c\#重载++

Function overloading allows [functions][] in computer languages such as C, C++, and [C\#][C] to have the same name with different parameters. Operator overloading allows operators to work in the same manner. In C\#, method overloading works with two methods that accomplish the same thing but have different types or numbers of parameters.

函数重载允许[功能][functions]在计算机语言，例如C，C ++和[C＃][C]具有与不同的参数相同的名称。 操作员重载允许操作员以相同的方式工作。 在C＃中，方法重载与两个完成相同任务但具有不同类型或数量参数的方法一起使用。

## 函数重载的例子 **(** An Example of Function Overloading **)** ##

Rather than have a differently named function to sort each type of array, such as:

而不是使用其他函数来对每种类型的数组进行排序，例如：

You can use the same name with different parameter types as shown here:

您可以将相同的名称用于不同的参数类型，如下所示：

The [compiler][] is then able to call the appropriate function depending on the [parameter][] type. Overload resolution is the term given to the process of selecting the appropriate overload function.

然后， [编译器][compiler]可以根据[参数][parameter]类型调用适当的函数。 过载分辨率是指选择适当的过载功能的过程的术语。

## 运算符重载 **(** Operator Overloading **)** ##

Similar to function overloading, operator overloading allows programmers to redefine operators such as +, - and \*. For example, in a [class][] for complex numbers where each number has a real and imaginary part, overloaded operators allow code such as this to work:

与函数重载类似，运算符重载允许程序员重新定义+，-和\*等运算符。 例如，在复数[类][class]中，每个数字都有一个实部和虚部，重载运算符允许这样的代码起作用：

As long as + is overloaded for the type complex.

只要+对于复合类型重载。

## 编写代码时重载的优点 **(** Advantages of Overloading When Writing Code **)** ##

*  You end up with code that is easier to read
    
    您最终得到的代码更易于阅读
 *  Overloading is convenient and intuitive
    
    重载方便直观
 *  Avoids clunky syntax 
    
    避免笨拙的语法
 *  Consistency in naming and notation
    
    命名和符号一致
 *  Works well in templates and other constructs when you don't know the variable type at the time you are writing the code.
    
    当您在编写代码时不知道变量类型时，可以在模板和其他构造中很好地工作。
