searchPattern puede ser una combinación de caracteres literales y comodín, pero no admite expresiones regulares. Los siguientes especificadores de caracteres comodín se permiten en searchPattern.

Los caracteres distintos del carácter comodín son caracteres literales. Por ejemplo, la cadena "*t" busca todos los nombres al terminar con la letra "t". ". La searchPattern cadena "s*" busca todos los nombres a path partir de la letra "s".

Este método rellena previamente los valores de las siguientes DirectoryInfo propiedades:

• Attributes

• CreationTime

• CreationTimeUtc

• LastAccessTime

• LastAccessTimeUtc

• LastWriteTime
