Hi All,
Iam saving data in xml file using datatable.Iam getting values perfectly in that xml file.But whenever i save <,> symbols in that time i'm getting < > like that.How to solve this error.

This is My code:

DataTable mydt = new DataTable("MyDataTable");
DataSet newds = new DataSet("MyDataSet");
mydt.Columns.Add("ColumnName", System.Type.GetType("System.String"));
mydt.Columns.Add("Operator", System.Type.GetType("System.String"));
mydt.Columns.Add("Value", System.Type.GetType("System.String"));
mydt.Columns.Add("Conditions", System.Type.GetType("System.String"));
newds.Tables.Add(mydt);
for (count = 0; count < gridcol.Rows.Count; count++)
{
DataRow dr = mydt.NewRow();
dr[0] = gridcol.Rows[count].Cells[0].Text;
dr[1] = gridcol.Rows[count].Cells[1].Text;
dr[2] = gridcol.Rows[count].Cells[2].Text;
dr[3] = gridcol.Rows[count].Cells[3].Text;
mydt.Rows.Add(dr);
}
newds.AcceptChanges();
newds.Tables[0].WriteXml("D:\\Unicampus\\XMLFiles\\" + queryname + ".xml");
anybody can reply please
