使用Silverlight和WCF上传文件 [英] File Upload using Silverlight and WCF

问题描述

我正在尝试使用Silverlight和WCF读取文件（文件流）。我在WCF配置中使用了basicHttpBinding并创建了一个数据契约来捕获文件内容为byte []（字节数组）。

I am trying to read the file (file stream) using Silverlight and WCF. I have used basicHttpBinding in WCF configuration and created a data contract to capture the file contents as byte[] (byte array).

当我尝试发送文件内容（字节数组）时从Silverlight到WCF代理，我收到CommunicationException错误。

when I am trying to send the file content (byte array) from Silverlight to WCF proxy, I am getting CommunicationException error.

事实上，我按照以下博客中提到的相同步骤进行操作 - http://www.dotnetspark.com/kb/1510 -file-upload-from-silverlight-using-wcf-server.aspx

Infact, I follow the same steps as mentioned in the following blog - http://www.dotnetspark.com/kb/1510-file-upload-from-silverlight-using-wcf-server.aspx

任何帮助都将不胜感激。

Any help would be appreciated.

谢谢和问候，

推荐答案

多少bytes是文件？您可能有引用问题。

How many bytes is the file? You probably have a quote problem.

您的服务器上的web.config文件应该定义您的配额，否则配额非常小：

Your web.config file at the server should have your quotas defined, otherwise the quota is very small:

 <system.serviceModel>
  <bindings>
   <basicHttpBinding>
    <binding maxReceivedMessageSize="1048576" maxBufferSize="1048576" maxBufferPoolSize="1048576">
     <readerQuotas maxBytesPerRead="32768" maxStringContentLength="1048576" />
