SoapHttpClientProtocol 的invoke 函数

[im2web]

如何使用 在 invoke 之前 和invoke 之后

获取 发送的soap 的内容 和 获取的soap 的内容呢？

[zhongjiekangping]

之前做过 这方面的 ， 就是实现一个 同名的 partial 类 然后 重载 invoke 函数，在函数里面 实现消息的 序列化 和 反序列化

今天发现当我们的程序上传大容量数据的时候，出现了异常SoapException.错误及堆栈信息如下：

错误信息：
((System.Web.Services.Protocols.SoapException)(ex)) {"运行配置文件中指定的扩展时出现异常。 ---> 超过了最大请求长度。"}

stackTrace:
在 System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)
在 System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
在 VAS.Flows.Common.cn.ceopen.vasvisit.newVersion.LiuLiangWebService.UpdataDomainFlux(String MachineName, DataTable dt)
在 VAS.Flows.Common.Statics.UploadAllData()

在网上查询说是web services的默认长度为4M,有一种方法是修改web config.不过看到你这个方法感觉更好！现正在利用你这部分代码，希望能解决问题。
