Question

这是我的应用程序代码。简单一点。我是C＃的新手。我尝试了其他完美的例子。但是例外情况“尝试加载格式不正确的程序”。我不知道为什么。请告诉我。有没有一种方法，Core.dll不允许动态加载和反射调用。

           Assembly asm = null;
            try
            {
                // Excepition in this line
                 asm = Assembly.LoadFrom(@"C:\myproj\Core.dll");
            }
            catch (Exception e)
            {
                Console.WriteLine(e.GetBaseException());
                Console.WriteLine(e.Message);

            }

        MethodInfo staticMethodInfo = t.GetMethod("Create");
        if (staticMethodInfo == null)
        {

        }
        List<Assembly> assemblies = new List<Assembly>();
        staticMethodInfo.Invoke(null, new object[] { typeof(string), typeof(JObject), assemblies });

我收到以下异常： -

错误消息确切地告诉您错误：

警告：不会在LoadFrom上下文中探测本机映像。仅在默认加载上下文中探测本机映像，例如Assembly.Load（）。

您的程序集不是.NET IL 程序集，并且无法在您尝试加载它时加载。您需要改为使用Assembly.Load()。

为什么C＃反射抛出这个BadImageFormatException
