过载运算符<< [英] overload operator<<

问题描述

是否可以重载<< c＃中的运算符类似于它的方式

是用c ++完成的？


MyTable table = new MyTable（）;

MyTableRow row = new MyTableRow（）;

row<< new MyTableCell（" cell1 text contents"）;

row<< new MyTableCell（" cell2 text contents"）;

table<<行;


谢谢，


-Steve

is it possible to overload the << operator in c# similar to the way it
is done in c++ ?

MyTable table = new MyTable( ) ;
MyTableRow row = new MyTableRow( ) ;
row << new MyTableCell( "cell1 text contents" ) ;
row << new MyTableCell( "cell2 text contents" ) ;
table << row ;

thanks,

推荐答案

似乎可以重载以下任何二元运算符：


+ - * /％& | ^<< >> ==！=> < > =< =


希望这会有所帮助，

It seems possible to overload any of the following binary-operators:

+ - * / % & | ^ << >> == != > < >= <=

Hope this helps,

信任但验证，对吗？我很感激帮助！


我认为它不会像我想要的那样工作。我收到编译错误

说运算符的第一个参数<<必须是一个int。如上所示，

的位置向左移动。


有趣的是为什么语言不允许完全像运算符这样的c ++

重载。这真是一个很好的功能。


谢谢，

trust but verify, right? I appreciate the help!

I dont think it will work the way I want it to. I got a compile error
saying the first argument for operator<< had to be an int. as in, the
number of positions to shift to the left.

Funny why the language does not allow full c++ like operator
overloading. It really is a good feature.

thanks,

来自MSDN：C＃与C ++重载


与C ++相比，C＃允许重载更少的运算符。有两套

套的限制。首先，成员访问，成员调用（即，

函数调用），赋值和new不能超载，因为运行时定义了这样的操作。


其次，运营商如&&，" || "，"？："和复合

赋值运算符，例如" + ="不能超载，因为增加的

复杂性不值得获益。

From MSDN: C# vs. C++ Overloading

Compared to C++, C# allows overloading of fewer operators. There are two
sets of restrictions. First, member access, member invocation (that is,
function calling), assignment, and "new" cannot be overloaded because such
operations are defined by the runtime.

Second, operators such as "&&", "||", "?:", and compound
assignment operators such as "+=" cannot be overloaded because the added
complexity is not worth the benefit.
