重新创建一个逗号分隔的文件而没有逗号 [英] Recreate a comma delimited file without the commas

问题描述

大家好，

我是C#的新手，正在尝试将逗号分隔的文件读入fileStream，将逗号替换为空格，然后将fileStream输出到新文件中.但是，当我使用此代码时，输​​出似乎已编码.有什么想法我想念的吗?任何人都可以建议一种更简单的方法，因为我说我是该语言的新手:

Hey all,

I''m totally new to C# and am trying to read a comma delimited file into a fileStream, replace the commas with spaces and output the fileStream into a new file. When I use this code however the output seems to be encoded. Any ideas what I''m missing? Can anyone suggest an easier way of doing this, as I say I''m a total newbie to the language:

private void Read_File(object Sender, EventArgs e)
{
     FileStream fileStream = new FileStream("C:\\commas.txt", FileMode.Open);
     String data = "";
     String data2 = "";
     byte[] bytes = new byte[fileStream.Length];
     try
     {
          using (var sr = new StreamReader(fileStream, Encoding.Unicode)) 
         { 
             data = sr.ReadToEnd(); 
         }
         for (int i = 0; i < data.Length; i++)
         {
             if (data.ElementAt(i).Equals(","))
             {
                 data2 = data2 + " ";
             }
             else
             {
                 data2 = data2 + data.ElementAt(i);
             }
          }
          File.WriteAllText("C:\\nocommas.txt", data2); 
      }
      finally
      {
          fileStream.Close();
      }
  }

任何帮助将不胜感激.

推荐答案

由于您正在使用纯文本"内容，因此可以改用TextReader和TextWriter.那将是简单的方法.您也可以只使用简单的yourCurrentLine.Replace(",", " ")调用来执行转换.
如果文件确实很大，请使用ReadLine方法，如果保证文件长度合理，则可以使用ReadToEnd方法.
TextWriter的MSDN文档 [

Since you are working with Plain Text stuff, you could use a TextReader and TextWriter instead. That would be the simple way. You can also just use a simple yourCurrentLine.Replace(",", " ") call to perform the conversion.
If your file is really large, use the ReadLine approach, if the file is guaranteed to be of a reasonable length, then you can use the ReadToEnd approach.
MSDN Documentation for TextWriter[^]

您可以执行它与以下代码:

You can do it with this code:

private void Read_File(object Sender, EventArgs e)
{
  string contentOfFileWithCommas = File.ReadAllText("C:\\commas.txt",Encoding.UTF8);
  string contentOfFileWithoutCommas = contentOfFileWithCommas.Replace(",", " ");
  File.WriteAllText("C:\\nocommas.txt",contentOfFileWithoutCommas,Encoding.UTF8);
}

希望对您有所帮助.

Hope this helps.

非常感谢Marcus和ProgramFOX.我知道我觉得这太简单了，这让我变得太复杂了.再次感谢.
