When i put file.FullName(which is not null i debugged) into an string array some are null and some are not

Question

So let's say as example i have the image path which is "D:\..." anything. file.FullName is this path, but sometimes when i put that path into the array the element is null but i have no idea why.

Let's say i have 100 pictures in the folder then 10 percent of their names are null in the array but i checked in debuggin file.FullName is never null.

Someone has an idea why this happens? Or did i overlook something?

            int z = 0;
            foreach (FileInfo file in Variables.dir.GetFiles())
            {
                try
                {
                    this.myImageList.Images.Add(Image.FromFile(file.FullName));
                    names[z] = file.FullName;
                }
                catch
                {
                    Console.WriteLine("This is not an image file");
                }
                z++;
            }

Answer 1

Your code, even when erroring, is still incrementing z. Move z to within try{} instead of outside the catch{} / finally{} . This will cause z to only increment when the program finds only files that it is looking for / that match your criteria (i.e Image files).

        int z = 0;
        foreach (FileInfo file in Variables.dir.GetFiles())
        {
            try
            {
                this.myImageList.Images.Add(Image.FromFile(file.FullName));
                names[z] = file.FullName;
                z++;
            }
            catch
            {
                Console.WriteLine("This is not an image file");
            }
        }

Your program could be finding hidden files or others when not looking in a debugged file path. Multiple reasons for your code to catch{}, but not certain without adding in:

try{ ... }
catch(Exception ex)
{
    Console.WriteLine("This is not an image file: \n" + ex); 
}

in order to at least get the proper error to further debug
