DataContract反序列化XML
本文关键字:XML 反序列化 DataContract | 更新日期: 2023-09-27 18:28:37
我有这个XML:
<ResultData xmlns="http://schemas.datacontract.org/2004/07/TsmApi.Logic.BusinesEntities"
xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<Information>Schedule added.</Information>
<Success>true</Success>
</ResultData>
有没有一种方法只得到这样的结果:
<ResultData>
<Information>Sched added.</Information>
<Success>true</Success>
</ResultData>
没有下面例子中的所有其他内容?因为当我尝试获取下面显示的结果字符串的对象时,它不起作用。
数据合约XML序列化
我尝试使用的代码是:
var serializer = new XmlSerializer(typeof(ResultData));
var rdr = new StringReader(xmlResultString);
var resultingMessage = (ResultData)serializer.Deserialize(rdr);
最后一行显示错误:
An unhandled exception of type 'System.InvalidOperationException' occurred in System.Xml.dll
Additional information: There is an error in XML document (1, 2).
<ResultData xmlns='http://schemas.datacontract.org/2004/07/TsmApi.Logic.BusinesEntities'> was not expected.
结果数据:
[DataContract]
public class ResultData
{
[DataMember]
public bool Success
{
get;
set;
}
[DataMember]
public string Information
{
get;
set;
}
}
由于xml中的DataContract序列化命名空间,您看到了异常。理想情况下,您希望使用DataContractSerializer对此进行反序列化。
如果要使用XmlSerializer,则必须清理命名空间声明。以下内容将清理所有命名空间,并允许您使用XmlSerializer。在foreach循环中,我们必须删除IsNamespaceDeclaration属性,然后将元素Name属性设置为LocalName。
string xmlResultString = @"<ResultData xmlns=""http://schemas.datacontract.org/2004/07/TsmApi.Logic.BusinesEntities""
xmlns:i=""http://www.w3.org/2001/XMLSchema-instance"">
<Information>Schedule added.</Information>
<Success>true</Success>
</ResultData>";
var doc = XDocument.Parse(xmlResultString);
foreach (var element in doc.Descendants())
{
element.Attributes().Where(a => a.IsNamespaceDeclaration).Remove();
element.Name = element.Name.LocalName;
}
xmlResultString = doc.ToString();
var rdr = new StringReader(xmlResultString);
var serializer = new XmlSerializer(typeof(ResultData));
var resultingMessage = (ResultData)serializer.Deserialize(rdr);
