The term iff is used for "if, and only if"

There is no single keyword or for iff in C#.

What exactly are you trying to implement with the iff statement?

You might need two if statements to achieve your goal.

In some cases, the effect of iff is achieved internally, .e.g.
MyClass myClass = new MyClass();
if (myClass is MyClass)




the is keyword will evaluate to true if and only if the object is of the type MyClass.

If you mean VB IIf statement, there is C# equivalent:

VB: str = IIf(result < 0, "less than", IIf(result > 0, "greater than", "equal to"))
C#: str = ((result < 0) ? "less than" : ((result > 0) ? "greater than" : "equal to"));

On the off chance you meant 'iif':

boolexpr ? expr1 : expr2

If boolexpr is TRUE, the result is expr1, otherwise the result is expr2

C#: str = ((result < 0) ? "less than" : ((result > 0) ? "greater than" : "equal to"));
