WCF大文件上传中的内存异常不足

Question

I am trying to upload large files(>10GB) using WCF. The Service Web.config is as below

<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding" maxBufferPoolSize="2147483647000000" maxReceivedMessageSize="2147483647000000" transferMode="Streamed">
      <readerQuotas maxDepth="200000000" maxStringContentLength="2147483647"
     maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
    </binding>
  </basicHttpBinding>
</bindings>

<client>
  <endpoint address="http://localhost:42890/Service1.svc"  behaviorConfiguration="endpointBehavior"
    binding="basicHttpBinding" 
    contract="UploadFileService.IService1" name="BasicHttpBinding"  />
</client>

And the client side web.config as below

   <bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding" closeTimeout="10:00:00" openTimeout="10:00:00"
      receiveTimeout="10:00:00" sendTimeout="10:00:00" maxBufferPoolSize="2147483647000000"
      maxReceivedMessageSize="2147483647000000" />
  </basicHttpBinding>
</bindings>

I got insufficient memory exception when I run the code, How can I solve it?

Answer 1

In your solution, target x64 instead of Any CPU. This will allow more memory allocation.

However, depending on your solution, you might be able to Stream the file to disk, not requiring to use so much memory.
