in one project, I use datamember to serialize a class to an xml file, like,

```
[DataMember]
public string Member1;

```

later I query the xml to get one value out, like:

```
XmlNode1.SelectSingleNode("Member1");

```

Is it possible that make the `Member1` above to a variable so when I change the `DataMember` name to be `Member2` the `Member1` in the query can be changed to `Member2` automatically ,rather than I manually change it?
