淘宝开发实例asp.net使用Top4Net.dll

aspx：

<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
获得淘宝授权：  <asp:LinkButton ID="LinkButton1" runat="server" PostBackUrl="LinkButtonhttp://open.taobao.com/isv/authorize.php?appkey=test">LinkButton</asp:LinkButton>
   <br />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /><div>
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
</div>
</form>

当然系统中必须引入dll:Newtonsoft.Json.dll;Top4Net.dll
