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 runat="server">
＜title>Untitled Page＜/title>
＜/head>
＜body>
＜form runat="server" autocomplete="on">
＜asp:Label 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
