Powershell 2.0运行时异常;无法加载文件或程序集 [英] Powershell 2.0 Runtime exception; could not load file or assembly

问题描述

我正在努力纠正的场景是在C＃编译时找到dll，而在执行c＃代码时找不到的场景。这是Powershell 2.0。我们的政策是不要使用GAC。 Powershell函数中的c＃代码类似于：

  function functionDef 
 {
 [System。 Reflection.Assembly] :: LoadFrom（c：\myDir\func1.dll）
 [System.Reflection.Assembly] :: LoadFrom（c：\myDir\func2.dll）
 
 $ ref = @（c：\myDir\func1.dll，c：\myDir\func2.dll）
 
 $ cCode = @ 
 using System; 
 using func1; 
 using func2; 
 
 namespace serializedDef 
 {
 public class defSerialization 
 {
 
 public defSerialization（）{} 
 
<＃
方法和属性定义不包括
＃> 
 
 public double setSpec {
 set {computeDef（value）} 
 get {return spefDef} 
} 
 
 private double computeDef（double value）
 {
<＃调用DLLS中加载的方法
＃> 
} 
} 
} 
@ 
 add-type -ReferencedAssemblies $ ref -TypeDefinition $ cCode -passthru  - 语言CSharpVersion3 | out-null 
} 
  

调用这个函数时，c＃代码被编译出来错误。

我将两个引用的DLLS的路径添加到$ env：path值。在另一个位置安装了第三方DLL路径DLL;该路径也被添加到$ env：path。两个路径的权限对所有用户都是开放的测试目的。

然后我将C＃代码作为新对象实例：

  $ myObject = new-object serializedDef.defSerialization 
  

当我调用函数时：

  $ myObject.setSpec = 35.5 
  / pre> 
 
 
我收到错误：
 异常设置setSpec ：无法加载文件或副本
'func1'，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = f0a7c34216660f47'或其依赖关系，系统找不到指定的文件。 
在行：1 char：11 
 + $ myObject。 <<< setSpec = 35.5 
 + CategogyInfo：InvalidOperation：（:) []，RuntimeException 
 + FullyQualifedErrorId：PropertyAssignmentException 
  
我的理解是，错误可能与一个DLL引用的方法等有关，无法找到。我如何跟踪这一点？
解决方案
我在回答一中引用发布后建立了一个解决方案（如何使PowerShell添加的类型使用添加的类型 ）。它在x87和x64平台上都能很好地工作。谢谢。
 
The scenario that I am trying to rectify is one in which dlls are found when C# is compiled but not found when the c# code is executed. This is Powershell 2.0. Our policy is to not use the GAC. The c# code in a Powershell function is similar to this:
function functionDef
{
  [System.Reflection.Assembly]::LoadFrom("c:\myDir\func1.dll")
  [System.Reflection.Assembly]::LoadFrom("c:\myDir\func2.dll")

  $ref = @("c:\myDir\func1.dll","c:\myDir\func2.dll")

  $cCode = @"
    using System;
    using func1;
    using func2;

    namespace serializedDef
    {
       public class defSerialization
       {

          public defSerialization () {}

   <# 
             method and properyty defs not included
          #>

          public double setSpec {
  set { computeDef(value)}
  get {return spefDef}
          }

   private double computeDef ( double value)
   {
            <# calls to methods in DLLS loaded above
             #>
   }
       }
    }
 "@
 add-type -ReferencedAssemblies $ref -TypeDefinition $cCode -passthru - Language CSharpVersion3 | out-null
}
When this function is invoked, the c# code is compiled with out error.

I add the path to the two referenced DLLS to the $env:path value. There is a 3rd party DLL path DLL installed at another location; that path too is added to the $env:path. The permissions on both paths are wide open to everyone for testing purposes.

I then instance the C# code as a new object:
 $myObject = new-object serializedDef.defSerialization
When I invoke the function:
 $myObject.setSpec = 35.5
I get the error:
Exception setting "setSpec": "Could not load  file or assmbly
'func1', Version=1.0.0.0, Culture=neutral, PublicKeyToken=f0a7c34216660f47' or one of its dependencies. The system cannot find the file specified."
At line:1 char:11
+ $myObject. <<< setSpec = 35.5
  + CategogyInfo          : InvalidOperation: (:) [], RuntimeException
  + FullyQualifedErrorId  : PropertyAssignmentException
My understanding is that the error is likely is related to a method or the like that one of the DLLs is referencing which can not be found. How do I track this down?
解决方案
I modeled a solution after the posting referenced in Answer one (How can I get PowerShell Added-Types to use Added Types). It works perfectly on both x87 and x64 platforms. Thank-you.
