PowerShell：枚举名称中的点导致添加类型失败

Question

我在下面的 PowerShell 中创建了枚举。但是，如果我在枚举名称中有一个点（例如 "Name.A"），那么 Add-Type 将 return 出错。我该怎么做？我不想从 "Name.A".

中删除点

$TypeEnum = "
    namespace Types {
        public enum Id { 
            Name.A = 1,
            NameB = 2,
            NameC = 3
        }   
    }"

Add-Type -TypeDefinition $TypeEnum -Language CSharpVersion3

([Types.Id]::'Name.A').value__

这是我得到的错误：

Add-Type : c:\Users\User1\AppData\Local\Temp\ab0z5i1y.0.cs(4) : } expected c:\Users\User1\AppData\Local\Temp\ab0z5i1y.0.cs(3) :

这是 .Net 的限制，以及 PowerShell 和 C# 的扩展。枚举成员名称中不能有标点符号。

因此简短的回答是，如果不做一些骇人听闻的事情就无法完成这项工作（您必须将 name.A 更改为 name[CharacterCode]A 或添加描述，或其他一些你真的不应该做的奇怪的事情）
