Schreiben eines REST-Service zum Hochladen einer Datei in C#

Question

Ich habe einen REST-Service geschrieben, um eine Datei hochzuladen. Scheint, als gäbe es ein Problem. Jedes Mal, wenn ich versuche, um die Datei zu laden mit einer Testkonsolenanwendung es mir einen Fehler gibt unten erwähnt:

An unhandled exception of type 'System.Net.WebException' occurred in System.dll

Additional information: The remote server returned an error: (400) Bad Request.

-Code - IFileUploaderService

[OperationContract] 
    [WebInvoke(Method = "POST", 
     UriTemplate = "/UploadImage", 
    RequestFormat = WebMessageFormat.Json, 
    ResponseFormat = WebMessageFormat.Json)] 
    void FileUpload(Stream stream); 

-Code - FileUploaderService.svc.cs

public void FileUpload(Stream stream) 
    { 
     string FilePath = Path.Combine(HostingEnvironment.MapPath("~/FileServer/Uploads"), "1.txt"); 

     int length = 0; 
     using (FileStream writer = new FileStream(FilePath, FileMode.Create)) 
     { 
      int readCount; 
      var buffer = new byte[8192]; 
      while ((readCount = stream.Read(buffer, 0, buffer.Length)) != 0) 
      { 
       writer.Write(buffer, 0, readCount); 
       length += readCount; 
      } 
     } 
    }

Konsole-Anwendung die Datei hochladen:

static void Main(string[] args) 
    { 

     System.Uri url = new System.Uri("http://localhost:8082/FileUploaderService.svc/uploadimage"); 
     string filePath = @"C:\test.jpg"; 



     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
     request.Accept = "application/octet-stream"; 
     request.Method = "POST"; 
     request.ContentType = "image/jpeg"; 
     using (Stream fileStream = File.OpenRead(filePath)) 
     using (Stream requestStream = request.GetRequestStream()) 
     { 
      int bufferSize = 1024; 
      byte[] buffer = new byte[bufferSize]; 
      int byteCount = 0; 
      while ((byteCount = fileStream.Read(buffer, 0, bufferSize)) > 0) 
      { 
       requestStream.Write(buffer, 0, byteCount); 
      } 
     } 
     string result; 
     using (WebResponse response = request.GetResponse()) 
     using (StreamReader reader = new StreamReader(response.GetResponseStream())) 
     { 
      result = reader.ReadToEnd(); 
     } 
     Console.WriteLine(result); 
    } 

ich gesehen habe, die genannten Lösungen in anderen Orten, aber es funktioniert nicht. Kann mir jemand dabei helfen, da ich mich frage, was mache ich falsch?

Answer 1

Anzahl:

requestStream.Close(); 

vor dieser Zeile:

string result; 

Dies wird der Strom führen zu spülen.
