如何重载 PowerShell 内置类的方法 [英] How to overload the PowerShell inbuilt class's methods

问题描述

我可以重载 PowerShell 内置类的方法吗?如果是，那么如何?任何代码示例都很棒.

Can I overload the PowerShell inbuilt class's methods? If yes then how? Any code sample would be great.

本质上，我试图重载哈希表字典 PowerShell 对象的 Equals 方法以进行适当的比较.

Essentially, I am trying to overload the Equals method of a Hashtable Dictionary PowerShell object to do appropriate comparisons.

我知道您可以在 PowerShell 中重载 cmdlet 或函数，以及采用的最新定义.但我试图重载不是 cmdlet 或函数，而是试图重载现有类的内置方法.我已经检查过这篇文章:PowerShell 中的函数重载

I know that you can overload a cmdlet or a function in PowerShell and whatever is the latest definition that is taken up. But I am trying to overload not a cmdlet or a function, but trying to overload inbuilt method for existing class. I have already checked this post: Function overloading in PowerShell

推荐答案

好吧，您可以通过以下方式从 C# 代码中重载它:

Well, you can overload it from C# code in this manner:

$Source = @"
    class MyHashTable : HashTable
    {
        public override Equals(...) { ... }
    }
"@

Add-Type -TypeDefinition $Source -Language CSharp 

$x = New-Object MyHashTable ...
