How do I check if a directory exists within another directory

Hi,

How do I check if a directory exists within another directory?

For example

C:/aaa C:/Aaa = true
C:/aaa/ C:/Aaa/bb = true
C:/aaa/ C:/Aaa/bb/cc = true
C:/bb/ C:/aa/ = false

Thanks,

Aine

For these simple cases, how about:

if (dir.ToLower().StartsWith (subDir.ToLower()))
{}
