Microsoft Flight Simulator插件开发遇System.BadImageFormatException求助

Common Causes & Solutions #

1. Verify Complete x86 Configuration #

• Ensure both project build settings and solution build settings are set to x86. It's easy to change one but overlook the other.
• Confirm you're referencing the x86 version of SimConnect.dll from the SDK's lib\x86 directory. Using the x64 DLL in an x86 project will trigger this error.

2. Correct Platform Target Settings #

• In Visual Studio, go to Project Properties > Build:
  • Set Platform target to x86 (not "Any CPU").
  • Uncheck "Prefer 32-bit" if enabled—this setting can cause conflicts with explicit x86 requirements.

3. Clean Up Conflicting Binaries #

• Run Build > Clean Solution to remove any leftover x64 files from previous builds.
• Rebuild the project to ensure all binaries are compiled for x86.

4. Check SimConnect Version Compatibility #

• Ensure your SimConnect SDK version matches the version of Microsoft Flight Simulator you're running. Mismatched versions can lead to format errors.

5. Fix the Window Handle Issue in Code #

Your current code uses IntPtr(0) as the window handle, which is invalid for SimConnect's message-based communication. Console apps don't have a proper message loop, so switch to using an event handle instead:

using Microsoft.FlightSimulator.SimConnect;
using System;
using System.Runtime.InteropServices;
using System.Threading;

internal class Program
{
    SimConnect? simConnect;
    private EventWaitHandle? simConnectEvent;

    void Run()
    {
        try
        {
            simConnectEvent = new EventWaitHandle(false, EventResetMode.AutoReset);
            // Use event handle instead of window handle
            simConnect = new SimConnect("Managed Data Request", IntPtr.Zero, 0, simConnectEvent.SafeWaitHandle.DangerousGetHandle(), 0);

            // Subscribe to connection success event
            simConnect.OnRecvOpen += SimConnect_OnRecvOpen;

            // Keep the app running to process events
            while (true)
            {
                simConnectEvent.WaitOne();
                simConnect.ReceiveMessage();
            }
        }
        catch (COMException ex)
        {
            Console.WriteLine($"Connection error: {ex.Message}");
        }
        finally
        {
            simConnect?.Dispose();
            simConnectEvent?.Dispose();
        }
    }

    private void SimConnect_OnRecvOpen(SimConnect sender, SIMCONNECT_RECV_OPEN data)
    {
        Console.WriteLine($"Connected to MSFS! Simulator version: {data.szApplicationName}");
    }

    static void Main(string[] args)
    {
        new Program().Run();
    }
}
