C中运算符方法的方法名#

这是完整的清单 C# overloadable operators

可以在下面找到运算符元数据/生成的msil名称的列表 Framework Design Guidelines -> Operator Overloads .

有不同的 F# operator overload list .

最后,请参阅 ECMA-335 Common Language Infrastructure (CLI) I.103运算符重载,其中列出了C++/CLI的运算符。

基于 表情 班级:

== op_Equality
!= op_Inequality
>  op_GreaterThan
<  op_LessThan
>= op_GreaterThanOrEqual
<= op_LessThanOrEqual
&  op_BitwiseAnd
|  op_BitwiseOr
+  op_Addition
-  op_Subtraction
/  op_Division
%  op_Modulus
*  op_Multiply
<< op_LeftShift
>> op_RightShift
^  op_ExclusiveOr
-  op_UnaryNegation
+  op_UnaryPlus
!  op_LogicalNot
~  op_OnesComplement
   op_False
   op_True
++ op_Increment
-- op_Decrement

接受的答案很好,因为它链接到可重载运算符的列表,但它没有严格回答问题,因为它在编译时不提供运算符的名称。

第二名的答案包括这一点,但这是一个不完整的列表,而且没有很好的组织。为了完整性起见,我创建了自己的列表,包括一些您可能期望可以重载但不能重载的运算符。该列表按照运算符优先级的顺序排列,从最高(最紧)优先级到最低优先级。

Outside of Order of Operations (used when necessary to coerce types)
   op_Implicit
   op_True
   op_False

Unary (only one operator)
++ op_Increment (Includes preincrement and postincrement)
-- op_Decrement (Includes predecrement and postdecrement)
-  op_UnaryNegation
+  op_UnaryPlus
!  op_LogicalNot
~  op_OnesComplement
   op_Explicit
await (Not overloadable)

Multiplicative
/  op_Division
%  op_Modulus
*  op_Multiply

Additive
+  op_Addition
-  op_Subtraction

Shift
<< op_LeftShift
>> op_RightShift

Relational
>  op_GreaterThan
<  op_LessThan
>= op_GreaterThanOrEqual
<= op_LessThanOrEqual
as (Not overloadable)
is (Not overloadable)

Equality
== op_Equality
!= op_Inequality

And
&  op_BitwiseAnd

Exclusive Or
^  op_ExclusiveOr

Inclusive Or
|  op_BitwiseOr

Conditional And
&& (Not overloadable - use "implicit operator bool" or "operator true")

Contional Or
|| (Not overloadable - use "implicit operator bool" or "operator true")

Null-Coalescing Operator
?? (Not overloadable)

Ternary
?: (Not overloadable - use "implicit operator bool" or "operator true")

Assignment
=  (Not overloadable - for combined operator and assignment (such as +=), just use the operator (+))

注:C编译器首选 implicit operator bool 如果定义了这两个运算符,则不使用“真”和“假”运算符。

根据参考文献 StackOverflow question 以下方法名也由C编译器发出/理解,但是

• 我在Visual Studio 2015和C 6.0中运行了一些测试,试图使它们正常工作,以及
• C 5.0规范列出了“一元(和二进制)运算符函数名的完整集合”(附录A,第469页),这些名称在其中没有出现。

Unary
&   op_AddressOf
*   op_PointerDereference

Binary
.   op_MemberSelection
->  op_PointerToMemberSelection

    op_SignedRightShift
    op_UnsignedRightShift

=   op_Assign
*=  op_MultiplicationAssignment
/=  op_DivisionAssignment
%=  op_ModulusAssignment
-=  op_SubtractionAssignment
+=  op_AdditionAssignment
<<= op_LeftShiftAssignment
>>= op_RightShiftAssignment
|=  op_ExclusiveOrAssignment
&=  op_BitwiseAndAssignment
|=  op_BitwiseOrAssignment

    op_UnsignedRightShiftAssignment
    op_SignedRightShiftAssignment

,   op_Comma
