Is it possible to pass interpolated strings as parameter to a method in C#?

Is it possible to pass interpolated strings as parameter to a method in C#?

Yes, it is possible to pass interpolated strings as a parameter to a method in C#. Interpolated strings are a feature of C# that allow you to embed expressions inside string literals using the $ symbol. Here's an example of how to pass an interpolated string as a parameter to a method:

static void LogMessage(string message)
{
    Console.WriteLine(message);
}

// Pass an interpolated string as a parameter to the LogMessage method
string username = "John";
LogMessage($"User {username} logged in.");

In this example, we define a LogMessage() method that takes a string parameter and writes the string to the console. We then declare a username variable and pass an interpolated string as a parameter to the LogMessage() method. The interpolated string includes the value of the username variable inside curly braces, and the value is substituted into the string at runtime.

When the LogMessage() method is called, it receives the interpolated string as a parameter and writes the string "User John logged in." to the console. The interpolated string is evaluated at runtime, so the value of the username variable is included in the string.

By using interpolated strings as parameters, you can easily pass complex messages to methods and customize the output based on runtime values.
