1)硬编码包含您想要包含的所有字符的字符串

2)使用单个Random实例(适当的)锁定,如果你是

将从许多线程中使用它)

3)创建一个正确长度的StringBuilder

4)In for循环,使用

Random.Next附加下一个随机字符,传入字符串的长度,并使用字符串's

indexer

5)在StringBuilder上调用ToString

1) Hard-code a string with all the characters you want to include
2) Use a single instance of Random (with appropriate locking if you''re
going to use it from many threads)
3) Create a StringBuilder of the right length
4) In a for loop, append the next random character by using
Random.Next, passing in the string''s length, and using string''s
indexer
5) Call ToString on the StringBuilder
