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

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.

NoteNote

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

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() );
