c# - How to delete every 2nd character in a string?

How to delete every 2nd character in a string?

For example:

3030313535333635  -> 00155365
3030303336313435  -> 00036145
3032323437353530  -> 02247550

The strings are always 16-characters long and the result is always 8 characters long - and the character that is being removed is always a '3' - Don't ask why however - I did not dream up this crazy source data.

Try this to get the every other character from the string:-

 var s = string.Join<char>("", str.Where((ch, index) => (index % 2) != 0));
