c# – UploadFile：WCF测试客户端不支持此操作,因为它使用类型Cl

我正在使用一个简单的上传设置(从here开始)对它进行测试,如果我只是将WCF服务作为“dll”引用它可以正常工作但是如果我尝试在它作为WCF服务运行它会给我一个错误的“UploadFile” “声明它不受支持的方法.

方法名称上带有红色X的确切消息：WCF测试客户端不支持此操作因为它使用类型FileUploadMessage.

我首先在Visual Studio 2012中创建一个WCF服务应用程序,并在我的界面中具有以下内容(IUploadService.cs)：

[ServiceContract]
public interface IUploadService
{
    [OperationContract(IsOneWay = true)]
    void UploadFile(FileUploadMessage request);
}

[MessageContract]
public class FileUploadMessage
{
    [MessageBodyMember(Order = 1)]
    public Stream FileByteStream;
}

它实现如此(UploadService.svc.cs)：

public void UploadFile(FileUploadMessage request)
{
    Stream fileStream = null;
    Stream outputStream = null;

    try
    {
         fileStream = request.FileByteStream;

         string rootPath = ConfigurationManager.AppSettings["RootPath"].ToString();

         DirectoryInfo dirInfo = new DirectoryInfo(rootPath);
         if (!dirInfo.Exists)
         {
             dirInfo.Create();
         }

         // Create the file in the filesystem - change the extension if you wish,// or use a passed in value from metadata ideally

         string newFileName = Path.Combine(rootPath,Guid.NewGuid() + ".jpg");

         outputStream = new FileInfo(newFileName).OpenWrite();
         const int bufferSize = 1024;
         byte[] buffer = new byte[bufferSize];

         int bytesRead = fileStream.Read(buffer,bufferSize);

         while (bytesRead > 0)
         {
             outputStream.Write(buffer,bufferSize);
             bytesRead = fileStream.Read(buffer,bufferSize);
         }
     }
     catch (IOException ex)
     {
          throw new FaultException<IOException>(ex,new FaultReason(ex.Message));
     }
     finally
     {
         if (fileStream != null)
         {
             fileStream.Close();
         }
         if (outputStream != null)
         {
             outputStream.Close();
         }
     }
} // end UploadFile

从它的外观应该工作,但从我通过查看几个stackoverflow和其他论坛问题的理解,似乎WCF不支持流,即使我们可以有类型流的绑定.我对此感到困惑,以及我做错了什么.

谢谢您的帮助.
