Question

我正在开发一个使用asp.net编写的简单Web服务的wp7应用程序

Web服务在桌面应用程序中运行良好（用c＃编写）（也在Web浏览器中测试过，工作正常）但在wp7中无效。

以下是我在wp7中用来调用webservice的代码

BookService.BooklocationSoapClient client = new BookService.BooklocationSoapClient();
client.BookListCompleted += new EventHandler<BookService.BookListCompletedEventArgs>(client_BookListCompleted);
client.BookListAsync(dId);

void client_BookListCompleted(object sender, BookService.BookListCompletedEventArgs e)
{
       Debug.WriteLine(e.Result);
}

以下是我得到的例外

A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll
A first chance exception of type 'System.Net.WebException' occurred in System.Windows.dll
A first chance exception of type 'System.Net.WebException' occurred in System.Windows.dll
A first chance exception of type 'System.ServiceModel.FaultException' occurred in System.ServiceModel.dll
A first chance exception of type 'System.ServiceModel.FaultException' occurred in System.ServiceModel.dll

另外，我收到以下消息

Server was unable to process request. ---> Length cannot be less than zero.
Parameter name: length
