Question

Getting an error while reading xml document using readxml

Some existing code for reference

XmlDocument doc1 = new XmlDocument();
        doc1.LoadXml("abc.xml");
DataSet ds = new DataSet();
DataTable dt = new DataTable();
ds.ReadXml(doc1);
dt = ds.Tables[0];
GridView1.DataSource = dt;
GridView1.DataBind();

It gives error that readxml does not have valid argument

Answer 1

Firstly, doc1.LoadXml("abc.xml") is going to fail; that should be .Load("abc.xml") instead (the string "abc.xml" is not xml – it is a path).

ReadXml has a lot of overloads, but none for taking an XmlDocument. Perhaps give it a node-reader instead. Or simpler, perhaps just give it the stream or string:

        using (var file = File.OpenRead("abc.xml")){
            ds.ReadXml(file);
        }

no XmlDocument needed…
