Question

In my project I have a text box. I assume user type in it float variable or text.
If user types in it float variable I need to check this variable if it is actually a float type!.

I guess some how return true or false from float.Parse(String). Is it possible?!

Answer 1

Instead of Parse, use TryParse – it will return false if it couldn’t parse.

float f;

if(float.TryParse(txtBox.Text, out f))
{
  // success! Use f here
}
