自从这个问题在四年前被提出并回答以来，PowerShell一直在不断发展。@KeithHill的简洁答案不幸地不再起作用。我做了一点挖掘，发现必需的类只是暴露得少了一点。从好的方面来说，类型加速器的列表现在可能只显示这一行代码...

[psobject].assembly.gettype("System.Management.Automation.TypeAccelerators")::Get

.归因于Jaykul在这个Connect post.
以下是部分输出：

从PowerShell Community Extensions（PSCX）版本3.1.0开始，您现在可以使用类型加速器来列出所有类型加速器，只需调用以下内容：

[accelerators]::get

最后的方法是按照Oisin在excellent blog post中所演示的来做：

PS> $acceleratorsType = [type]::gettype("System.Management.Automation.TypeAccelerators")
PS> $acceleratorsType

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
False    False    TypeAccelerators                         System.Object

PS> $acceleratorsType::Add("accelerators", $acceleratorsType)
PS> [accelerators]::Get

Key                                                         Value
---                                                         -----
int                                                         System.Int32
...

请注意，你必须将新的'accelerators'加速器添加到字典中，因为TypeAccelerators类型不是公共的。你可以用.NET Reflector和大量的空闲时间做很多令人惊讶的事情。

请参阅this blog post中标题为 * 类型名称别名 * 的部分。我相信这是别名的完整列表。

**PowerShell Type Alias   Corresponding .NET Type**
[int]                   System.Int32

[type]                  System.Type
[type[]]                System.Type[]

@Noldorin有一个很好的列表，列出了一些类型加速器。
PowerShell还允许您使用类型文本来强制转换对象、调用静态方法、访问静态属性、反射以及您可能对System.Type对象的示例执行的任何其他操作。
为了使用类型字面量，您只需将类（或结构或枚举）的全名（命名空间和类名）（用句点分隔命名空间和类名）括在括号中，如：

[System.Net.NetworkInformation.IPStatus]

PowerShell还将在尝试解析名称时提供前导“System.”，因此如果您正在使用System* 命名空间中的内容，则不需要显式使用该名称。

[Net.NetworkInformation.IPStatus]

Oisin Grehan (a PowerShell MVP) also has a blog post about creating your own type accelerators。
