Remoting 调用远程sington对象的方法抛出异常
程序有三个模块组成，
一个公共模块dll，定义远程对象，及一些参数类
一个客户端exe，调用服务器端的远程sington对象的方法，传递可序列话的参数
一个服务器exe，提供客户端访问的远程sington对象
问题：在客户端调用方法时，服务器抛出异常，异常信息调用堆栈显示，是服务器获取客户端传输的参数时超时，请高手分析什么问题。
测试环境1：客户端在win7系统的电脑A，服务器在xp系统的电脑B，出现以上描述问题
测试环境2：同样的程序，客户端运行在xp，服务器运行在win7时，结果正常。

[解决办法]
先作个test() 无参数的方法，调用 下试一试，看下是否通讯正常。
