If DirectoryInfo contain a Directory

Question

I'm tring the test to see if a DirectoryInfo[] contains a directory my code is below

DirectoryInfo[] test = dir.GetDirectories();
if(test.Contains(new DirectoryInfo(dir.FullName +"\\"+ "Test_Folder")))
{
    ContainsTestFolder = true;
}

To me this should work but it does not seem to return true when it should. Any ideas to what I am doing wrong.

Answer 1

Use Enumerable.Any

DirectoryInfo[] test = dir.GetDirectories();
if (test.Any(r => r.FullName.Equals(Path.Combine(dir.FullName,"Test_Folder"))))
{
   ContainsTestFolder = true;
}

The reason you are not getting the desired result is, Contains compare object reference, not its values. Also consider using Path.Combine instead of concatenating paths.
