We want to insert linebreak character sequences into a string in C#. 

Solution:

The platform safe way of doing this is by using the Environment.NewLine property.

msg = "An error occurred: " + Environment.NewLine + e.Message;

Composing a string with more than one line break can become really messy, so using string.Format might be a good idea.

msg = string.Format("{1} An error occurred!{0}Exception: {0}{2}",
  Environment.NewLine, CurrentTime, e.ToString());
