Question

I am trying to do somthing like this:

  // some code...

  string a="aa";
  string b="bb";
  // ...
  if(b>a)    // suppose to be true
   {
     // do somthing
   }

But then I get the compile error:

Operator ‘>’ cannot be applied to operands of type ‘string’ and
‘string’.

So what is the best approach?

Answer 1

Use CompareTo() method instead of.

if(b.CompareTo(a) > 0)

Compares two specified String objects and returns an integer that
indicates their relative position in the sort order.

This method ;

• if b is greater than a or a is null, it returns greater than zero.
• if b is less than a, it returns less than zero.
• if b has the same position in the sort order as a, it returns 0.
