C＃if else快捷方式

Question

In C# how can I express the following if else statement using a shorter method(with ?):

 if (condition1 == true && count > 6)
           {
               dothismethod(value);

           }
           else if (condition2 == false)
           {

               dothismethod(value);
           }

My code looks really messy with these statements. Can someone direct me to a good resource on if then else short cut syntax?

Answer 1

It sounds like you're trying to write

if ((condition1 && count > 6) || !condition2)
    SomeMethod();

Answer 2

? is not a "shortcut" if/else. It's called a ternary operator , and it's used when you want to assign a value to some variable based on a condition, like so:

string message = hasError ? "There's an error!" : "Everything seems fine...";

Answer 3

Your can write it like:

if ((condition1 == true && count > 6) || condition2 == false)
{
    dothismethod(value);
}

But personally, I would define your first expression as another variable, so your if statement becomes clearer:

bool meaningfulConditionName = (condition1 == true) && count > 6;
if (meaningfulConditionName || !condition2)
{
    dothismethod(value);
}

Answer 4

The conditional operator ? only works for value assignment. But you can definitely fold both if's into one since the result is the same for both:

if ((condition1 == true && count > 6) || condition2 == false)
           {
               dothismethod(value);
           }

Or even more concise as:

if ((condition1 && count > 6) || !condition2) dothismethod(value);
