DataSet.GetXmlSchema Method

Returns the XML Schema for the XML representation of the data stored in the DataSet.

Namespace: System.Data
Assembly: System.Data (in system.data.dll)

public string GetXmlSchema ()
public String GetXmlSchema ()
public function GetXmlSchema () : String
Not applicable.

Return Value

String that is the XML Schema for the XML representation of the data stored in the DataSet.

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() );
}
