Important noteImportant

The XmlSchemaCollection class is obsolete in the .NET Framework version 2.0 and has been replaced by the XmlSchemaSet class.

The following example checks to see if a schema is in the collection. If it is, it displays the schema.

if (xsc.Contains("urn:bookstore-schema"))
{
  XmlSchema schema = xsc["urn:bookstore-schema"];
  StringWriter sw = new StringWriter();
  XmlTextWriter xmlWriter = new XmlTextWriter(sw);
  xmlWriter.Formatting = Formatting.Indented;
  xmlWriter.Indentation = 2;
  schema.Write(xmlWriter);
  Console.WriteLine(sw.ToString());
}
