Question

I got a String like:

• "Hello.Test.Trash"

or "Hello.Test.Computer.Trash"

or "Haha.Yeah.Space.Car.Trash"

I want to be able, removing the last word “Trash“, which is always the same including the preceding dot:

"Hello.Test"

"Hello.Test.Computer"

"Hello.Yeah.Space.Car"

What would be the best/cleanest way to do that?

Answer 1

If you have only one occurrence of ‘.Trash’ at the end:

string value = "Hello.Test.Trash";
string notrash = value.Replace(".Trash","");
// notrash = "Hello.Test"

If ‘.Trash’ can also be in the middle of the string, and you don’t want to replace that:

string value = "Hello.Trash.Test.Trash";
string notrash = Regex.Replace(value, @"\.Trash$", "");
// notrash = "Hello.Trash.Test"
