Lag XSD fra XML i kode

xsd.exe kan gjøre hva du vil:

Følgende kommando genererer et XML-skjema fra myFile.xml og lagrer det i den angitte katalogen.

xsd myFile.xml /outputdir:myOutputDir

Du kan lese mer om det her og her

ELLER

Du kan prøve programmatisk slik:

XmlReader reader = XmlReader.Create(@"yourxml.xml");
XmlSchemaSet schemaSet = new XmlSchemaSet();
XmlSchemaInference schema = new XmlSchemaInference();
schemaSet = schema.InferSchema(reader);

foreach (XmlSchema s in schemaSet.Schemas())
{
    using (var stringWriter = new StringWriter())
    {
        using (var writer = XmlWriter.Create(stringWriter))
        {
            s.Write(writer);
        }

        textbox.text = stringWriter.ToString();
    }
}

Det er dette du går glipp av...i stedet for å bare gjøre s.ToString() , gjør dette:

XmlWriter writer;
int count = 0;
foreach (XmlSchema s in schemaSet.Schemas())
{
    writer = XmlWriter.Create((count++).ToString() + "_contosobooks.xsd");
    s.Write(writer);
    writer.Close();
    Console.WriteLine("Done " + count);
}
reader.Close();

Du kan deretter skrive riktig logikk for å gjøre lesingen/skrivingen mer elegant, lese mange xml-filer og lage tilsvarende xsd-filer osv.

Jeg tok contosobooks.xml herfra:https://code.google.com/p/code4cs/source/browse/trunk/AppCase/dNet/Xml/data/contosoBooks.xml?spec=svn135&r=135

og utdata xsd er:
