c# - PowerShell:枚举名称中的点导致添加类型失败

Question

我在PowerShell中创建了以下枚举。但是，如果枚举名称中有一个点(例如“Name.A”)，则Add-Type将返回错误。我该怎么办？我不想从“Name.A”中删除该点。

$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，并且通过扩展PowerShell和C#。枚举成员名称中不能包含标点符号。

因此，简短的答案是，如果不做一些棘手的事情，您将无法完成这项工作(您必须将name.A更改为name [CharacterCode] A或添加说明，或者其他您真正不应该做的奇怪的事情)
