I made program in C# that generates random license keys with 24,25,26,27,28,29,30 characters lenght.How to make 100 random keys with 24,25,26,27,28,29,30 characters lenght?

Are you asking how to generate 100 keys with a random length? 100 keys of each length? Something else?

I want 100 random keys with of each lenght?

For example:

var keysByLength = new Dictionary<int, string[]>();

for (var length = 24; length <= 30; length++)
{
    keyByLength.Add(length, Enumerable.Range(1, 100).Select(n => GetKeyOfLength(length)).ToArray());
}
