XML反序列化出错，XML 文档(2, 2)中有错误

XML转换为实体类的错误处理方案

一.错误描述：

• XML反序列化出错，XML 文档(2, 2)中有错误

二.解决方案：

• 在实体类的字段要加上XmlElement属性

三.具体实现:

1.XML文档

    <EVENT_INSTANCE><EventType>ALTER_TABLE</EventType><PostTime>2015-08-04T10:21:14.670</PostTime><SPID>175</SPID><ServerName>E6SER14</ServerName><LoginName>sa</LoginName><UserName>dbo</UserName><DatabaseName>E6ETms</DatabaseName><SchemaName>ETms</SchemaName><ObjectName>Driver</ObjectName><ObjectType>TABLE</ObjectType><AlterTableActionList><Drop><Constraints><Name>DF_Driver_DriverID</Name></Constraints></Drop></AlterTableActionList><TSQLCommand><SetOptions ANSI_NULLS="ON" ANSI_NULL_DEFAULT="ON" ANSI_PADDING="ON" QUOTED_IDENTIFIER="ON" ENCRYPTED="FALSE" /><CommandText>ALTER TABLE ETms.DriverDROP CONSTRAINT DF_Driver_DriverID</CommandText></TSQLCommand>
</EVENT_INSTANCE>

2.目标实体对象

[XmlRoot(ElementName = "EVENT_INSTANCE")]
[Serializable]
public class EventModel
{[XmlElement(ElementName = "EventType")]public string EventType { set; get; }[XmlElement(ElementName = "PostTime")]public string PostTime { set; get; }[XmlElement(ElementName = "SPID")]public string Spid { set; get; }[XmlElement(ElementName = "ServerName")]public string ServerName { set; get; }[XmlElement(ElementName = "UserName")]public string UserName { set; get; }[XmlElement(ElementName = "DatabaseName")]public string DatabaseName { set; get; }[XmlElement(ElementName = "SchemaName")]public string SchemaName { set; get; }[XmlElement(ElementName = "ObjectName")]public string ObjectName { set; get; }[XmlElement(ElementName = "ObjectType")]public string ObjectType { set; get; }[XmlElement(ElementName = "TargetObjectName")]public string TargetObjectName { set; get; }[XmlElement(ElementName = "TargetObjectType")]public string TargetObjectType { set; get; }[XmlElement(ElementName = "PropertyName")]public string PropertyName { set; get; }[XmlElement(ElementName = "PropertyValue")]public string PropertyValue { set; get; }[XmlElement(ElementName = "Parameters")]public Parameters Parameters { get; set; }[XmlElement(ElementName = "TSQLCommand")]public TsqlCommand TsqlCommand { get; set; }
}public class TsqlCommand
{
[XmlElement(ElementName = "CommandText")]
public string CommandText { set; get; }
[XmlElement(ElementName = "SetOptions")]
public string SetOptions { set; get; }
}
public class Parameters
{
[XmlElement("Param")]
public List<string> ParamContent { get; set; }
}

3.XML转实体类测试

//xmlStr 是xml字符串   ；type是要转换目标实体的类型 【typeof (EventModel)】；
public static object DeserializeFromXml(string xmlStr, Type type)
{try{using (StringReader sr = new StringReader(xmlStr)){XmlSerializer xs = new XmlSerializer(type);return xs.Deserialize(sr);}}catch (Exception ex){throw (ex);}
}
