如何從文本文件中刪除所有雙引號和完美格式的所有內容

Question

我想從我的下面的文本文件中刪除雙引號。我需要使用我的C＃應用​​程序輸入文件並讀取文本文件，然後刪除所有雙引號並輸出結果。 我需要刪除所有的引號，並使它們成爲完美的四種格式 那麼我該如何做到這一點。

輸入文件

    "C10" "CAP4522,1n,50V.0603" "CAPC1608N" "109.163" "73.025" 

我的代碼從我的C＃應用​​程序來輸入文本文件：

private void convert_Click(object sender, EventArgs e) 
{ 
    OpenFileDialog ofd = new OpenFileDialog(); 
     ofd.InitialDirectory = @"C:\files"; 
     ofd.Filter = "TXT files (*.txt)|*.txt"; 
     ofd.FilterIndex = 2; 
     ofd.RestoreDirectory = true; 
     if (ofd.ShowDialog() == DialogResult.OK) 
     { 
      int[] cols = new int[] { 15, 30, 15, 20, 12 }; 
      string[] strLines = System.IO.File.ReadAllLines(fileName); 

      StringBuilder sb = new StringBuilder(); 
      string line = string.Empty; 
      for (int i = 0; i < strLines.Length; i++) 
      { 
       line = RemoveWhiteSpace(strLines[i]).Trim(); // here i am getting error in RemoveWhiteSpace, that it is not in the context 
       string[] cells = line.Replace("\"", "").Split(new string[] { " " }, StringSplitOptions.None); 
       for (int c = 0; c < cells.Length; c++) 
        sb.Append(cells[c].PadRight(cols[c])); 
       sb.Append("\r\n"); 
      } 

      //System.IO.File.WriteAllText(fileName, sb.ToString()); 
      MessageBox.Show(sb.ToString()); 
     } 
} 

我怎樣才能做到這一點？請幫助我。

我想獲得我輸入的所有文本文件的下面樣式的格式。所以對於上面的文本文件我想要得到的格式如下所示

     C3  CAP,1n,50V.0603  CAPC1608N  101.543   73.025 
     C7  CAP,1n,50V.0603  CAPC1608N  103.448   73.025

Answer 1

嘗試這個例子，這將刪除雙引號並重新格式化您的文本。

private void Reformat(string fileName) 
{ 
    //Give the column width according to column index. 
    int[] cols = new int[] { 12, 35, 25, 15, 15 }; 
    string[] strLines = System.IO.File.ReadAllLines(fileName); 

    StringBuilder sb = new StringBuilder(); 
    string line = string.Empty; 
    string LastComment = string.Empty; 
    string CarouselName = "Carousel"; 
    int iCarousel = 0; 

    for (int i = 0; i < strLines.Length; i++) 
    { 
     line = RemoveWhiteSpace(strLines[i]).Trim(); 
     string[] cells = line.Replace("\"", "").Split('\t');      
     for (int c = 0; c < cells.Length; c++) 
      sb.Append(cells[c].Replace(" ", "_").PadRight(cols[c])); 

     if (cells.Length > 1) 
     { 
      if (cells[1] != LastComment & i > 0) 
      { 
       iCarousel++; 
       if (iCarousel > 45) 
        iCarousel = 1; 
       LastComment = cells[1]; 
      } 

      if (i == 0) 
       sb.Append("Location".PadRight(15)); 
      else 
       sb.Append(String.Format("{0}:{1}", CarouselName, iCarousel).PadRight(15)); 
     } 
     sb.Append("\r\n"); 
    } 

    //System.IO.File.WriteAllText(fileName, sb.ToString()); 
    MessageBox.Show(sb.ToString()); 
} 


private string RemoveWhiteSpace(string str) 
{ 
    str = str.Replace(" ", " "); 
    if (str.Contains(" ")) 
     str = RemoveWhiteSpace(str); 
    return str; 
} 

Answer 2

這兩個步驟是讀取文件並用空白替換引號。

string allText = File.ReadAllText(ofd.FileName); //read file 
string noQuotes = allText.Replace("\"", ""); //replace text 

字符串是不可變這就是爲什麼Replace返回一個新字符串對象，而不是簡單地改變現有allText字符串。

或者，您可能希望使用ReadAllLines，它將返回一個字符串數組，其中每個元素都是文本文件的一行。理論是一樣的，但你會遍歷數組並用空字符串替換每個元素中的引號。

如果你想使用ReadAllLines和WriteAllLines（保存文件出來），你可以這樣做

File.WriteAllLines(@"saveFile.txt", File.ReadAllLines(ofd.FileName) 
            .Select(s => s.Replace("\"", "")).ToList()); 

，將做閱讀，更換，並在一條線（不是更少數量的節約線條總是更好）。

Answer 3

我會做這種方式：

using System.IO; 

File.WriteAllText(@"C:/text2.txt", File.ReadAllText(@"C:/text1.txt").Replace("\"", "")); 

更新：更短的解決方案

Answer 4

你可以用正則表達式做到這一點很容易：

using System.IO; 
using System.Text.RegularExpressions; 

if (ofd.ShowDialog() == DialogResult.OK) 
{ 
    string withoutQuotes = Regex.Replace(File.ReadAllText(ofd.FileName), "\"", ""); 
    File.WriteAllText(ofd.FileName, withoutQuotes); 
}
