In c# what does mean “< ? :”? [duplicate]

Answer 1

It's a if statement, using tenary operator. You can read more about it at http://msdn.microsoft.com/en-us/library/ty67wk28(v=vs.80).aspx

Answer 2

It's the conditional operator.

Same as this:

if (a < b)
   return "c" + " ";
else 
   return "text" + " ";

Answer 3

The < operator checks if the left operand is smaller than the right operand.

The ? (Also called the ternary operator) yields, in this case, c if a < b and text otherwise.

Answer 4

if a is greater than b return c + " " else return "text" + " "

Answer 5

This is a Ternary operation (see http://en.wikipedia.org/wiki/Ternary_operation ). Basically, the expression on the left is evaluated. If it evaluates to true, the result is the expression to the left of the :. If it is false, it is the one after.

In your example, if a is less than b, the result is c, otherwise text.

Answer 6

Here a is being compared with b and is evaluated as a boolean,

So if a < b is true then c is returned

in case it evaluates to false then text is returned.

In either case you have a single space returned additionally in the end
