Java 代码:

    @AdaptBy(type = UploadAdaptor.class)
    @At({"/upload"})
    @Ok("json")
    @POST
    @ApiOperation(name = "文件上传", description = "文件上传")
    @ApiResponses(implementation = Result.class)
    public Result<?> uploadFile(@Param("file") TempFile file,
                                HttpServletRequest request,
                                HttpServletResponse response,
                                AdaptorErrorContext error) throws IOException {
        Dumps.HTTP.all(request);
        if (error != null && error.getAdaptorErr() != null) {
            return Result.error(
                    log.isDebugEnabled() ? error.getAdaptorErr().getMessage() : "文件服务异常"
            );
        }

        String filePath = sysConfigService.getString(SecurityUtil.getAppId(), "UpdateFilesPath");
        String fileName = file.getSubmittedFileName();

        try {
            storageServer.upload(file.getInputStream(), fileName, filePath);
        } catch (IOException e) {
            return Result.error(log.isDebugEnabled() ? e.getMessage() : "文件服务异常");
        }
        return Result.success("文件上传成功");
    }

C# 代码(使用 RestSharp):

        public ReturnResult UploadFile(string appId, string filePath)
        {
            try
            {
                var request = new RestRequest()
                {
                    Method = Method.Post,
                    Resource = $"{baseUri}/upload",
                };
                // 读取文件内容并添加到请求中
                var fileInfo = new FileInfo(filePath);
                using (var fileStream = fileInfo.OpenRead())
                {
                    byte[] buffer = new byte[fileStream.Length];
                    fileStream.Read(buffer, 0, buffer.Length);
                    // 将文件作为字节数组添加到请求中
                    request.AddFile("file", buffer, Path.GetFileName(filePath));
                }

                // 执行请求
                var response = _client.Execute(request);
                // 确保 HTTP 请求成功
                if (response.IsSuccessful)
                {
                    // 读取请求内容
                    string jsonResponse = response.Content;
                    var result = JsonConvert.DeserializeObject<ReturnResult>(jsonResponse);
                    if (result.code != 0)
                    {
                        throw new Exception(result.msg);
                    }
                    else
                    {
                        return result;
                    }
                }
                else
                {
                    throw new Exception($"上传失败,HTTP 状态码:{response.StatusCode}");
                }
            }
            catch (Exception ex)
            {
                throw new Exception($"文件上传出错:{ex.Message}", ex);
            }
        }

如果java代码没问题,那就和nutz没关系,c# 另外google吧
