There have always been a few different ways of dealing with strings of text in C#, depending on what we need we might use any of the following;
string normalString = "This is a string, to include a line break we need to escape it like this \n so it doesn't terminate the string";
string verbatimString = @"This is a verbatim string where we can type enter
and the string contains the line break";
If we want to include variables in our string we have a few options again;
int x = 5;
string concatenation = "We can do this " + x " to include the variable";
string format = string.Format("We can do this {0} to include the variable", x);
string interpolate = $"We can do this {x} to include the variable";
The two interesting ones here are verbatim and interpolated strings.
If we need to build a multiline string with variables, perhaps from a template we can combine them like this.
var name = "Simon";
var templateName = "How to interpolate a verbatim string";
var now = DateTime.UtcNow;
var output = $@"Hi {name},
This template is a demo of {templateName}.
It was ran at {now.ToString("o")}";
The output of the above demo is
Hi Simon,
This template is a demo of How to interpolate a verbatim string.It was ran at 2017-04-11T14:46:09.5032168Z
For populating large multiline templates the ability to combine string interpolation with the formatting of verbatim string can be extremely useful
