❔ How can you create a string that creates random characters?

The most reasonable way would probably be to use a
StringBuilder
You could append a random character to the builder, and repeat that for as many characters you wantIs there any documentation
Or something I can read about it
❯ Class: System.Text.StringBuilder
Represents a mutable string of characters. This class cannot be inherited.
❯ Struct: System.Text.StringBuilder.ChunkEnumerator
Supports simple iteration over the chunks of a StringBuilder instance.
❯ Struct: System.Text.StringBuilder.AppendInterpolatedStringHandler
Provides a handler used by the language compiler to append interpolated strings into StringBuilder instances.

You'll also want to look into the
Random class❯ Class: System.Random
Represents a pseudo-random number generator, which is an algorithm that produces a sequence of numbers that meet certain statistical requirements for randomness.
❯ Class: System.IO.RandomAccess
Provides offset-based APIs for reading and writing files in a thread-safe manner.
❯ Class: System.Security.Cryptography.RandomNumberGenerator
Provides functionality for generating random values.

Okay
You can use faker package https://github.com/bchavez/Bogus to generate fake data, very useful with Unit tests. but maybe to much for your simple need

Is there any tutorials on this like videos?
I'd implement it yourself as a learning exercise
here's some pseudocode
- create an array of possible characters
- create an empty string to target
- instantiate a new instance of Random()
- while the length of the target string is less than desired,
--- create an index int using Random.Next() and the length of the array
--- add the character at the index to the target string
- when length is satisfied, return the string
