Answer 1

You can use a custom numeric format string:

val.ToString("0.0##")

Answer 2

Hope you like this logic. Please try this.

  double val = 1.002;
  string output = !val.ToString().TrimEnd('0').Contains('.') ? string.Format("{0}.0", val) : val.ToString().TrimEnd('0');

If the value is 1.00, then my output will be 1.0

Then you can convert this string into other data types.
