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
