自定义程序集被添加到PowerShell程序集中，但仍然无法编译

本文关键字：程序集 编译 集中 添加 PowerShell 程序 自定义 | 更新日期: 2023-09-27 17:50:12

我试图在PowerShell中使用自定义。net程序集运行c#代码，但无法使其工作。

下面是我的代码: 
# Adding custom assemblies to the PowerShell assemblies
Add-Type -Verbose -Path "C:'MyCustomAssembly.dll"
# Adding reference of standard .NET assemblies 
$Refs = @("C:'Program Files (x86)'Reference Assemblies'Microsoft'Framework'.NETFramework'v4.5'System.Xml.dll",
"C:'Program Files (x86)'Reference Assemblies'Microsoft'Framework'.NETFramework'v4.5'System.Data.Entity.dll",
"C:'Program Files (x86)'Reference Assemblies'Microsoft'Framework'.NETFramework'v4.5'System.Runtime.Serialization.dll")
$Source = @"
using System;
using System.IO;
using System.Net;
using System.Runtime.Serialization;
using MyCustomAssembly;
namespace CSharpCode
{
    public class WebClient
    {
        public void ConsumePostMethod()
        { ... }
    }
}
"@
Add-Type -ReferencedAssemblies $Refs -TypeDefinition $Source -Language CSharp -PassThru
[CSharpCode.WebClient]::ConsumePostMethod()

这是我得到的错误:

Add-Type : c:'Users'MyUser'AppData'Local'Temp'znllnhvt.0.cs(5) : The type or namespace name 'MyCustomAssembly' could not be found (are you missing a using directive 
or an assembly reference?)

c:'Users'MyUser'AppData'Local'Temp'znllnhvt.0.cs(5) : >>> using MyCustomAssembly;

奇怪的是，如果我在下面运行这个命令，它显示MyCustomAssembly.dll在会话中加载。有人能帮忙吗?!

[System.AppDomain]::CurrentDomain.GetAssemblies() | Where {$_.Location} | ForEach {Split-Path -Leaf $_.Location} | Sort 

Accessibility.dll
MyCustomAssembly.dll
Microsoft.Build.Framework.dll
Microsoft.CSharp.dll
...

自定义程序集被添加到PowerShell程序集中，但仍然无法编译

Add-Type不使用任何当前加载的程序集作为隐式引用。因此，如果您想在Add-Type源代码中使用自定义程序集中的任何类型，那么您应该显式地将该程序集添加到-ReferencedAssemblies参数中。
