Quick Log- Question

Quick question,

im using the method LogToFile, but i want, that every log it does goes into a new File.
and not everything in 1 file. How?

Code:

foreach (var value in data)
    LogToFile("Example",  Convert.ToString(value), this);

 

for example:
for (int i = 0; i<5; i++)
LogToFile($"Example-{i}", Convert.............)
