How to generate random letters in C# using the Random class?

In C#, you can use the Random class to generate random letters. Here is an example code:

Random random = new Random();
int randomNumber = random.Next(0, 26); // 生成0到25之间的随机整数
char randomLetter = (char)('A' + randomNumber); // 将随机整数转换为字母

Console.WriteLine(randomLetter); // 输出随机字母

This example code will generate a random integer, then convert it to a letter. Since the ASCII code for ‘A’ is 65, we can simply add 65 to the random integer to get the corresponding letter.
