我希望我的 C# 应用程序有条件地运行 native 方法，有条件地选择运行 dll 的 x86 或 x64 版本。每当我尝试加载 32 位 dll 时，我都会收到以下错误:
Unhandled Exception: System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
at <exeName>.MiniDumpMethods.MiniDumpWriteDumpX86(IntPtr hProcess, UInt32 processId, SafeHandle hFile, MINIDUMP_TYPE dumpType, IntPtr expParam, IntPtr userStreamParam, IntPtr callbackParam)
背景上下文:我希望我的二进制文件获取给定进程的内存转储。根据进行内存转储的进程是 32 位还是 64 位，它将选择从 dbghelp.dll 的 x86 或 x64 版本运行 MiniDumpwriteDump 方法。
我目前正在做以下事情:
[SuppressUnmanagedCodeSecurity]
internal static class MiniDumpMethods
{
[DllImport("dbghelp.dll",
EntryPoint = "MiniDumpWriteDump",
CallingConvention = CallingConvention.StdCall,
CharSet = CharSet.Unicode,
ExactSpelling = true,
SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool MiniDumpWriteDump(
IntPtr hProcess,
uint processId,
SafeHandle hFile,
MINIDUMP_TYPE dumpType,
IntPtr expParam,
IntPtr userStreamParam,
IntPtr callbackParam);
[DllImport("dbghelpx86.dll",
EntryPoint = "MiniDumpWriteDump",
CallingConvention = CallingConvention.StdCall,
CharSet = CharSet.Unicode,
ExactSpelling = true,
SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool MiniDumpWriteDumpX86(
IntPtr hProcess,
uint processId,
SafeHandle hFile,
MINIDUMP_TYPE dumpType,
IntPtr expParam,
IntPtr userStreamParam,
IntPtr callbackParam);
}
知道如何有条件地加载 dll 的 x86 或 x64 版本吗？
(注:dbghelpx86.dll是我重命名的x86版本的dbghelp.dll)
谢谢
