Is there a function to generate the filename of a copied file?

Question

Does C# have any functions to produce a new name for a copied item ?
For example , if I have a string called "Folder" , I need a function to produce a string "Copy of Folder".... and given the string "Copy of Folder" the function should produce "Copy of Folder (1)" and so on ....

Answer 1

You can write a loop, like this:

string baseName = @"C:\Parent\Copy of Folder", actualName = baseName;
int index = 0;

while(File.Exists(actualName) || Directory.Exists(actualName))
    actualName = baseName + " (" + (++index) + ")";

Depending on your use-case, you should probably put this in a static utility method.
