Create an XML from a DataTable

Question

Using C# : I want to convert this table into XML. Please ignore

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.

DataTables are designed to iterate over rows, not columns like you have. There's nothing built-in to persist a DataTable in column-major order. You're going to have use custom code. Pseudo-code would be something like:

foeeach(DataColumn)
  if(name != "Name")
    output column header
    foreach(DataRow) 
      output row value

you can try using this

http://msdn.microsoft.com/en-us/library/system.data.datatable.writexml.aspx

DataTable youdatatable = GetData();
System.IO.StringWriter writer = new System.IO.StringWriter();
 youdatatable.WriteXml(writer, XmlWriteMode.WriteSchema, true);
 PrintOutput(writer);
