Remove characters before character "."

Question

How effectively remove all character in string that placed before character "."? Input: Amerika.USA Output: USA

Accepted Answer

You can use the `IndexOf` method and the `Substring` method like so:

```
string output = input.Substring(input.IndexOf('.') + 1);
```

The above doesn't have error handling, so if a period doesn't exist in the input string, it will present problems.
