有什么问题？请求服务器上的值是否未转换为INT

请帮忙

您的Delivery元素有许多子元素，这些子元素的类型不能以空字符串作为值传递。从XML中删除minOccurs属性值为0的元素，或者将其设置为可接受的值。例如，OrderType为Int类型，OrderValue为Decimal类型，RestOrder和ReturnOrder均为Boolean类型

请在此处查看XSD以获取类型信息：

答案是否有帮助？

The  formatter threw an exception while trying to deserialize the message: 
There was an error while trying to deserialize parameter
http://tempuri.org/:Delivery. 

The InnerException message was 'There was an error deserializing the 
object of type DreamLogisticsService.Delivery. 
The value '' cannot be parsed as the type 'Int32'.'.
