J'essaie d'utiliser plusieurs fonctions de kernal32.dll. Cependant, lorsque ma demande essaie d'appeler la première fonction, il jette un EntryPointNotFoundException Unable to find an entry point named 'SetDllDirectory' in DLL 'kernel32.dll'.
C# EntryPointNotFoundException Impossible de trouver un point d'entrée nommé 'SetDllDirectory' dans la DLL 'kernel32.dll'
public class MyClass
{
/// <summary>
/// Use to interface to kernel32.dll for dynamic loading of similar DLLs.
/// </summary>
internal static class UnsafeNativeMethods
{
[DllImport("kernel32.dll", CharSet = CharSet.Ansi, ExactSpelling = true, SetLastError = true)]
internal static extern IntPtr LoadLibrary(string lpFileName);
[DllImport("kernel32.dll", CharSet = CharSet.Ansi, ExactSpelling = true, SetLastError = true)]
internal static extern bool SetDllDirectory(string lpPathName);
[DllImport("kernel32.dll", CharSet = CharSet.Ansi, ExactSpelling = true, SetLastError = true)]
internal static extern IntPtr GetProcAddress(IntPtr hModule, string procName);
}
private void MyFunc()
{
if (UnsafeNativeMethods.SetDllDirectory(_location) == false) // <-- Exception thrown here.
{
throw new FileNotFoundException(_location);
}
/* Some code. */
_dllHandle = UnsafeNativeMethods.LoadLibrary(_fullPath);
/* Some more code. */
_fptr = UnsafeNativeMethods.GetProcAddress(_dllHandle, _procName);
/* Yet even more code. */
}
}
Toute réflexion sur ce que je fais mal et comment je peux le faire fonctionner serait grandement apprécié. Merci.
