在此文件中，Synset列应该被删除，第二件事如果Word列有多个单词，那么id，PosScore，NegScore将根据单词重复行重复，但id，posScore，NegScore将是相同。我想要上面文件的以下输出
输出

我写下面的代码，但它给出了意想不到的结果。

 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();    
        }

此代码提供以下错误的结果

Answer 1

所以，现在正在运作。经过长时间的努力。
注意：如果您未在输入文件中使用正确的标签。结果将是不正确的。不要忽视正确的标签。

  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();
  }

Answer 2

我简化了您的代码并使其正常工作。它仍然缺乏验证，使用StringBuilder可以更高效，特别是通过将每行写入文件而不是将其附加到String。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);
}
