BadImageFormatException 0x800700C1

问题描述

大家好.
我使用Visual Studio 2008 Express C#构建项目.基本上我试图使用以下代码在Windows 7 x64上通过directsound捕获音频，但这给了我错误:
BadImageFormatException不是有效的Win32应用程序. (来自HRESULT的异常:0x800700C1)

谁能看到我的代码在我的哪里出了问题，或者我该如何解决这个问题?
我已将其设置为使用x86而不是x64或AnyCpu进行编译，但也尝试过使用这些方法

Hi Everyone.
Im building an project using Visual studio 2008 express c#. Basically im trying to catch audio via directsound on Window 7 x64 using the below code but it is giving me the error:
BadImageFormatException is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)

Can anyone see where ive went wrong with my code or how i could fix this issue?
I''ve set it to compile using x86 rather than x64 or AnyCpu but have tried those aswell

            _notify.SetNotificationPositions(new BufferPositionNotify[] { bpn1, bpn2 });
        }

        private void checkBox1_CheckedChanged(object sender, EventArgs e)
        {
            if (this.checkBox1.Checked == true)
            {

                    {
                        _resetEvent.WaitOne();
                        _dwCapBuffer.Read(offset, typeof(short), LockFlag.None, _dwOutputBufferSize);
                        offset = (offset + _dwOutputBufferSize) % _dwCaptureBufferSize;
                    }
                    _dwCapBuffer.Stop();
                });
                _dwCaptureThread.Start();
            }
        }
    }
}

哦，使用DirectSound而不是Xaudio的原因是XP系统的向后兼容性.

Oh and the reason for using DirectSound instead of Xaudio is for backward compatability for XP systems.
