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:
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.Driver
DROP 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);
}
}
