如何判断一个DLL是否可以访问？ [英] How can I tell if a DLL is ComVisible?

问题描述

我有一个可能会将ComVisible属性设置为true或不可能的DLL。我不知道它是如何构建的，还是什么属性？我知道的是，它是一个.Net DLL。简单的说，如何知道Com是否可见？

I have a DLL that may or may not have its ComVisible attribute set to true. I'm not sure how it was built, or with what attributes? All I know is that it's a .Net DLL. Simply put, how can I tell if it is Com Visible?

如果这是重复的话，抱歉。所有关于此返回结果的搜索结果显示了如何使一个DLL ComVisible。我知道如何做到这一点。

Sorry if this is a duplicate. All of my searches about this return results that show how to make a DLL ComVisible. I know how to do that.

推荐答案

你可以查看 ComVisibleAttribute ：

private static bool IsComVisible(string assemblyPath)
{
  var assembly = Assembly.LoadFile(assemblyPath);

  var attributes = assembly.GetCustomAttributes(typeof(ComVisibleAttribute), false);

  if (attributes.Length > 0)
  {
    return ((ComVisibleAttribute)attributes[0]).Value;
  }

  return false;
}
