Question

我正在尝试使用RestRequest.AddFileBytes将图像文件发布到服务中，但是当我这样做时，文件似乎已损坏。当我将其下载回去时，文件大小过小，并且取决于文件类型，它的扩展名可能似乎错误或无法解释（可能是b / c标头被弄乱了）

当我尝试对Postman做同样的事情时，文件就可以了，所以似乎与我发布文件的方式有所不同。请指教！

您不知道吗，就像发条一样，我在2天的大部分时间里都敲了一下脑袋，然后发布了这个问题，几乎立即想出了如何使它起作用。我不会留下我知道为什么一个人是正确的，而一个人只是主要是的权利（这显然不够好），但是

我只需要更改

request.AddFileBytes(fileName, bytes, fileName, contentType);

到

request.AddParameter(contentType, bytes, ParameterType.RequestBody);

RestRequest.AddFileBytes发布损坏的文件
