用于保存大量数字的 PowerShell 变量类型

Question

我需要在 PowerShell FOREACH 循环中处理大量数字。我收到以下异常:

Cannot convert value "60000000000" to type "System.Int32"

[long]$LargeNumber = 60000000000
 foreach ($i in 1..$LargeNumber) {
  $i 
 }

我做错了什么？

Answer 1

似乎 powershell 的范围运算符 (..) 存在限制，将输入参数限制为 Int32。我找不到官方文档，但是 according to this page :

2 Restrictions and a Caveat There are only two basic restrictions on range use. The first restriction is that the numbers in the range must be between -2,147,483,648 and 2,147,483,647, inclusive; this limit is because PowerShell's range operator changes the values into 32-bit .NET integers, which can only take on these values. The second limit is that an individual range can contain no more than 50,001 items.
