我讀了文件，文件格式是該
輸入文件格式

此文件中的同義詞集列應刪除和第二件事，如果Word列有多個詞，那麼id，PosScore，NegScore會按照重複的詞重複一行，但是id，posScore，NegScore會相同。 我想上面的文件
輸出

id   PosScore  NegScore    Word  
00002098 0    0.75    unable#1  
00002312 0.23   0.43    dorsal#2  
00002312 0.23   0.43    abaxial#1  
00002527 0.14   0.26    ventral#2  
00002527 0.14   0.26    adaxial#1  
00002730 0.45   0.32    acroscopic#1  
00002843 0.91   0.87    basiscopic#1  
00002956 0.43   0.73    abducting#1  
00002956 0.43   0.73    abducent#1

00003131 0.15   0.67    adducent#1  

我寫了下面的代碼的下面的輸出，但它會出現意想不到的結果。

TextWriter tw = new StreamWriter("D:\\output.txt");  
private void button1_Click(object sender, EventArgs e) 
     { 

       StreamReader reader = new StreamReader(@"C:\Users\Zia Ur Rehman\Desktop\records.txt"); 
       string line; 
       String lines = ""; 
       while ((line = reader.ReadLine()) != null) 
       { 

        String[] str = line.Split('\t'); 

        String[] words = str[4].Split(' '); 
        for (int k = 0; k < words.Length; k++) 
        { 
         for (int i = 0; i < str.Length; i++) 
         { 
          if (i + 1 != str.Length) 
          { 
           lines = lines + str[i] + ","; 
          } 
          else 
          { 
           lines = lines + words[k] + "\r\n"; 

          } 
         } 
        } 
       } 
      tw.Write(lines); 
      tw.Close(); 
      reader.Close();  
     } 

這個代碼給出的結果是錯誤的

Answer 1

我簡化了你的代碼，並使其能夠正常工作。 它仍然缺少驗證，可以通過使用StringBuilder，尤其是通過將每行寫入文件而不是將其追加到字符串來實現更高性能。它也缺少exception handling。

using (TextWriter tw = File.CreateText(@"c:\temp\result.txt")) 
using (StreamReader reader = new StreamReader(@"stackov1.txt")) 
{ 
    string line; 
    String lines = ""; 
    while ((line = reader.ReadLine()) != null) 
    { 

     String[] str = line.Split('\t'); 

     String[] words = str[3].Split(' '); 
     for (int k = 0; k < words.Length; k++) 
     { 
      lines = lines + str[0] + "\t" + str[1] + "\t" + str[2] + "\t" + words[k] + "\r\n"; 
     } 
    } 
    tw.Write(lines); 
}

所以，這是現在工作。經過長時間的努力。
注意：如果您在輸入文件中沒有使用正確的製表符。結果將不正確。不要忽視正確的標籤。

TextWriter tw = new StreamWriter("D:\\output.txt");  
    private void button1_Click(object sender, EventArgs e) 
    { 
     StreamReader reader = new StreamReader(@"C:\Users\Mohsin\Desktop\records.txt"); 
     string line; 
     String lines = ""; 
     while ((line = reader.ReadLine()) != null) 
     { 

      String[] str = line.Split('\t'); 

      String[] words = str[3].Split(' '); 
      for (int k = 0; k < words.Length; k++) 
      { 
       for (int i = 0; i < 4; i++) 
       { 
        if (i + 1 != 4) 
        { 
         lines = lines + str[i] + "\t"; 
        } 
        else 
        { 
         lines = lines + words[k] + "\r\n"; 

        } 
       } 
      } 
     } 
     tw.Write(lines); 
     tw.Close(); 
     reader.Close(); 
    }
