     foreach (string key in ht.Keys)
     {
       Label1.Text += "Key: " + key + " = " + ht[key] + "<BR />";
     }
   }
</script>
<html>
<head id="Head1" runat="server">
   <title>Untitled Page</title>
</head>
<body>
   <form id="Form1" runat="server" autocomplete="on">
     <asp:Label ID="Label1" Runat="server" Text=""></asp:Label>
   </form>
</body>
</html>

运行后的结果就是SQLServer连接统计数据结果:

Key: NetworkServerTime = 0
Key: BytesReceived = 156913
Key: UnPReparedExecs = 1
Key: SumResultSets = 1
Key: SelectCount = 1
Key: PreparedExecs = 0
Key: ConnectionTime = 30
Key: ExecutionTime = 30
Key: Prepares = 0
Key: Bufferssent = 1
Key: SelectRows = 830
Key: ServerRoundtrips = 1
Key: CursorOpens = 0
Key: Transactions = 0
Key: BytesSent = 48
Key: BuffersReceived = 20
Key: IduRows = 0
Key: IduCount = 0
