ASP.NET 2.0里轻松获取数据库连接统计数据
ASP.NET2.0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。
<%@ImportNamespace="System.Data"%>
<%@ImportNamespace="System.Data.SqlClient"%>
<%@pagelanguage="C#"%>
<scriptrunat="server">
voidPage_Load(objectsender,EventArgse)
{
stringconnString="Northwind的连接串";
SqlConnectionconn=newSqlConnection(connString);
conn.StatisticsEnabled=true;
conn.ResetStatistics();
conn.Open();
SqlCommandcmd=newSqlCommand("SELECT*FROMOrders",conn);
SqlDataReaderreader=cmd.ExecuteReader();
reader.Close();
conn.Close();
Hashtableht=(Hashtable)conn.RetrieveStatistics();
foreach(stringkeyinht.Keys)
{
Label1.Text+="Key:"+key+"="+ht[key]+"<BR/>";
}
}
</script>
<html>
<headrunat="server">
<title>UntitledPage</title>
</head>
<body>
<formrunat="server"autocomplete="on">
<asp:LabelID="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
