Question

How to get DataType specific DataTable from XML

This is my code

string XMLReportFormat =@"<?xml version="1.0" encoding="utf-8" ?>
<Table>
    <ReportBody>
      <TableRow>
        <ID>1</ID>
        <ParentID>1</ParentID>
        <Key>First1</Key>
      </TableRow>
      <TableRow>
        <ID>4</ID>
        <ParentID>1</ParentID>
        <Key>FirstChild4</Key>
      </TableRow>
    </ReportBody>
</Table>";

StringReader sReader = new StringReader(XMLReportFormat);
DataSet ds = new DataSet();

if (sReader == null)
    return null;
ds.ReadXml(sReader);

Here I am getting all DataType of columns as String.
I want some columns like ID and ParentID as Integer

Yeah ! I found the answer.

private static DataTable CreateDataTable()
{
    DataTable dt = new DataTable("TableRow");
    dt.Columns.Add(new DataColumn("ID", typeof(int)));
    dt.Columns.Add(new DataColumn("ParentID", typeof(int)));
    return dt;
}
public static DataTable GetReportFormatFromXML(string XMLReportFormat)
{
    if (XMLReportFormat == string.Empty)
        return null;
    StringReader sReader = new StringReader(XMLReportFormat);
    DataSet ds = new DataSet();

    if (sReader == null)
        return null;
    ds.Tables.Add(CreateDataTable());
    return ds.Tables[0];
}

This line helps me 🙂

ds.Tables.Add(CreateDataTable());
