How can I get a character in a string by index?
I know 开发者_JAVA技巧that I can return the index of a particular character of a string with the indexof()
function, but how can I return the character at a particular index?
string s = "hello";
char c = s[1];
// now c == 'e'
See also Substring
, to return more than one character.
Do you mean like this
int index = 2;
string s = "hello";
Console.WriteLine(s[index]);
string also implements IEnumberable<char>
so you can also enumerate it like this
foreach (char c in s)
Console.WriteLine(c);
