Question

I’d like to use tabs, or at least more than 2 spaces per indent level. IIRC there are options available to adjust this when using serialization to write a class out; but I don’t see any way to adjust the behavior when calling MyDataSet.WriteXml(filename).

Answer 1

You need to use a XmlTextWriter if you want to influence the layout of your XML being saved:

XmlTextWriter xtw = new XmlTextWriter(filename, Encoding.UTF8);
xtw.Formatting = Formatting.Indented;
xtw.Indentation = 4;
xtw.IndentChar = '\t';

and then write out your data set using that XmlTextWriter:

MyDataSet.WriteXml(xtw);
