推荐答案

是因为Exception 拼写为"c" ...

That is because Exception is spelled with a ''c''...

首先是throw，然后是try至catch！开个玩笑:)
语法看起来正确.但是，您需要使用

First throw and then try to catch it! Just kidding :)
The syntax looks correct. However, you need to use

catch(System.Exception ex)

或使用

using System;

在文件开头输入span class ="code-keyword">.可以在错误语句本身中看到此提示.
找不到类型或名称空间名称"Exeption"(您是否缺少using指令或程序集引用?)
希望这会有所帮助.

还应注意，Exception拼写错误.

in the beginning of your file. This hint can be seen in the error statement itself.
The type or namespace name ''Exeption'' could not be found (are you missing a using directive or an assembly reference?)
Hope this helps.

Also noted that Exception is misspelled.
