功能: 将if 语句转换为 switch 语句或C# 8.0 switch 表达式。 使用时机: 最好将 if 语句转换为 switch 语句或 switch 表达式,反之亦然。 操作原因: 如果使用 if 语句,通过此重构可将其轻松转换为 switch 语句或 switch 表达式。 操作说明 请将光标置于 if 关键字。 按(Ctrl+.) 触发“快...
As far as I can tell, it seems that you can use the switch and if statements to achieve the same results. Am I missing something, or are they more or less interchangeabl
1. if语句:if语句用于判断条件是否为真,如果条件为真,则执行指定的代码块。if语句的基本形式如下: “`python if condition: # 如果条件为真,则执行这里的代码 statement(s) “` 2. if-else语句:if-else语句可以根据条件的真假来执行不同的代码块。如果条件为真,则执行if代码块;如果条件为假,则执行else代码...
ES.70: Prefer a switch-statement to an if-statement when there is a choice ES.70:进行选择时,switch语句比if语句好 Reason(原因) Readability. 可读性 Efficiency: A switch compares against constants and is usually better optimized than a series of tests in an if-then-else chain. ...
总结 使用if-else-if: 需要进行条件语句而必须使用 需要判断的条件很少时,一般不超过5个 使用switch-case: 能用则用 参考资料 Advantage of switch over if-else statementIf…else…if vs switch…case, difference and usage?switch vs if else
The `if` and `switch` statements provide branching logic in C#. You use `if, `else` and `switch` to choose the path your program follows.

Adam, you are right. Unfortunately, Ayush removed his answer I was referring to. In his answer he basically stated that the switch statement is a "simple" version of the list if statements. This still hold true, so there's a good reason for the switch statement to exist: it simplicity ...
Also note that if you want to do more than one thing inside an if statement, you need to enclose it in curly braces. 1 2 3 4 5 if(something) { do_this(); do_that(); } vs 1 2 3 if(something) do_this_if_something_is_true(); this_will_run_either_way();// not inside if...
