asp.net - 如何组合这些 If 语句条件

Question

作为一个整体，我对 OOP 很陌生，更不用说 VB 了。我试图通过组合条件将以下 4 行变成 2 行:

ElseIf GA_URI.StartsWith("/home/index") Then
    gaCategory = cat_splash

ElseIf GA_URI = "/games" Then
    gaCategory = cat_splash

我试过这个:

ElseIf GA_URI.StartsWith("/home/index") And GA_URI = "/games" Then
    gaCategory = cat_splash

但是不工作。非常感谢任何帮助

Answer 1

我建议 OrElse所以你可以更有效地短路(不必评估两个表达式):

ElseIf GA_URI.StartsWith("/home/index") OrElse GA_URI = "/games" Then
   gaCategory = cat_splash

---

更新:

Q: Would this work for more than 2 expressions? as I have cases where I may have 3 or more

当然:

ElseIf GA_URI.StartsWith("/home/index") OrElse 
    (GA_URI = "/games" OrElse GA_URI = "/foo")
Then 
     gaCategory = cat_splash
...

你可以继续(括号表达式)但在某个时候Select...Case将是要走的路。
