确定装配类型的好方法?

根据 a search of the reference source ,的 PEFileKinds 枚举仅用于 AssemblyBuilder ModuleBuilder (以及它们的非公共助手类型)。此枚举和类位于 System.Reflection.Emit namespace

然而, the official System.Reflection.Metadata NuGet package 在程序集中显示程序集的PE头的相关值 System.Reflection.PortableExecutable namespace 培林 价值观。下面是C#中的一个例子:

using (var stream = File.OpenRead(filenameAndExtension))
{
    using (var peFile = new PEReader(stream))
    {
        var headers = peFile.PEHeaders;
        Console.WriteLine($"Reading {filenameAndExtension} with System.Reflection.Metadata");
        Console.WriteLine($"  IsDll: {headers.IsDll}");
        Console.WriteLine($"  IsExe: {headers.IsExe}");
        Console.WriteLine($"  IsConsoleApplication: {headers.IsConsoleApplication}");

        PEFileKinds reverseEngineeredKind;

        // NOTE: the header values cause IsConsoleApplication to return
        //       true for DLLs, so we need to check IsDll first
        if (headers.IsDll)
        {
            reverseEngineeredKind = PEFileKinds.Dll;
        }
        else if (headers.IsConsoleApplication)
        {
            reverseEngineeredKind = PEFileKinds.ConsoleApplication;
        }
        else
        {
            reverseEngineeredKind = PEFileKinds.WindowApplication;
        }
        Console.WriteLine($"  Reverse-engineered kind: {reverseEngineeredKind}");
    }
}

您也可以通过第三方库获取这些信息,如 Mono.Cecil 或者,正如莱克斯李提到的, PeNet
