ExportOptions
Examples
The following example creates an instance of the ExportOptions class and adds a type (Possessions) to the collection returned by the KnownTypes property.
The XsdDataContractExporter then exports the schemas of the types, including the Possessions type added to the collection.

using System.Xml;
using System.Runtime.Serialization;
using System.Xml.Schema;
public class Program
{
public static void Main()
{
try
{
ExportXSD();
}
catch (Exception exc)
{
Console.WriteLine("Message: {0} StackTrace:{1}", exc.Message, exc.StackTrace);
}
finally
{
Console.ReadLine();
}
}
static void ExportXSD()
{
XsdDataContractExporter exporter = new XsdDataContractExporter();
if (exporter.CanExport(typeof(Employee)))
{
exporter.Export(typeof(Employee));
Console.WriteLine("number of schemas: {0}", exporter.Schemas.Count);
Console.WriteLine();
XmlSchemaSet mySchemas = exporter.Schemas;
XmlQualifiedName XmlNameValue = exporter.GetRootElementName(typeof(Employee));
string EmployeeNameSpace = XmlNameValue.Namespace;
foreach (XmlSchema schema in mySchemas.Schemas(EmployeeNameSpace))
{
schema.Write(Console.Out);
}
}
}
static void GetXmlElementName()
{
XsdDataContractExporter myExporter = new XsdDataContractExporter();
XmlQualifiedName xmlElementName =myExporter.GetRootElementName(typeof(Employee));
Console.WriteLine("Namespace: {0}", xmlElementName.Namespace);
Console.WriteLine("Name: {0}", xmlElementName.Name);
Console.WriteLine("IsEmpty: {0}", xmlElementName.IsEmpty);

Remarks
The XsdDataContractExporter is used to generate XSD schemas from a type or assembly. You can also use the XsdDataContractImporter to generate .NET Framework code from a schema document.
For more information about importing and exporting schemas, see Schema Import and Export and Exporting Schemas from Classes.
The KnownTypes property is used by the DataContractSerializer to include types that can be read in an object graph. For more information about the data contract and known types, see Data Contract Known Types.
For more information about data contracts, see Using Data Contracts.
Constructors
| ExportOptions() |
