在Windows PowerShell 5.1中调用NDepend API遇CLS大小写兼容错误

我希望在Windows PowerShell 5.1脚本中调用NDepend API，但Windows PowerShell无法处理仅大小写不同的属性，导致操作受阻。

可运行的基础PowerShell代码 #

using namespace NDepend

Set-StrictMode -Version Latest

$AssList = "NDepend.API", "NDepend.Core", "NDepend.Platform.DotNet", "NDepend.Analysis", "NDepend.Platform.DotNet.NetFx", "NDepend.UI.NetFx"

$AssList.ForEach{
    $AssPfad = Join-Path -Path "D:\Program Files\NDepend\Lib" -ChildPath "$_.dll"
    Add-Type -Path $AssPfad
}

$ndprojPath = "D:\Test1234.ndproj"
# 为了清晰仍保留NDepend命名空间（虽然没必要）
$ndprojPathAbsolute = [NDepend.Path.PathHelpers]::ToAbsoluteFilePath($ndprojPath)
$ndProvider = [NDepend.NDependServicesProvider]::new()
$ndManager = $ndProvider.ProjectManager
$project = $ndManager.LoadProject($ndprojPathAbsolute)
$outputDirPath = Join-Path -Path $PSScriptRoot -ChildPath "OutputDir"
$project.Properties.OutputDir = [NDepend.Path.PathHelpers]::ToDirectoryPath($outputDirPath)
$analysisResult = [NDepend.Analysis.ExtensionMethodsProjectAnalysis]::RunAnalysisAndBuildReport($project)
$ndCodebase = $analysisResult.CodeBase

输出$ndCodebase时触发的错误 #

format-default : # The field or property "F18r" for type "a.QHkY" differs only in letter casing from the field or property "f18R". The type must be Common Language Specification (CLS) compliant

脚本中可正常运行的部分 #

以下代码能正常执行并输出分析结果：

$Issues = [Analysis.ExtensionMethodsProjectAnalysis]::ComputeIssues($analysisResult)
$ndIssuesSet = $Issues 
$ndIssuesSet.AllRules

目前我不确定如何规避上述错误。

PS：该问题仅能通过构建许可证复现。

更新1：通过反射定位引发错误的属性 #

感谢mklement0的评论与建议，我已通过反射找到引发错误的属性：

$Ass = [AppDomain]::CurrentDomain.GetAssemblies().Where{$_.GetName().Name -eq "NDepend.Core"}[0]
$t = $ass.gettype("a.QHkY", $True)
# 仅用于信息查看
$t.GetProperties().Where{$_.Name -match "f18r"}

# 无法通过忽略大小写的反射获取该属性？
$PropInfo1 =  $ass.gettype("a.QHkY", $True).GetProperty("f18r", [System.Reflection.BindingFlags]::IgnoreCase) 
# 可以获取该属性
$PropInfo2 =  $ass.gettype("a.QHkY", $True).GetProperty("F18r") 
# 由于$PropInfo1为null，无法获取值
$PropInfo1.GetValue($analysisResult.CodeBase)
# 可以获取值
$PropInfo2.GetValue($analysisResult.CodeBase)

更新2：直接获取CodeBase属性值仍报错 #

当我尝试获取CodeBase属性的值时，还是会遇到相同的format-default错误：

# 获取CodeBase属性的值
$PropInfo = $ass.gettype("a.vHLF", $True).GetProperty("CodeBase")
$Value = $PropInfo.GetValue($ndCodebase)
$Value

$Value确实包含CodeBase对象的值，但似乎是PowerShell格式化程序触发了错误。

更新3：嵌入C#的解决方案（但过于繁琐） #

正如mklement0所建议，问题的核心是需要将对象“重新封装”为自定义类型并保留所需属性。我通过在PowerShell脚本中嵌入C#代码实现了该方案，但这种方式太过繁琐：

using namespace NDepend

Set-StrictMode -Version Latest

$AssList = "NDepend.API", "NDepend.Core", "NDepend.Platform.DotNet", "NDepend.Analysis", "NDepend.Platform.DotNet.NetFx", "NDepend.UI.NetFx"

$AssList.ForEach{
    $AssPfad = Join-Path -Path "D:\Program Files\NDepend\Lib" -ChildPath "$_.dll"
    Add-Type -Path $AssPfad
}

$ndprojPath = "D:\Test.ndproj"
# 为了清晰仍保留NDepend命名空间（虽然没必要）
$ndprojPathAbsolute = [Path.PathHelpers]::ToAbsoluteFilePath($ndprojPath)
$ndProvider = [NDepend.NDependServicesProvider]::new()
$ndManager = $ndProvider.ProjectManager
$project = $ndManager.LoadProject($ndprojPathAbsolute)
$analysisResult = [NDepend.Analysis.ExtensionMethodsProjectAnalysis]::RunAnalysis($project)

# 在C#中进行反射操作，避免直接在PowerShell中处理CodeBase对象
$CSCode = @"
using NDepend.Analysis;
using NDepend.Issue;
using NDepend.CodeModel;

using System;

using System.Linq;

public class CodeBaseInfo
{
    public ICodeBase CodeBase { get; set; }
    public int NbLinesOfCode { get; set; }

    public CodeBaseInfo(IAnalysisResult analysisResult)
    {
        this.CodeBase = analysisResult.CodeBase;
        var ass = AppDomain.CurrentDomain.GetAssemblies().Where(a=>a.GetName().Name == "NDepend.Core").First();
        var propInfo = ass.GetType("a.vHLF").GetProperty("CodeBase");
        var propValue = propInfo.GetValue(analysisResult); 
        propInfo = ass.GetType("a.QHkY").GetProperty("NbLinesOfCode");
        this.NbLinesOfCode = Convert.ToInt32(propInfo.GetValue(propValue));
    }

    // 会触发格式错误——仅作演示用
    public ICodeBase GetCodeBase()
    {
        return this.CodeBase;
    }

    public ICodeBaseView GetApplication() {
        return this.CodeBase.Application;
    }

    public int GetNbLinesOfCode() {
        return this.NbLinesOfCode;
    }
