C#调用C++接口,帮看看C#的参数是否有错

[验证码识别]

	//参数：[in] imagebuf: 图片内存文件数据
	//      [in] size:     imagebuf大小
	//      [out] text:识别结果
	int __cdecl  GetTessTextByBuf(unsigned char *imagebuf,int size, int type, char *text);  

   [DllImport("OCRapi.dll", EntryPoint = "GetTessTextByBuf", CharSet = CharSet.Ansi,
             CallingConvention = CallingConvention.Cdecl)]
        public static extern int GetTessTextByBuf(ref byte[] imagebuf,int size, int type, StringBuilder text);

C#的参数是否与C++的不对应?
