如何在ASP.NET Web应用程序中卸载C ++ DLL? [英] How to unload a C++ DLL in ASP.NET Web Application?

问题描述

我使用DLLImport加载C ++ DLL，但是现在我发现没有直接方法可以卸载DLL.如果是这样，该方法将无法刷新参数，从而导致逻辑错误.

I use DLLImport to load a C++ DLL, but now I find that there is not a direct method to unload the DLL. If so, the method cannot refresh the parameters,leading to a logical error.

推荐答案

您可以使用以下调用来加载/卸载库:

You can use these calls to load/unload libraries:

[DllImport("kernel32.dll")]
protected internal static extern IntPtr LoadLibrary(string dllToLoad);

[DllImport("kernel32.dll")]
protected internal static extern bool FreeLibrary(IntPtr hModule);

也是有用的:

And also useful:

[DllImport("kernel32.dll")]
private static extern IntPtr GetProcAddress(IntPtr hModule, string procedureName);
