Repeating the same character many times

It can be helpful while testing length of string and we need to have text contains e.g. 256 chars.
In order to prepare that sample text we can use the string constructor that accepts a char and the number of times to repeat it.

new string(char c, int count)

For example, to repeat a letter ‘A’ 256 times:

string result = new String('A', 256);
