the code look like this:


string strPersonSchema = "PersonPet.xsd";

XmlDataDocument datadoc = new XmlDataDocument();
datadoc.Dataset.DataSetName = "PersonPet";

// Create tables for people and pets
DataTable people = new DataTable( "Person" );

// Set up the columns in the Tables
DataColumn personname = new DataColumn( "Name", typeof(String) );
DataColumn personAge = new DataColumn( "Age", typeof(Int32) );

// Add columns to person table
DataColumn id = people.Columns.Add( "ID", typeof(Int32) );
id.AutoIncrement = true;
people.PrimaryKey = new DataColumn[]{ id };
people.Columns.Add( personname );
people.Columns.Add( personAge );

// Add tables to the DataSet
datadoc.Dataset.Tables.Add( people );

// Create new Row
DataRow mark = people.NewRow();
mark[personname] = "Mark";
mark[personAge] = 18;
people.Rows.Add( mark );

// commit changes
dataset.AcceptChanges();
try
{
StreamWriter writer = new StreamWriter( strPersonSchema );
datadoc.DataSet.WriteXmlSchema( writer );
if( writer != null )
writer.Close();
}
catch( Exception Err )
{
MessagBox.Show( Err.Message.ToString() );
}

Could you tell us what you're hoping it will do, and in what way it
fails to do that?
