How to remove newline in C# line?

Question

C++ / C#

Hello.
The response comes from the server as a string.
For example: 100
11.
I don't know the length before the line break, it all depends on the server's response.
I need to remove the hyphen or replace it with another character.
I tried like this, but it doesn't work:
str = str.Replace(Environment.NewLine, " ");

Answer 1

A string containing "\r\n" for non-Unix platforms,...
Try searching for "\n"
