如何在C＃中的程序员定义的部分Array类中使用Array.Sort方法？

Question

Hey everyone I was trying to extended an Array with a user defined method ( MajorityElementOf ) in context of my Program. so I use the following code :

partial class Array{
    public static object MajorityElementOf(int[] arr)
    {
        Array.Sort(arr);
        //rest of the code
    }
}

Compiling this is giving an error:

'Array' does not contain a definition for 'Sort';

It may be due to the Sort method is not defined in this part of Array . Can anyone tell me how to use Array.Sort(arr) method in this code ?

Answer 1

Use

System.Array.Sort(arr);

The problem is that the user defined Array class hides the one in the System namespace.

Answer 2

Your problem is your Array class takes precedence in effect hiding the other class. You can use the full namespace to get around this, for example:

System.Array.Sort(arr);

Answer 3

Problem is you have used same name for class ( Array ), which takes precedence over System.Array as local context/scope get precedence. Try qualifying with namespace.

System.Array.Sort(arr);
