  In the simplest term, you can call it a placeholder.

   

  So, you have something like this {0}, {1}, {2}, now because you have 3 placeholders, you will pass 3 more values to the function.

   

  These values will be inserted at the place of a placeholder in exact same order as they are passed. This is to avoid complex concatenation logic and an unreadable code.

   

  So instead of:

   

  "Hello " + custName + ", Your invoice number : " + intInvoiceNumer.ToString() + " must be paid by " + dateDueDate.ToString()

   

  You can write:

   

  ("Hello {0}, Your invoice number : {1} must be paid by {2}", custName, intInvoiceNumer, dateDueDate)

   

  You may also look into String.Format function on which above is based.

  it is in this format

  Console.WriteLine(string,object); 

  First argument is string and next is collection ie. object

   

  Example of {0},{1} in C#

  Console.WriteLine("{0}{1}{2} of C# Corner", "I", "am", "author");

   

  output : I am Author of c# corner
