我在C＃中创建一个PowerShell Cmdlet来读取JSON文件中的字段并输出一些对象。对象是一个简单的POCO类型：
public class FieldDefinition
{
public FieldDefinition(string name, TypeCode code)
{
Name = name;
Code = code;
}
public string Name { get; }
public TypeCode Code { get; }
}
编写输出时，条目显示为：
PS ~Debug> Get-Field
Name : Session
Code : Int64
Name : Instance
Code : String
理想情况下，我希望默认演示文稿为表格：
PS ~Debug> Get-Field | Format-Table
Name Code
---- ----
Session Int64
Instance String
当我调用Get-Process之类的命令时，我总是会看到表格格式。如何让命令将其输出显示为表格？

每次命令输出数据表时，输出实际上（无形地）通过管道输出到Out-Default命令。这反过来管道数据（无形） 到defualt目的地，默认情况下是“out-host”，即终端。
out-host使用以下文件中包含的格式化信息将数据格式化为表格形式：
C：\ Windows \ systems32 \ windowspowershell \ V1.0 \ DotNetTypes.format.ps1xml （注意：不要编辑这个文件，因为它是经过数字签名的。所以如果你进行最微小的改动，powershell将停止工作）
它通过查找xml文件来查找匹配对象的条目（可以使用get-member找到）
所有out- *命令也使用相同的xml文件（尽管write-host是一个例外，稍后会介绍）。
但是，命令可能会输出一个在xml文件中没有预定义视图的表。在这种情况下，out- *命令 查找辅助xml文件以获取格式指导：
C：\ Windows \ systems32 \ windowspowershell \ V1.0 \ Types.ps1xml

您需要添加一个format.ps1xml文件来设置输出的布局。

我以前为脚本模块做过这个。
可以在本地计算机上找到示例 C：\ Windows \ System32下\ WindowsPowershell \ V1.0
上述位置有一些* .ps1xml文件。

尝试使用此方法而不是使用格式表。您将一个成员集添加到您的对象。
