在文件夹中的foreach位图 [英] Foreach bitmap in folder

问题描述

所以下面是使用TessNet的OCR工具来扫描该文件夹中的每个位图和处理OCR信息到列表与LT一些code; tessnet2.Word＆GT;结果。但我似乎无法得到的foreach的工作权利。
 我收到以下错误 foreach语句无法在类型System.IO.DirectoryInfo'变量工作，因为System.IO.DirectoryInfo'不包含'的GetEnumerator'一个公共定义

  DirectoryInfo的diBMP =新的DirectoryInfo（C：\\\\ \\\\温度骨形成蛋白）;                            的foreach（BMP位在diBMP）
                            {
                              使用（tessnet2.Tesseract tessocr =新tessnet2.Tesseract（））
                                    {                                        tessocr.Init（@C：\\用户\\马特·泰勒\\文档\\ Visual Studio 2012中\\项目\\ TessNet2 \\ TessNet2 \\ BIN \\调试\\ tessdata，工程，FALSE）;                                        tessocr.GetThresholdedImage（BMP，System.Drawing.Rectangle.Empty）.Save：（C \\\\ \\\\温度+ Guid.NewGuid（）的ToString（）+.BMP）。
                                        Console.WriteLine（普通版）;
                                        清单＆LT; tessnet2.Word＆GT;结果= ocr.DoOCRNormal（BMP，工程）;                                        CheckANDCorrectPDForientation（结果，pdfFiles）;
                                    }
                            }
 

解决方案

它看起来像你想

 的foreach（字符串s在Directory.EnumerateFiles（目录，* .BMP））
{
    使用（BMP位图=新位图（S））
    {
      // code在这里
     }
 }
 

您的错误是因为foreach循环必须具备的东西通过循环，的DirectoryInfo 只会给你有关的目录信息

So below is some code that uses TessNet's OCR tool to scans each bitmap in the folder and processes the OCR information into List<tessnet2.Word> result. But I can't seem to get the foreach to work right. I get the following error foreach statement cannot operate on variables of type 'System.IO.DirectoryInfo' because 'System.IO.DirectoryInfo' does not contain a public definition for 'GetEnumerator'

     DirectoryInfo diBMP = new DirectoryInfo("c:\\temp\\bmps");

                            foreach (Bitmap bmp in diBMP)
                            {                                         
                              using (tessnet2.Tesseract tessocr = new tessnet2.Tesseract())
                                    {                                        

                                        tessocr.Init(@"C:\Users\Matt Taylor\Documents\Visual Studio 2012\Projects\TessNet2\TessNet2\bin\Debug\tessdata", "eng", false);

                                        tessocr.GetThresholdedImage(bmp, System.Drawing.Rectangle.Empty).Save("c:\\temp\\" + Guid.NewGuid().ToString() + ".bmp");


                                        Console.WriteLine("Normal version");
                                        List<tessnet2.Word> result = ocr.DoOCRNormal(bmp, "eng");

                                        CheckANDCorrectPDForientation(result, pdfFiles);                                                                             
                                    }                                    
                            }

解决方案

It looks like you want

foreach(string s in Directory.EnumerateFiles(dir, "*.bmp"))
{
    using(Bitmap bmp = new Bitmap(s))
    {
      //code here
     }
 }

Your error is because a foreach loop must have something to loop through, DirectoryInfo will just give you information about the directory
