Question

我有以下类，但是我需要声明一个字符串数组而不是[String]成员变量。语法是什么？

class SomeClass{
  [String] $patterns;

  SomeClass(){
    $this.patterns = "Maintenance Code","Page \d+ of";
  }

  [Bool]SomeMethod([string]$txt){}
}

Answer 1

因为PetSerAl说[System.String []]但是[String []]就好了。

在帮助about_arrays中也提到过。

To create a strongly typed array, that is, an array that can contain only
    values of a particular type, cast the variable as an array type, such 
    as string[], long[], or int32[]. To cast an array, precede the variable
    name with an array type enclosed in brackets. For example, to create a
    32-bit integer array named $ia containing four integers (1500, 2230, 3350,
    and 4000), type:

        [int32[]]$ia = 1500,2230,3350,4000
