我如何将XmlReader从Web服务传递到Silverlight [英] how i can pass XmlReader from web service to silverlight
问题描述
大家好
我在Web服务中创建了此方法
[WebMethod]
公开XmlReader fromxml()
{
XmlReader x;
cmd.Connection = conn;
cmd.CommandText =从test_emp中删除*";
conn.Open();
x = cmd.ExecuteXmlReader();
conn.Close();
x.Read();
返回x;
}
并在Silverlight中
s.fromxmlCompleted + = new EventHandler< fromxmlCompletedEventArgs>(s_fromxmlCompleted);
s.fromxmlAsync();
}
void s_fromxmlCompleted(对象发送者，fromxmlCompletedEventArgs e)
{
如果(e.Result！= null)
{
SilverlightApplication34.ServiceReference1.XmlReader x;
}
}
我想将其从Web服务获取到我的Silverlight应用程序
尝试给我错误时
远程服务器返回错误:NotFound.
和x没有其他方法，这个方法
x.PropertyChanged
感谢您的帮助

推荐答案
建议对:
1.确保可以从出现问题的计算机上访问clientaccesspolicy.xml和crossdomain.xml.
2.默认情况下，WCF服务添加wsHttpBinding.将其更改为basicHttpBinding.
突出显示的错误可能会消失.
Couple of suggestions:
1. Make sure that you can access clientaccesspolicy.xml & crossdomain.xml from the machine which is giving problem.
2. By default, WCF service adds wsHttpBinding. Change it to basicHttpBinding.
The highlighted error may go off.
当您修复NotFound错误时...
您不传递XmlReader对象.您将传递Xml数据并使用Silverlight的XmlReader类来解析它....
And when you fix the NotFound error...
You don''t pass XmlReader objects. You''d pass Xml data and use Silverlight''s XmlReader class to parse it....
