Uniquify is a lightweigth liblary for generating unique strings or numbers.
Install
dotnet add package Uniquify --version 1.0.0
Usage
Uniquify contains several static methods that helps you shape your tokens the way you want.
GetInt64 and GetInt32 methods are useful for generating numbers. Based on your needs you can generate unique long or int types (int type can have a maximum length of 8 and long type can increase this number to 18). They both get an integer type which is responsible for the length of the generated number, and return a number with your specified length. But keep in mind that uniqueness comes from a bigger range, to keep safety of uniqueness, give greater length and work with greater types.
var unique32BitsNumber = Uniquify.GetInt32(4);
var unique64BitsNumber = Uniquify.GetInt64(14);
The GetString method like his other siblings will return an unique string which specific length that you specified. Keep in mind that to keep you safe from StackOverFlow exception The GetString method is limited to 1000 length.
var uniqueString = Uniquify.GetString(18);
var uniqueString = Uniquify.GetString("15987!@#./,?sdafreERTSFDOI", 40);
For the sake of performance is better to instantiate RNGCryptoServiceProvider for your own, if you want to generate thousand of token in a block
using var rngProvider = new RNGCryptoServiceProvider();
for (var i = 0; i < 100; i++)
{
var uniqueString = rngProvider.GetString(10);
var uniqueInt32 = rngProvider.GetInt32(4);
var uniqueInt64 = rngProvider.GetInt64(10);
DoSomething(uniqueString, uniqueInt32, uniqueInt64);
}
