将文本文件从.Net http客户端上传到InputStream格式的Java REST API

Question

我有一个案例，我想从.Net http客户端上传文本文件到InputStream格式的Java REST API。当我使用Form-Data Body中的File从Postman访问Java REST时，该文件在Java REST服务中得到了很好的接收。当我尝试从.Net客户端做同样的事情时，我得到了一些例外，如下所示。

我的.Net HTTP客户端代码如下，

var client = new HttpClient();
client.BaseAddress = new Uri("http://localhost:8082/processes/view/createDocumentfromFile/851");
client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Add("procId", "100");
client.DefaultRequestHeaders.Add("DocName", "ProphetWorkflow");
var content = new MultipartFormDataContent();
content.Add(new ByteArrayContent(File.ReadAllBytes(@"C:\Users\charan.ghate\Desktop\Calculation.txt")));
HttpResponseMessage messge = client.PostAsync(client.BaseAddress, content).Result;
if (messge.IsSuccessStatusCode)

    string result = messge.Content.ReadAsStringAsync().Result;
    lblResponse.Text = result;

我的Java REST服务代码如下，

@POST
@Path("/createDocumentfromFile/procId")
@Consumes( MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML, MediaType.TEXT_PLAIN )
@Produces( MediaType.APPLICATION_JSON )
public Response createDocumentfromFile(@PathParam("procId") Long piOID, @HeaderParam("DocName") String modulename,
        @Context HttpServletRequest request, @Context HttpServletResponse response,
        @FormDataParam("file") InputStream uploadedInputStream) 
//
//Operation on the input stream
//

当我点击REST API时，我在.Net以及Java中都得到了例外，详见下文

.Net错误消息：

StatusCode: 500, ReasonPhrase: 'Internal Server Error', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:

  Connection: close
  Date: Fri, 23 Dec 2016 15:08:03 GMT
  Server: Apache-Coyote/1.

能否请您建议将文件从.Net客户端传输到Java REST服务的最佳方法。
