我想从我的c＃客户端调用一个wcf服务函数，该服务位于远程站点。所以需要通过动态链接服务来调用该函数。
在调用函数并传递所需参数时，它会抛出一个
的异常“类型'TMsgInParam'的对象无法转换 输入'omni.infrasofttech.com.TMsgInParam'“
所以我需要知道如何将复杂类型参数传递给该函数。
现在这里是我必须连接的服务的wsdl文件数据：

operationParameters[3] = MsgInParam;
// Get the metadata file from the service.

MessageBox.Show("Login reply received- " + retVal.ToString());
