How to escape braces (curly brackets) in a format string in .NET?

 

In .NET, you can escape braces (curly brackets) in a format string by using double braces. That is, you use {{ to represent an opening curly brace {, and }} to represent a closing curly brace }. Here's an example:

csharp

using System;

class Program
{
    static void Main()
    {
        string name = "John";
        int age = 30;

        // Using double braces to escape curly braces in the format string
        string formattedString = $"{{Hello, my name is {name}. I am {age} years old.}}";

        Console.WriteLine(formattedString);
    }
}

In this example:

• We have a format string enclosed in double braces: "{{...}}".

• Inside the format string, we include placeholders like {name} and {age} for string interpolation.

• When we run the program, it will print the following output:

  csharp

• {Hello, my name is John. I am 30 years old.}
  

By using double braces, you can include literal curly braces within a format string without them being interpreted as placeholders for string interpolation.
