PowerTip of the Day-Creating Your Own Types

原文：

Did you know that you can compile any .NET source code on the fly and use this to create your own types? Here is an example illustrating how to create a new type from c# code that has both static and dynamic methods:

$source = @'
public class Calculator
{
    public static int Add(int a, int b)
    {
        return (a + b);
    }

public int Multiply(int a, int b)
    {
        return (a * b);
    }
}
'@
Add-Type -TypeDefinition $source
[Calculator]
[Calculator]::Add(5,10)
$myCalculator = New-Object Calculator
$myCalculator.Multiply(3,12)

你知道你可以编译任何即时.net源代码并且作为你的自定义类型使用它们吗？以下是一个示例阐述如何通过c#来创建一个拥有静态方法和实例方法的类型：

$source = @'
public class Calculator
{
    public static int Add(int a, int b)
    {
        return (a + b);
    }

public int Multiply(int a, int b)
    {
        return (a * b);
    }
}
'@
Add-Type -TypeDefinition $source
[Calculator]
[Calculator]::Add(5,10)
$myCalculator = New-Object Calculator
$myCalculator.Multiply(3,12)

 

 

笔记：

直接在ps代码中创建一个类。

复习.net类的静态方法和实例方法的调用方法。

个人倾向于用先把逻辑编译成dll然后在ps里调用。
