c# - try catch finally block 是如何工作的？

Question

在 C# 中，try catch finally block 是如何工作的？

所以如果有异常，我知道会跳转到catch block ，然后跳转到finally block 。

但是如果没有错误，catch block 不会运行，但是 finally block 会运行吗？

Answer 1

是的，无论是否有异常，finally block 都会运行。

Try
    [ tryStatements ]
    [ Exit Try ]
[ Catch [ exception [ As type ] ] [ When expression ]
    [ catchStatements ]
    [ Exit Try ] ]
[ Catch ... ]
[ Finally
    [ finallyStatements ] ] --RUN ALWAYS
End Try
