Why do i need to create an instance of Random class, if i want to create a random number between 1 and 100 ....like
Random rand = new Random(); rand.Next(1,100);
Is there any static function of Random class to do the same? like...
Random.Next(1,100);
I don't want to create an instance unnecessarily
Next() method in C# is used to return a non-negative random integer.
Next() Returns a non-negative random integer.
The Random class in C# provides defined methods that generate random integers. The most widely used method to generate random integers from the Random class is Next() . The Random.
To generate random numbers in C#, use the Next(minValue, MaxValue) method. The parameters are used to set the minimum and maximum values. Next(100,200); We have set the above method under Random() object.
It is best practice to create a single instance of Random
and use it throughout your program - otherwise the results may not be as random. This behavior is encouraged by not creating a static function.
You shouldn't worry about "creating an instance unnecessarily", the impact is negligible at best - this is the way the framework works.
