DataSet.GetXmlSchema Method

Calling this method is identical to calling WriteXmlSchema, except that only the primary schema is written.

GetXmlSchema returns XML as a string, and therefore requires more overhead than WriteXmlSchema to write XML to a file.

If you build a DataSet using schema inference and serialize it using XML or Web services, the column ordering may change.

The following example creates a DataSet and DataTable, and then displays the schema in XML format.

private static void DemonstrateGetXml()
{
    // Create a DataSet with one table containing  
    // two columns and 10 rows.
    DataSet dataSet = new DataSet("dataSet");
    DataTable table = dataSet.Tables.Add("Items");
    table.Columns.Add("id", typeof(int));
    table.Columns.Add("Item", typeof(string));

    // Add ten rows.
    DataRow row;
    for(int i = 0; i <10;i++)
    {
        row = table.NewRow();
        row["id"]= i;
        row["Item"]= "Item" + i;
        table.Rows.Add(row);
    }

    // Display the DataSet contents as XML.
    Console.WriteLine( dataSet.GetXml() );
}
