in vb.net the function val is used to find the value . which function is used in c# to get the value?

Answer 1

use atoi(char) to convert char to int.
use atol(char) to convert char to long.
use atof(char) to convert char to float.

Answer 2

Since C# is a real programing langyuage, you need to know the type you are converting to.

Use one of the functions:
Convert.ToInt32(val)
Convert.ToDouble(val)
Convert.ToString(val)
depending on the type you want to get.

you can search the Convert class for more functions

Answer 3

You could do for instance:

string s = "123";
int n = int.Parse(s);
