Question

我在用于调用Web服务的代理类中遇到实例验证错误。此代理类由XSD2Code自动生成。对我来说，错误与它指向的代码不匹配。

异常详细信息：

System.InvalidOperationException：实例验证错误： 'LessThanOrEqualTo'无效 ComparisonOperatorType的值。

来源错误：

Line 12866:    cswgetCapabilitiesResponse csw.cswgetCapabilities(cswgetCapabilitiesRequest request)
Line 12867:    {
Line 12868:        return base.Channel.cswgetCapabilities(request);
Line 12869:    }
Line 12870:

Answer 1

“LessThanOrEqualTo”是否有效？我想这条消息说它试图将“LessThanOrEqualTo”反序列化为ComparisonOperatorType元素（或属性）的值，但字符串“LessThanOrEqualTo”对元素的类型无效。
