System.Xml.Serialization.XmlSerializer.Deserialize

Question

在System.Xml.Serialization.XmlSerializer.Deserialize中获取错误--这个XML文件接收表单为Salesfroce，异常发生在binding.Query()方法中。

string xml = @"<?xml version='1.0' encoding='UTF-8'?>
                <soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/' 
                        xmlns='urn:enterprise.soap.sforce.com' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' 
                        xmlns:sf='urn:sobject.enterprise.soap.sforce.com'>
                        <soapenv:Body>
                            <queryResponse>
                                <result>
                                    <done>true</done>
                                    <queryLocator xsi:nil='true'/>
                                    <records xsi:type='sf:Contact_Transaction__c'>
                                        <sf:Id xsi:nil='true'/>
                                        <sf:Is_in_SLA__c>Yes</sf:Is_in_SLA__c>
                                    </records>
                                    <records xsi:type='sf:Contact_Transaction__c'>
                                        <sf:Id xsi:nil='true'/>
                                        <sf:Is_in_SLA__c>Yes</sf:Is_in_SLA__c>
                                    </records>
                                </result>
                            </queryResponse>
                        </soapenv:Body>
                    </soapenv:Envelope>";

上层XML文档是soap responcemessage，它在获取自定义对象数据时从salesforce接收。此XML消息是有效的XML消息。如果我尝试手动使用沙化方法反序列化一个对象，那么也会得到XML内部文档错误。

看看您的模型对象"queryResponse"，它会使类型为Double的字段无法设置，因为接收到的值没有有效的格式。可能是该值为null (nil='true')，且该字段不可为空。
