On console.writeLine() in c#.net

Question

What is the meaning of this Console.WriteLine( {0} {1}  amount equals amount); {0} and {1} can anyone Explain me. Thank you

Nitin Sontakke · Answer

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.
