使用 c# 向 SII 提交 EnvioDTE 问题

Question

我正在使用 C# 将 Envio DTE 提交给智利的 SII。

现在我得到一个 html 响应，并得到一个 this

“HA OCURRIDO UN ERROR EN EL UPLOAD DEL ARCHIVO DE DOCUMENTOS TRIBUTARIOS ELECTRONICOS。”

我认为参数未正确传递。参数名称在他们的文档中是正确的。此请求应模拟网络浏览器。

如果有人可以帮助我，我真的很感激。 代码：

Answer 1

应该是tcp/ip socket通信，加密数据，模拟浏览器。

Answer 2

改变

System.Text.Encoding.UTF8.GetBytes()
System.Text.Encoding.ASCII.GetBytes()

由

System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes()

应该可以的。
