C是我最喜欢的，但也很糟糕。

It has the worst pre-processor ever. Why didn't they use something like m4? The whole header vs source file model is broken. Pascal got it right with units. It needs case ranges in the switch statement. Unions and casts from void* break the type system. This makes garbage collectors impossible. No nested functions. GNU C has this, but it should be standard. No boundary checking for allocated memory. There are tools that discover this but they don't detect errors where a piece of code miscalculates an address and writes to an allocated region which isn't related at all. I hate the whole pointer arithmetic. No bounds checking for arrays. Too many issues regarding portability. Even wchar_t differs across platforms.

C#

我对c#非常满意，但这两个真的让我很恼火:

Constructor-based initialization for immutable classes is less convenient, less intuitive (when you read the code you don't understand what you assign to what), has less IDE backing than inline object initialization. This makes you lean towards mutable classes inevitably. I know this has been mentioned before, but I strictly have problems with initialization syntax for immutable classes. switch is too verbose. Whenever I see a situation where a switch would be proper, I'm really inclined to use an if..else if.. just because it's more terse (~30% less typing). I think there should be no fallthrough for switch, break should be implied, and case should allow comma separated list of values.

关于c#:

I hate that there is no keyword to specify which exceptions are thrown from a method like in java. Its a much better way to document exceptions than using an XML comment. I would also want a much better syntax for generic constraints like oring and anding of constraints. Why a method can't return more than one value? Lack of support for aspect oriented programming in the language. Why can't you annotate each one of the property accessors with an attribute? Lack of builtin regexp support like in perl.

我的母语……虽然它听起来比克林贡语更美，但它是一个语法地狱……

conjugations: even regular verbs have different forms for each person and time (with few exceptions)... Example: I see, you see, he/she/it sees, we see, you see, they see translates into: Ich sehe, du siehst, er/sie/es sieht, wir sehen, ihr seht, sie sehen. polite form of address: equals 3rd person plural, used to equal 2nd person plural in the middle age... I really hate the concept of distinguishing between "Du" and "Sie" for my philosophy is that each human being should be considered equal in the amount of respect for it deserves (I mean, what are swear words for, hm?) punctuation: show me a language that uses more commas regularly! missing suitable words: eg. there's no real German equivalent of "convenience" or any derivate of this word... in almost every case you just can't translate it into another German word and keep the meaning... instead you would have to make up a whole subset to describe it somewhat adequate... Anglicisms and Denglish: Sure, the English language has "Kindergarten" or "Poltergeist" and what not but the German language is overflowing with Anglicisms nobody needs... Even worse: We redefine some words we adopt, eg. in German "Handy" means a cell phone and has nothing to do with the adjective it is in English... There are influxes on grammar as well, leading to "Denglish" expressions (see linked article at Wikipedia) There's more, but I don't want to exaggerate this and those are my personal Top5 of what I hate about the German language...

到目前为止，我最讨厌我最喜欢的语言的地方是我的选择总是在变。每次我以为我找到了命中注定的那个人，我就会发现我讨厌他的5个(或更多)地方。然后那边的草看起来更绿……
