拧一个类似.ToString()的方法 [英] Wring a method like .ToString()

问题描述

大家好，

我想要像.ToString()
这样的方法
说int i = 100;

如果i.ToCustomInt();
那么"i"的输出应显示105(i +某个常数(5)，然后输出将为105)；

我尝试使用密封的类和静态方法"ToCustomInt()".
想知道如何在静态方法中获取该"i"值..

Hi to all,

I would like to have method like .ToString()

say int i=100;

if i.ToCustomInt();
then out put of "i" should show 105(i+some constant value(5) then out put would be 105);

i tried to have sealed class and static method "ToCustomInt()".
wondering how to get that "i" value inside of the static method..

is there any suggestion please.

我同意Om Prakash Pant，这是扩展方法的工作.

这是一个例子

I gree with Om Prakash Pant, this is a job for an extension method.

Here is an example

public static class IntExtensions
{
    public static int ToCustomInt(this Int32 i)
    {
        return i + 5;
    }
}
