Question

How could i convert data from string to long in C#?

I have data

String strValue[i] ="1100.25"; 

now i want it in

long l1; 

Answer 1

If you want to get the integer part of that number you must first convert it to a floating number then cast to long.

long l1 = (long)Convert.ToDouble("1100.25"); 

You can use Math class to round up the number as you like, or just truncate...

• Math.Round
• Math.Ceil

Answer 2

You can also use long.TryParse and long.Parse.

long l1; l1 = long.Parse("1100.25"); //or long.TryParse("1100.25", out l1);
