Example: Array of class objects. : is not null, the Elvis operator returns it, otherwise it returns the expression to the right.Note that the expression on the right-hand side is evaluated only if the left-hand side is null.. See My Options Sign Up The example you were quoting from uses LINQ to Objects, where the implicit lambda expressions in the query are converted into delegates whereas you're using EF or similar, with IQueryable queryies, where the lambda expressions are converted into expression trees.Expression trees don't support the null conditional operator (or tuples). Short-circuit evaluation, minimal evaluation, or McCarthy evaluation (after John McCarthy) is the semantics of some Boolean operators in some programming languages in which the second argument is executed or evaluated only if the first argument does not suffice to determine the value of the expression: when the first argument of the AND function evaluates to false, the Musician Elvis Presley died at 42 years old on Madonna's 19th birthday i.e. (as in Foo::Bar or a.b) operate not on values, but on names, essentially call-by-name semantics, and their value is a name.

Just to clarify the name: ternary is the type of operator (i.e. The conditional operator ? operator to check if a delegate is non-null and invoke it in a thread-safe way (for example, when you raise an event), as the following code shows:. Latest breaking news from CBS2 WBBM-TV Chicago. Note that the or operator does not return only True or False.

One instance of where this is handy is for returning a 'sensible default' value if an expression resolves to false-ish (as in Groovy truth). You can also use the Elvis operator to return from a function early, as shown in the following example: : g() will set x equal to the result of f() if that result is a true value, and to the result of g() otherwise..
