Answer 1

You should find the index of the space right before the 200 index. So search for all occurrences and then pick the index of the one the closest to 200. Then use this index to do a Substring and you should be good to go

string myString = inputString.Substring(0, 200);

int index = myString.LastIndexOf(' ');

string outputString = myString.Substring(0, index);
