Gridview平均值问题
GridView里有一列数据如下

123.23
26.35
58.42
0.00
23.00
0.00
现在要求平均值,也就是把(123.23+26.35+58.42+23.00)/4,而零不做计算.请各位写出具体代码,别讲思路!!谢谢

e.Row.Cells[15].Text = ((double)(sum5 / GridView1.Rows.Count)).ToString("f");
e.Row.Cells[15].ForeColor = System.Drawing.Color.Red;

e.Row.Cells[16].Text = ((double)(sum6 / GridView1.Rows.Count)).ToString("f");
e.Row.Cells[16].ForeColor = System.Drawing.Color.Red;

上面的代码把0也算进去了.该怎么改?

HTML code
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
    DataKeyNames="ProductID" DataSourceID="SqlDataSource1" 
    onprerender="GridView1_PreRender" ShowFooter="True">
    <Columns>
        <asp:BoundField DataField="ProductID" HeaderText="ProductID" 
            InsertVisible="False" ReadOnly="True" />
        <asp:BoundField DataField="ProductName" HeaderText="ProductName"  />
        <asp:BoundField DataField="UnitPrice" HeaderText="UnitPrice" />
    </Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="Data Source=.;Initial Catalog=Northwind;Integrated Security=True" 
    ProviderName="System.Data.SqlClient" SelectCommand="select * from products">
</asp:SqlDataSource>
