Question

I would like to declare (and randomize) about 500 strings.

I believe I have two options here:

1: Create an array with a size of 500.

string[] x = new string[500];

for(int i = 0; i < 500; i++)
{
    x[i] = Randomize_thisString(); // Some routine 
}

2: Declare (and randomize) 500 different strings.

string string_one = Randomize_thisString();
string string_two = Randomize_thisString();
string string_n = Randomize_thisString(); 

...

Which one of these would be the faster method, and does anyone know of a third option here?

Thank you,

Evan

Answer 1

I will go with first choice, since this will just run once and it not takes much time.

An idea on how create a function to generate the random string I will uses System.IO.Path.GetRandomeFileName()
The testing code:

System.IO.Path.GetRandomFileName();

Stopwatch watch = Stopwatch.StartNew();
string[] x = new string[500];

for (int i = 0; i < 500; i++)
{
    x[i] = System.IO.Path.GetRandomFileName();
}

watch.Stop();
Console.WriteLine(watch.ElapsedMilliseconds);

result is 2.
