As the colon (":") has special meaning in an interpolation expression item, to use a conditional operator in an interpolation expression, enclose that expression in parentheses. string name = "Horace"; int age = 34; Console. WriteLine($"He asked, \"Is your name {name}?\ ", but didn't wait for a reply :-{{"); Console.
Syntax of string interpolation starts with a '$' symbol and expressions are defined within a bracket {} using the following syntax. Where: interpolatedExpression - The expression that produces a result to be formatted.
In computer programming, string interpolation (or variable interpolation, variable substitution, or variable expansion) is the process of evaluating a string literal containing one or more placeholders, yielding a result in which the placeholders are replaced with their corresponding values.
An interpolated verbatim string starts with the $ character followed by the @ character. Starting with C# 8.0, you can use the $ and @ tokens in any order: both $@"..." and @$"..." are valid interpolated verbatim strings. To include a brace, "{" or "}", in a result string, use two braces, "{{" or "}}".
Dart supports string interpolation
var seconds = 5; print("Send $seconds seconds ago"); var harryLikes = 'Silvia'; var otherName = 'Erik'; var otherLikes = 'Chess'; print("Harry like $harryLikes"); print("I think $otherName like $otherLikes"); Also more complex expressions can be embedded with ${...}
print('Calc 3 + 5 = ${3 + 5}'); The number types and the intl package provide more methods to format numbers and dates.
