How can I determine if a subdirectory exists in C#?

In C#, how can one determine if a subdirectory exists?

Is this开发者_如何学编程 neccesary when calling CreateSubDirectory?

if(System.IO.Directory.GetDirectories(path).Length>0)
{
//if this condition is true-->> Directory has sub-sirectories

} 

If the subdirectory already exists, this method does nothing.

Use Directory.Exists to check if it exists http://msdn.microsoft.com/en-us/library/system.io.directory.exists.aspx

Do you need this?

if(Directory.Exists(path)) 
{
     // This path is a directory
     ProcessDirectory(path);
}

Use System.IO.Directory.Exists. MSDN is your friend :)

System.IO.Directory.Exists
