|RandomStringAlphaNumericString Method (IRandom, Int32, RandomStringCasing, Char, Single)|
Generates a random string using only decimal digits and letters from the English alphabet, plus a separator character which can occur randomly with a specified probability.

public static string AlphaNumericString(
this IRandom random,
- Type: Experilous.MakeItRandomIRandom
The pseudo-random engine that will be used to generate bits from which the return value is derived.
- Type: SystemInt32
The length of the string to be generated.
- Type: Experilous.MakeItRandomRandomStringCasing
The letter casing used for English letters.
- Type: SystemChar
The separator character to be randomly inserted into the string according to the probability specified.
- Type: SystemSingle
The probability of any specific index in the string being a separator character. Must be in the range [0, 1].
A random string, with each character being a uniformly random selection from the set of decimal digits and English letters.
In Visual Basic and C#, you can call this method as an instance method on any object of type IRandom
. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic)
or Extension Methods (C# Programming Guide)
The generated string is guaranteed to not start with the separator character, and it is further guaranteed that
two separator characters will never be generated one immediately after the other, regardless of the separator probability.
A separator probability of 0 will guarantee that there are no separators at all, while a probability of 1 will guarantee
that every second character is a separtor character. Probabilities less than 1 but greater that 0.5 will be biased toward the
same every-other character outcome, but will have a chance of generating longer sequences of non-separator characters, rather than
being strictly limited to one non-separator character at a time.
