XmlReader xmlFile;
xmlFile = XmlReader.Create(sb);
DataSet ds = new DataSet();
ds.ReadXml(xmlFile);
dataGridView1.DataSource = ds.Tables[0];

Answer 1

Just ToString() the StringBuilder :

XmlReader xmlFile;
xmlFile = XmlReader.Create(sb.ToString());
DataSet ds = new DataSet();
ds.ReadXml(xmlFile);

You might want to however checkout HttpClient as consuming a web service with XmlReader.Create feels just plain dirty
