Introduction:
In this article,i am going to explain about how to reading and writing a XML using dataset.

Main:

For Reading XML using dataset,

DataSet ds = new DataSet(); ds.ReadXml("c:\\Sample.xml"); //Reading XML data, GridView1.DataSource = ds.Tables[0]; GridView1.DataBind();

For Writing XML using dataset,

string connectionString="user id=sa;Password=sa;database=localhost"; string commandString = "SELECT * FROM EMP"; OracleDataAdapter da = new OracleDataAdapter(commandString, connectionString); DataSet ds = new DataSet(); da.Fill(ds); ds.WriteXml("c:\\EMP.xml"); //writing dataset into xml file

Conclusion:
Hope this helps,
Happy Coding.
