![]() To make it more complex, you can add special characters and mix them up.įor us, we will combine the two methods - RandomNumber and RandomString. StringBuilder builder = new StringBuilder() Ĭh = Convert.ToChar(Convert.ToInt32(Math.Floor(26 * random.NextDouble() + 65))) Ī random password can simply be a combination of a random string and a random number. Public string RandomString(int size, bool lowerCase) If second parameter is true, the return string is lowercase Generate a random string with a given size and case. ![]() The second parameter of the RandomString method is used for setting if the string is a lowercase string. The following code snippet in Listing 2 generates a random string with a given size. The following code in Listing 1 returns a random number. The Next method returns a random number, NextBytes returns an array of bytes filled with random numbers, and NextDouble returns a random number between 0.0 and 1.0. The Random class has three public methods - Next, NextBytes, and NextDouble. It takes either no value, or it takes a seed value. The Random class constructors have two overloaded forms. The code snippet in this article is an example of how to generate random numbers and random strings and combine them to create a random password using C# and.
