钉钉发送工作通知

下载官方.NET SDK，编译之后生成 TopSdk.dll，C#项目中引用这个DLL文件 ，也可以在项目中带着官方代码。

一、准备工作：

CorpId：认证的企业都有这个，敏感信息，拒绝泄露

CorpSecret：认证的企业都有这个，敏感信息，拒绝泄露

AgentID：新建的H5应用会给应用凭证 AppKey，AppSecret，AgentID 发送工作通知需要 AgentID，其他两个不用。

二、查看官方文档，例子是JAVA。改成.Net 即可。园子有人用asyncsend 接口也能发送成功。我们这里使用官方文档中的接口。

https://oapi.dingtalk.com/topapi/message/corpconversation/asyncsend_v2

官方JVAV代码改成.NET没有碰到问题，直接上代码吧。
