| C# 代码 | 等效的 Tea 代码 | 不同的原因 |
|---|---|---|
| using 名字空间; | import 包; | 叫法不同 |
| namespace A{} | module A; // 一个文件只能用一次 | |
| extern alias s; s::System.IO.File; | import module as s; s.File | |
| internal | （无） | |
| A a = new A(1) {p = 4, t = 2}; | A a = new A(1)..p = 4..t = 2; | |
| foreach(int item in arr){ } | for(int item in arr){ } | |
| switch { case 1: case 2: {break;} default: {break;} } | switch { case 1, 2: {} case else: {} } | |
| using(A a = new A()){} | with(A a = new A()) {} | |
| fixed(int* p = &r){ } | with(int* p = &r){ } | |
| var a = fn(); dynamic b = 4; | var a = fn(); object b = 4; | |
| int? a = null; int? b = a ?? 4; | （无） | |
| int[] a = {1, 2, 3}; var list = new List{1, 2, 3}; | int[] a = [1, 2, 3]; var list = [1, 2, 3] as List; | |
| var fn = (e) => { return e + e }; | var fn = (e) -> { return e + e }; | |
| class QAttribute : Attribute {} class A { | lass QAnnotation : Annotation {} class A { | |
| static class AExtensions { void fn(this A a); } | extend A { void fn(); } | |
| class A{ public static A operator +(A a, A b) {} public static explicit operator B(A a) {} } | class A{ A this +(A b) {} as B() {} } |
