我在WCF服务中定义了一个方法，它接受byte[]作为参数。当我调用函数时，它 An exception of type 'System.OutOfMemoryException' occurred in System.ServiceModel.ni.dll but was not handled in user code在Reference.cs中给出了一个错误。

这是我的代码

svc.GetDataUsingDataContractCompleted += new EventHandler<GetDataUsingDataContractCompletedEventArgs>(svc_GetDataUsingDataContractCompleted);
svc.GetDataUsingDataContractAsync(contents, "AllImagesZip.zip");

其中内容是 byte[] 的对象。我有以下Web.config文件。

<?xml version="1.0"?>

   <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>

  <security mode="None">
    <transport clientCredentialType="None" proxyCredentialType="None"
      realm="" />        
  </security>
</binding>    
  </basicHttpBinding>    
</bindings>

我已在IIS本地托管此服务。 内容对象包含17346288字节。我认为这个问题是由于互联网连接而出现的，但我的互联网连接工作正常。我得到了应该是什么错误？

我有一个类似的问题。如果我记得，你必须在你的 WCF 服务中修改 app.xaml 文件并提供更多的 maxbytes、maxpool ......类似的东西

我误以为我更新了 Web.Config 文件并最大化了以下内容：

maxBufferSize、maxBufferPoolSize 等。

您的数据传输模式设置为缓冲区，它试图缓冲内存中的全部内容。检查这篇文章 - WCF HttpTransport：流式传输与缓冲传输模式
