System.Drawing.Image图像 批量生成并显示在web页面上

结合gridview显示出来。代码如下：

aspx文件中：

<asp:GridView ID="GridView1" runat="server" OnDataBound="GridView1_DataBound" OnRowDataBound="GridView1_RowDataBound"

AutoGenerateColumns="False" Width="100px">

<RowStyle BackColor="White" HorizontalAlign="Center" BorderWidth="0px" BorderColor="White"/>

<PagerStyle HorizontalAlign="Center" BorderWidth="0px" BorderColor="White" />

<SelectedRowStyle BackColor="White" Font-Bold="True" ForeColor="White" />

<HeaderStyle HorizontalAlign="Center" BorderWidth="0px" BorderColor="White"/>

<AlternatingRowStyle BackColor="White" BorderWidth="0px" BorderColor="White" />

<FooterStyle BorderWidth="0px" BorderColor="White" HorizontalAlign="Center" />

<Columns>

<asp:TemplateField HeaderText="請直接打印(ctrl+P)">

<ItemTemplate>

<asp:Label ID="Label1" runat="server" Text='<%# Bind("JiZhong") %>'></asp:Label>-

<asp:Label ID="Label2" runat="server" Text='<%# Bind("MoNO") %>'></asp:Label>-

<asp:Label ID="Label3" runat="server" Text='<%# Bind("JianNO") %>'></asp:Label>

<br/>

<asp:Image ID="barcodeimg" runat="server" ToolTip='<%# Bind("ID") %>'/>

</ItemTemplate>

</asp:TemplateField>

</Columns>

<EmptyDataTemplate>

</EmptyDataTemplate>

</asp:GridView>

cs文件中：

protected void GridView1_DataBound(object sender, EventArgs e)

{

for (int i = 0; i < GridView1.Rows.Count; i++)

{

System.Web.UI.WebControls.Image barcodeimg = (System.Web.UI.WebControls.Image)GridView1.Rows[i].Cells[0].FindControl("barcodeimg");

barcodeimg.ImageUrl = "~/code128.aspx?num=" + barcodeimg.ToolTip.ToString();

}

}
