BadImageFormatException 0x800700C1 [英] 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

                        _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.

推荐答案

您是这么说的，但是您是否在其中设置了"Target Platform"属性属性页还是ide的主要形式上的组合框?

You said so, but did you set the "Target Platform" property in the property page or the Combobox on the mainform of the ide?
