shorthand If Statements: C#
Just a quick one, Is there anyway to shorthand this?
It's basically determining the direction left or right, 1 for left, 0 for right
In C#:
if (column == 0) { direction = 0; }
else if (column == _gridSize - 1) { direction = 1; }
else { direction = rand.Next(2); }
The statement following this will be:
if (direction == 1)
{
// do something
}
else
{
// do something else
}
If there isn't, it doesn't really matter!开发者_C百科 just curious:)
To use shorthand to get the direction:
int direction = column == 0
? 0
: (column == _gridSize - 1 ? 1 : rand.Next(2));
To simplify the code entirely:
if (column == gridSize - 1 || rand.Next(2) == 1)
{
}
else
{
}
Use the ternary operator
direction == 1 ? dosomething () : dosomethingelse ();
Yes. Use the ternary operator.
condition ? true_expression : false_expression;
Recently, I really enjoy shorthand if else statements as a swtich case replacement. In my opinion, this is better in read and take less place. Just take a look:
var redirectUrl =
status == LoginStatusEnum.Success ? "/SecretPage"
: status == LoginStatusEnum.Failure ? "/LoginFailed"
: status == LoginStatusEnum.Sms ? "/2-StepSms"
: status == LoginStatusEnum.EmailNotConfirmed ? "/EmailNotConfirmed"
: "/404-Error";
instead of
string redirectUrl;
switch (status)
{
case LoginStatusEnum.Success:
redirectUrl = "/SecretPage";
break;
case LoginStatusEnum.Failure:
redirectUrl = "/LoginFailed";
break;
case LoginStatusEnum.Sms:
redirectUrl = "/2-StepSms";
break;
case LoginStatusEnum.EmailNotConfirmed:
redirectUrl = "/EmailNotConfirmed";
break;
default:
redirectUrl = "/404-Error";
break;
}
