Question

假设我在一个powershell脚本中用C＃定义了以下类：

Add-Type -TypeDefinition @"
public class InnerClass {
    int a, b;
    public int A { get { return a; } set { a = value; } }
    public int B { get { return b; } set { b = value; } }
}
public class SomeClass {
    string name;
    public string Name { get { return name; } set { name= value; } }
    InnerClass numbers;
    public InnerClass Numbers { get { return numbers; } set { numbers = value; } }
}
"@

我可以像这样实例化InnerClass的实例：

New-Object InnerClass -Property  @{
    'A' = 1;
    'B' = 2;
}

但是，如果我要实例化SomeClass并以类似方式设置InnerClass的属性，则会失败。

New-Object SomeClass -Property @{
    'Name' = "Justin Dearing";
    Numbers = @{
        'A' = 1;
        'B' = 2;
    };
} ;

New-Object : The value supplied is not valid, or the property is read-only. Cha
nge the value, and then try again.

   jectCommand



Name    : Justin Dearing
Numbers :

无论如何设置SomeClass，包括一个New-Object语句中Numbers的属性？

Answer 1

你不能直接但你可以使用

内联构造内部类

New-Object SomeClass -Property @{
'Name' = "Justin Dearing";
'Numbers' = New-Object InnerClass -Property  @{
  'A' = 1;
  'B' = 2;
 }  
};

你应该这样做我相信：

New-Object SomeClass -Property @{
     'Name' = "Justin Dearing";
     Numbers = New-Object InnerClass -Property  @{
                'A' = 1;
                'B' = 2;
            };
} ;

使用New-Object -Property设置嵌套类的属性
