使用RestSharp将文件上载到WCF

Question

I have searched for this but did not find the answer. I need to upload a file ( image or PDF) to a WCF REST service using RestSharp. I have used AddFile() method, but the service is not hit ( I added a break-point on the very first line of the method), and the returned response is an empty string.

I tried both byte[] and Stream. The web services is :

[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json,
    ResponseFormat = WebMessageFormat.Json)]
void NotesAttachment(Stream input);

Please I need example for both the service and how to call it from the client.

Using C# 4.5.1 on VS 2015.

Answer 1

Please refer to my example
IServcie1.cs

[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
Task UploadStream(Stream stream);

Service1.svc.cs

public async Task UploadStream(Stream stream)
        {
            using (stream)
            {
                using (var file = File.Create(Path.Combine(HostingEnvironment.MapPath("~/Uploads"), Guid.NewGuid().ToString() + ".png")))
                {
                    await stream.CopyToAsync(file);
                }
            }
        }

Client call example. Take the Postman as an example.
