Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Represents the minLength
element from XML Schema as specified by the World Wide Web Consortium (W3C). This class can be used to specify a restriction on the minimum length of the data value of a simpleType
element. The length must be greater than the value of the minLength
element.
