WCF 서비스를 사용하여 파일을 저장하는 방법

Question

데이터베이스 (C#)에 파일을 업로드 할 때 WCF를 사용하고 있는데이 오류가 발생했습니다. 원격 서버가 예기치 않은 응답 (413) 요청 엔터티를 너무 큼 반환했습니다. IService.cs에서

코드

[OperationContract] 
    void UploadFile(RemoteFileInfo request); 

[MessageContract] 공용 클래스 DownloadRequest { [MessageBodyMember] 공공 문자열 파일 이름; Service.svc.cs

public void UploadFile(RemoteFileInfo request) 
     { 
      AttachmentDTO objDTO = new AttachmentDTO(); 
      //FileStream targetStream = null; 
      Stream stream = request.FileByteStream; 
      const int bufferLen = 65000; 
      // byte[] buffer = new byte[bufferLen]; 
      // objDTO.FileData = buffer; 
      AttachmentBLL objBLL = new AttachmentBLL(); 
      try 
      { 
       byte[] readBuffer = new byte[bufferLen]; 

       int totalBytesRead = 0; 
       int bytesRead; 

       while ((bytesRead = stream.Read(readBuffer, totalBytesRead, readBuffer.Length - totalBytesRead)) > 0) 
       { 
        totalBytesRead += bytesRead; 

        if (totalBytesRead == readBuffer.Length) 
        { 
         int nextByte = stream.ReadByte(); 
         if (nextByte != -1) 
         { 
          byte[] temp = new byte[readBuffer.Length * 2]; 
          Buffer.BlockCopy(readBuffer, 0, temp, 0, readBuffer.Length); 
          Buffer.SetByte(temp, totalBytesRead, (byte)nextByte); 
          readBuffer = temp; 
          totalBytesRead++; 
         } 
        } 
       } 

       byte[] buffer = readBuffer; 
       if (readBuffer.Length != totalBytesRead) 
       { 
        buffer = new byte[totalBytesRead]; 
        Buffer.BlockCopy(readBuffer, 0, buffer, 0, totalBytesRead); 
       } 
       objDTO.FileData = buffer; 
       objDTO.FileName = request.FileName; 
       objDTO.CreatedDate = DateTime.Now; 
       objDTO.CreatedBy = "user"; 
       objDTO.IsActive = true; 
       objDTO.FileExt = request.FileExt; 
       objBLL.AddAttachment(objDTO); 


      } 
      catch (Exception ex) 
      { 

      } 

     } 

objBLL.AddAttachment (objDTO)에서 }

[MessageContract] 
public class RemoteFileInfo : IDisposable 
{ 
    [MessageHeader(MustUnderstand = true)] 
    public string FileName;  

    [MessageHeader(MustUnderstand = true)] 
    public int ItemID; 
    [MessageHeader(MustUnderstand = true)] 
    public string FileExt; 
    [MessageBodyMember(Order = 1)] 
    public System.IO.Stream FileByteStream; 

    public void Dispose() 
    { 
     if (FileByteStream != null) 
     { 
      FileByteStream.Close(); 
      FileByteStream = null; 
     } 
    } 

코드; 이 방법은 비즈니스 논리 파일에 있습니다. BLL은 DAL과 통신 할 수 있지만 DAL은 WCF 서비스와 통신 할 수 없습니다.

This Code is written in page.aspx.cs file. 



if (fuAttachment.HasFile) 
      { 
       string abs = fuAttachment.PostedFile.FileName; 
       System.IO.FileInfo fileInfo = new System.IO.FileInfo(fuAttachment.PostedFile.FileName); 

       MyService.RemoteFileInfo uploadRequestInfo = new MyService.RemoteFileInfo(); 

       using (System.IO.FileStream stream = new System.IO.FileStream(fuAttachment.PostedFile.FileName, System.IO.FileMode.Open, System.IO.FileAccess.Read)) 
       { 
        uploadRequestInfo.FileName = fuAttachment.FileName; 
        uploadRequestInfo.Length = fileInfo.Length; 
        uploadRequestInfo.FileByteStream = fuAttachment.FileContent; 
        uploadRequestInfo.ItemID = itemId; 
        uploadRequestInfo.FileExt = fuAttachment.PostedFile.ContentType; 
        client.UploadFile(uploadRequestInfo.FileExt, uploadRequestInfo.FileName, uploadRequestInfo.ItemID, uploadRequestInfo.FileByteStream); 

       } 
      }

문제가 해결되지 않을 경우이 같은 예를 들어, 데이터를 압축하고 webservice.There을 통해 전송하는 메커니즘을 따라 당신이 찾을 수있는 샘플을 많이하는 필요합니다.
