wcf 서비스에서 대량의 데이터를 스트리밍해야합니다.

Question

서버 코드

public class SIIUnzipDecodeService : ISIIUnzipDecodeService 
{ 
    //Upload the large data file 

    public void UploadFile(RemoteFileInfo request) 
    { 
     FileStream targetStream = null; 
     Stream sourceStream = request.FileByteStream; 

     string uploadFolder = @"C:\upload\"; 
     string filePath = @"C:\upload\1GB.zip"; 
     //Path.Combine(uploadFolder, request.FileName); 

     using (targetStream = new FileStream(filePath, FileMode.Create, FileAccess.Write, FileShare.None)) 
     { 
      //read from the input stream in 6K chunks 
      //and save to output stream 
      const int bufferLen = 65000; 
      byte[] buffer = new byte[bufferLen]; 
      int count = 0; 

      while ((count = sourceStream.Read(buffer, 0, bufferLen)) > 0) 
      { 
       targetStream.Write(buffer, 0, count); 
      } 

      targetStream.Close(); 
      sourceStream.Close(); 
     } 

    } 

인터페이스 메모리 예외 system.outof 오류가 발생.

Answer 1

Tracing 서비스를 활성화 할 수 있습니까? 또한 서비스 구성을 게시하십시오. 당신이 당신의 서비스 구성에서 아래의 것들을 설정했는지 확인하십시오

<dataContractSerializer maxItemsInObjectGraph="2147483647"/> 

<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" 
      maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> 

<basicHttpBinding> 
     <binding transferMode="Buffered"/> 
</basicHttpBinding>
