如何使用LoadLibrary或任何其他方法加载dll及其依赖项

本文关键字:dll 依赖 加载 方法 LoadLibrary 何使用 任何 其他 | 更新日期: 2023-09-27 17:57:43

我正在尝试加载一个库,用于interop,该库具有一些dll依赖项,所有名称我都知道,但位置是动态的。我可以在"main"dll上调用LoadLibrary,如果其他的都在工作目录上,它就可以正常工作,但事实并非如此。我试着对每个人调用LoadLibrary,但没用。

有什么想法吗?有LoadLibrary的替代方案吗?

.NET 4.5 sivellight5项目,与fortran互操作。

        var interopPath = CreateDllFromResource(dllName);
        var d1=CreateDllFromResource("libgcc_s_dw2-1.dll");
        var d2 = CreateDllFromResource("libgfortran-3.dll");
        var d3 = CreateDllFromResource("libquadmath-0.dll");

        pDll = NativeMethods.LoadLibrary(interopPath);
        NativeMethods.LoadLibrary(d1);
        NativeMethods.LoadLibrary(d2);
        NativeMethods.LoadLibrary(d3);
        //oh dear, error handling here
        if (pDll == IntPtr.Zero)
        {
            throw new Exception("Dll Pointer is null! // Path: " + interopPath + "// Error: " + WSAGetLastError());
        }
        IntPtr pAddressOfFunctionToCall = NativeMethods.GetProcAddress(pDll, "ingammaextern_");
        if (pAddressOfFunctionToCall == IntPtr.Zero)
        {
            throw new Exception("Function Pointer is null!");
        }

如何使用LoadLibrary或任何其他方法加载dll及其依赖项

必须调用LoadLibrary并使用SetDllDirectory才能工作,使用DllImport而不是LoadLibrary不起作用。

    [UnmanagedFunctionPointer(CallingConvention.Cdecl)]
        private delegate void ingammaextern_(StringBuilder resulfilesparam);

{
   var dllName = "SubsCalculator1.dll";
            var interopPath = CreateDllFromResource(dllName);
            var d1 = CreateDllFromResource("libgcc_s_dw2-1.dll");
            var d2 = CreateDllFromResource("libgfortran-3.dll");
            var d3 = CreateDllFromResource("libquadmath-0.dll");
            string folderPath ="C:'folder'
            SetDllDirectory(folderPath);
            pDll = NativeMethods.LoadLibrary(interopPath);
}
