XML怎么反序列化操作

C# code

dt.TableName = "ProText";dt.WriteXml(Application.StartupPath +@"\1.xml");//序列化成功下面反序列化不成功，是不是思路错了?private string filePath =Application.StartupPath +@"\1.xml";        StringReader strReader = new StringReader(filePath);XmlReader xmlReader = XmlReader.Create(strReader);XmlSerializer serializer = new XmlSerializer(typeof(DataTable));DataTable dt = serializer.Deserialize(xmlReader) as DataTable;dgvColumn.DataSource = dt;//数据为空。

[解决办法]
直接用ReadXml这个可以了。LZ那样写会很麻烦的dataset有字段的XML的
