AspriseOCR

其中需要使用的3个dll是AspriseOCR.dll、DevIL.dll、ILU.dll。 需要注意的是这几个.dll是vc写的引用要在程序中用DllImport引用，关键代码： [DllImport("AspriseOCR.dll", EntryPoint = "OCR", CallingConvention = CallingConvention.Cdecl)] public static extern IntPtr OCR(string file, int type); [DllImport("AspriseOCR.dll", EntryPoint = "OCRpart", CallingConvention = CallingConvention.Cdecl)] static extern IntPtr OCRpart(string file, int type, int startX, int startY, int width, int height); [DllImport("AspriseOCR.dll", EntryPoint = "OCRBarCodes", CallingConvention = CallingConvention.Cdecl)] static extern IntPtr OCRBarCodes(string file, int type); [DllImport("AspriseOCR.dll", EntryPoint = "OCRpartBarCodes", CallingConvention = CallingConvention.Cdecl)] static extern IntPtr OCRpartBarCodes(string file, int type, int startX, int startY, int width, int height); 调用代码很简单只有一句： MessageBox.Show(Marshal.PtrToStringAnsi(OCRpart(img_path, -1, startX, startY, width, height))); 其中img_path：为图片路径，startX、startY坐标均为0即可，width、height图片的宽和高。
