Setting Multivalued Properties (WebDAV)

Topic Last Modified: 2006-06-12

The following WebDAV PROPPATCH Method request sets the expected-content-class Field of a folder to urn:content-classes:message and urn:content-classes:item content classes and the custom content class urn:contentclasses:myclass1.

See Constructing Exchange Store HTTP URLs and Authentication and Security Using WebDAV for more information.

This topic contains Microsoft® Visual Basic® Scripting Edition (VBScript), Microsoft C#, and Visual Basic .NET code examples.

Example

PROPPATCH /public/docs/ HTTP/1.1
Content-Type: text/xml;   charset="UTF-8"

<?xml version="1.0"?>
<a:propertyupdate xmlns:a="DAV:" xmlns:d="urn:schemas-microsoft-com:exch-data:"
  xmlns:b="urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/" xmlns:c="xml:">
  <a:set>
    <a:prop>
      <d:expected-content-class b:dt="mv.string">
             <c:v>urn:content-classes:message</c:v>
             <c:v>urn:content-classes:myclass1</c:v>
             <c:v>urn:content-classes:item</c:v>
      </d:expected-content-class>
