1. how we display the text with format the decimal place of a float or double number?
For example:
3.8456 will result in 3.85 (if we limit the decimal place to 2)

2. how we extract the character from a string?
This is same like the mid(), left(), or right() in Visual Basic.
But in c# we have to use string format? and what is the format string that we should use?

Any help would appreciate.

1.) double beforeRound = 3.8456;
     double afterRound = System.Math.Round(beforeRound ,2)

2.) I use SubString

I recommend to use static method String.Format() instead of rounding the number. Use:
The output is: "formatted number = 3.85"
