程序集无法加载,没有融合日志错误

我有一个非常小的控制台应用程序,它只是试图从引用的程序集中打印出枚举的值。让我们调用程序集“VendorAssembly.DDK.dll”,并说它定义“Vendor.Namespace”。这是我的匿名测试代码。 IntervalType只是一个枚举。

using Vendor.Namespace;

class Program
{
    static void Main(string[] args)
    {
        try
        {
            IntervalType h = IntervalType.Hours;

            Console.WriteLine($"{h}");
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            throw;
        }
    }
}

它汇编得很好。

但是当我尝试运行它时,会立即发生异常(在实际输入Main()方法之前),它说: System.IO.FileNotFoundException was unhandled Message: An unhandled exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll Additional information: Could not load file or assembly 'VendorAssembly.DDK.dll' or one of its dependencies. The specified module could not be found.

即使我尝试多次运行此应用程序,fuslogvw.exe也不会列出任何绑定错误。将fuslogvw.exe设置为“将所有绑定到磁盘”并启用自定义日志路径后,搜索自定义融合日志文件夹会显示一个绑定事件,这显然是成功的吗?

VendorAssembly.DDK.DLL是一个托管包装器,它调用非托管C ++代码。查看Visual Studio Assembly Explorer中的VendorAssembly.DDK.dll表示它引用了mscorlibSystemSystem.Configuration.InstallSystem.DataSystem.Xml和{{ 1}}。我已将所有列出的.NET程序集添加为Console应用程序的引用。

我的控制台应用程序面向x64平台和.NET 4.5.1,它与VendorAssembly.DDK.dll上的元数据完全匹配。

如何正确加载此程序集需要做什么?

为什么fuslogvw没有显示出错的地方?

1 个答案:

答案 0 :(得分:1)

程序集加载失败是由{em>非托管(C ++ DLL)VendorAssembly.DDK.dll依赖项引起的,这些依赖项在Visual Studio的Assembly Explorer中不可见,在Fusion日志中未提及由fuslogvw.exe显示,并且未在.NET反射异常堆栈跟踪中详细说明。

我使用Dependency Walker来识别和分析非托管依赖项。

另一个用于识别非托管依赖项缺失的有用工具是Sysinternals Process Monitor (Procmon),它可以在进程无法加载时列出运行时缺少的非托管依赖项的名称。
