Extended Description
This code analyzer detects the usage of Exists
from the standard Directory
class found in the System.IO
namespace.
Using Directory.Exists()
, path neutralization doesn't take place to ensure that we have the correct absolute path. This causes some of the filesystem operations to operate on files, which are located in the wrong place, and, therefore, errors throw about a target not being found.
A solution to this problem was made with FolderExists()
, because it takes care of the absolute paths and tries to reduce this kind of error caused by passing relative directories to the arguments.
