[英]Is there a way to call an unmanaged (not COM) dll from C# application?
Is there a way to use (reference) a DLL written in an unmanaged C++ (not a COM library) in my C# application? 有没有办法在我的C#应用程序中使用(引用)用非托管C ++(不是COM库)编写的DLL?
When I try to reference it from within Visual Studio, I get 'not a COM object' error message. 当我尝试从Visual Studio中引用它时,出现“不是COM对象”错误消息。
Maybe there is some kind of translator\\router that would COMify my DLL reference? 也许有某种translator \\ router可以修改我的DLL参考? I have no clue how COM and COM interop work, since I started programming when this was already unnecessary for me.
我不知道COM和COM互操作的工作原理,因为我开始编程时对我来说已经不需要了。
Thank you. 谢谢。
You need to use the DllImport attribute. 您需要使用DllImport属性。 Here's an example for the Win32 PostMessage function:
这是Win32 PostMessage函数的示例:
[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
internal static extern bool PostMessage(IntPtr handle, int message, IntPtr wparam, IntPtr lparam);
See " Consuming unmanaged DLL functions " topic on MSDN: 请参阅MSDN上的“使用非托管DLL函数 ”主题:
http://msdn.microsoft.com/en-us/library/26thfadc.aspx http://msdn.microsoft.com/zh-CN/library/26thfadc.aspx
There is no need to add any COM proxy, .NET can consume DLLs directly using the [DllImport] attribute. 无需添加任何COM代理,.NET可以使用[DllImport]属性直接使用DLL。 You also have full control over the marshalling between .NET and the unmanaged DLL by specifying additional attributes.
您还可以通过指定其他属性来完全控制.NET和非托管DLL之间的编组。
Joe already answered this, so I'm going to tack this on - to save yourself some time and not having to dig up and mangle function signatures, P/Invoke has a pretty complete library of Win32 signatures, in the form of both a wiki AND a Visual Studio plugin! 乔已经回答了这个问题,所以我要继续解决这个问题-为节省时间,而不必深入研究和破坏函数签名,P / Invoke具有相当完整的Win32签名库,以Wiki的形式提供和一个Visual Studio插件!
Check it out at P/Invoke 在P / Invoke签出
