c# - Create an XML from a DataTable

Question

Using C# : I want to convert this table into XML. Please ignore the mistakes in row names. This is test data. I have given sample of two columns converted to xml and the corresponding rows as attributes . But i actually want for all columns. This is a Datatable.

Answer 1

public static string ToXml(this DataTable table, int metaIndex = 0)
{
    XDocument xdoc = new XDocument(
        new XElement(table.TableName,
            from column in table.Columns.Cast<DataColumn>()
            where column != table.Columns[metaIndex]
            select new XElement(column.ColumnName,
                from row in table.AsEnumerable()
                select new XElement(row.Field<string>(metaIndex), row[column])
                )
            )
        );

    return xdoc.ToString();
}

This worked great for me. Thanks stackoverflow.
