how to use xsd proof xml-string from xmldocument

[David]

I have a xmldocument like this:

XmlDocument doc = new XmlDocument();
doc.LoadXml(xml-string);

and I have a .xsd file, "schema.xsd ".

How do I use this xsd file to valid the string?
Otherwise how do I trans the doc to XmlTextReader and valid it?
Thanks for any advice, David.

using System;

using System.Xml.Sche ma;
// . . .

private bool isSchemaValid;

// . . .
private void btnValidate_Cli ck( object sender, EventArgs args)
{
// . . .
this.isSchemaVa lid = true;
string targetNamespace URI = "urn:your-schema-com"; // put the target namespace URI of your schema here.
XmlValidatingRe ader reader = new XmlValidatingRe ader( new XmlTextReader( new StringReader( xml_string ) ) );
reader.Schemas. Add( targetNamespace URI, "schema.xsd ");
reader.Validati onEventHandler += new ValidationEvent Handler( xmlDocument1_Va lidationCallBac k);

XmlDocument xmlDocument1 = new XmlDocument( );
xmlDocument1.Lo ad( reader); // this will call Read( ) on the XmlValidatingRe ader, which schema-validates as it loads.
// . . .
// . . . any schema errors will result in the callback method being called while Load( ) processes.
// . . .
Console.WriteLi ne( "\r\n\tSchemaVa lid = " + this.isSchemaVa lid.ToString( ) );
// . . .
}

private void xmlDocument1_Va lidationCallBac k( object sender, ValidationEvent Args args)

isSchemaValid = false;
Console.WriteLi ne( "\r\n\tValidati on Error: " + args.Message );

Thank you very much.

Thank you, Derek.

If I wrote it in .dll and deploy it to another server,
how should I assign the xsd file path in reader.Schemas. Add(
targetNamespace URI, "schema.xsd ")?

Thanks, David.
