How to constantly rename a file and move it

Question

I am trying to constantly rename and move an image to another folder. This folder is used for database so i am trying to store all the images inside this folder . Thus, i needed to rename each image constantly so they will not overwrite each other. (Some renaming convention : images.jpg, images1.jpg, images2.jpg)

I saw the move method but it doesn't let me constantly change the file name and maybe use a for loop to loop it. However, if i am going to detect if the images already exist and move on to a new name? ( Example : images1.jpg already exist but the program is going to replace it.)

Any idea how to work around this?

Use this:

var files = new List<string>();

foreach (var file in Directory.GetFiles(@"Your Location"))
{
    var fileName = Path.GetFileNameWithoutExtension(file);

    if (fileName.StartsWith("Image"))
    {
        files.Add(fileName.Replace("Image",""));
    } 
}

var last = int.Parse(files.OrderByDescending(f => f.ToString()).First()) + 1;

To get the next index available, then just move it to where ever you need
