StreamReader C＃

Question

使用C＃中的streamReader函数读取文本文件（其中包含要导出到数据库的文件的位置）时，如何向将在命令提示符中显示的代码添加确认消息窗口（控制台应用程序），以便我知道文件被读取并导出？

public class Script 
{ 
    public static void Main(string[] args) 
    { 
     // Prepare the type that will handle all of the exporting needs 
     FileExporter exporter = new FileExporter(); 

     try 
     { 
      //create an instance of StreamReader to read from a file. 
      //The using statemen also closes the StreamReader. 
      using (StreamReader sr = new StreamReader("ScriptFile.txt")) 
      { 
       string filePath; 
       //read and display lines from the file until the end of 
       //the file is reached. 
       while ((filePath = sr.ReadLine()) != null) 
       { 
        // Throw error if file does not exists to terminate the process. 
        if (!File.Exists(filePath)) 
        { 
         string msg = string.Format("File not found at {0}.", filePath); 
         throw new FileNotFoundException(msg); 
        } 

        // Set the name of the export to be the name of the file. 
        string exportName = new FileInfo(filePath).Name; 

        // Export image as an SHP file if the extension matches. 
        if (filePath.Contains(".shp")) 
        { 
         exporter.processSHP(filePath, exportName, ""); 
         //need confirmation that exporter.processSHP occured <<<-----*** 
        } 
        else 
        { 
         string fileExtension = filePath.Split('.')[filePath.Split('.').Length - 1]; 

         exporter.processIMG(filePath, exportName, "", fileExtension); 
         //need confirmation that exporter.processIMG occured <<<-----*** 
        } 
       } 
      } 
     } 
     catch (Exception e) 
     { 
      Console.WriteLine(
       string.Format("Process terminated. An error has occurred: {0}", e.ToString())); 
     } 
    } 

Answer 1

补充一点：

Console.WriteLine("Done reading & Exporting"); 

上述

} 
catch (Exception e) 
{ 

Answer 2

使用冲洗，然后关闭刻录机的对象。

然后写完成控制台。

Answer 3

当您将文件读到最后并查找匹配项（假设您有类似布尔值的内容以让您知道导出发生并找到匹配项），您可以检查流读取器中的EndOfStream属性并输出消息。或者你可以检查你的匹配值，看它是否返回true。

Answer 4

不要忘记Console.ReadKey（），如果你想真正看到它的存在
