Question

Can someone elaborate on the following format string? I don’t completely realize the meaning.

String.Format("{0:#,0.##}", money);

Thanks.

Answer 1

it means that the money have thousand separator(,) and if in decimal values it will be rounded to two digits after decimal, and if there is only decimal values(.256) it will be (0.27)

decimal money=12341257    //output= 12,341,257 
decimal money=1257        //output= 1,257
decimal money=1257.25     //output= 1,257.25
decimal money=1257.2468   //output= 1,257.25
decimal money=.50         //output= 0.50
decimal money=.759        //output= 0.76

Explanation:

 "{0:#,0.##}"
  #,0  //means that , as thousand seperator
  0.## //means that 0 is placed before if only decimal values as .56 to 0.56
  0.## //means if contains decimal then only display 2 digits after decimal
  0.00 //means 2 digits after decimal must be displayed whether or not money contains decimal value
