string[] files = Directory.GetFiles(ofd.SelectedPath);
System.IO.Path.GetFileNameWithoutExtension(files);
So, I get an error saying:
Cannot convert from 'string[]' to 'string'
Is there any way I can Fix this?

Path.GetFileNameWithoutExtension Method accepts one parameter - string path, which is the path of the file (and it is string not string[]).
In order to get all file names inside that directory, write something like this:
string[] files = Directory.GetFiles(ofd.SelectedPath);
string[] fileNames = files.Select(f => System.IO.Path.GetFileNameWithoutExtension(f)).ToArray();
//or just
//string[] fileNames = files.Select(System.IO.Path.GetFileNameWithoutExtension).ToArray();
or simply iterate over files and get your file names (using for, foreach or any other loop you would prefer):
string[] files = Directory.GetFiles(ofd.SelectedPath);
List<string> fileNames = new List<string>();
foreach(string file in files)
{
fileNames.Add(System.IO.Path.GetFileNameWithoutExtension(file));
}

The files is an array of string and GetFileNameWithoutExtension accepts a parameter of type string. You need to iterate through files via forach or with LINQ, something like this:
var result = files.Select(System.IO.Path.GetFileNameWithoutExtension);
Or:
string[] result = files.Select(System.IO.Path.GetFileNameWithoutExtension).ToArray();
Just make sure that you have added the using System.Linq; to your using directives.

The Output of that comes up with " String[] "

Yeah, but
ofd is very likely an OpenFileDialog, so is probably one element in the array.

@MatinPlays Yes. This will iterate through all files and will apply the
GetFileNameWithoutExtension to all of them as you wanted.Salah Akbari
@MatinPlays You can also use
ToArray in order to get the result as string[]. Have a look at my updated answer to know how.According to that GetFileNameWithoutExtension function doc it requires a parameter of type string but you are passing a string[] to that method.
If you expect that array to contain only one element, you can call that function this way.
string fileName = System.IO.Path.GetFileNameWithoutExtension(files[0]);

@Martin no it doesn't.
System.IO.Path.GetFileNameWithoutExtension(files) expects a string not an array of strings (string[]).
If you want to remove the extension from all filenames in the files array you could use LINQ:
string[] files = Directory.GetFiles(ofd.SelectedPath);
var filesWithoutExtension = files.Select(f =>
System.IO.Path.GetFileNameWithoutExtension(f));
GetFileNameWithoutExtensiontakes a single filename.GetFilesreturns an array (i.e. many).
