Multiline C# interpolated string literal

Multiline C# interpolated string literal

In C#, you can create multiline interpolated string literals by using the $ symbol before the opening double-quote and then inserting line breaks (\n) where needed. Here's an example:

string multilineString = $@"This is a multiline string with {Environment.NewLine}interpolated values: {1 + 2} ";

In this example, we're using the $ symbol before the opening double-quote to indicate that this is an interpolated string. We're also using the @ symbol to indicate that this is a verbatim string literal, which allows us to include line breaks without using the escape character \.

To insert a line break in the interpolated string, we're using the Environment.NewLine property, which returns the newline string for the current platform ("\r\n" on Windows, "\n" on Unix/Linux).

Finally, we're using curly braces {} to insert an interpolated value (1 + 2) in the string.

This will result in a string with multiple lines and interpolated values:

This is a multiline string with interpolated values: 3
