C# 在C语言中读取文件并提取单词而不使用#的程序#

我读了一个文件，文件格式是这样的

在这个文件中，Synset列应该是delete，其次，如果单词列有多个单词，那么id，PosScore，NegScore将根据一行中的单词repeat重复，但是id，PosScore，NegScore将是相同的。 我想要上述文件的以下输出
输出

我编写了以下代码，但它给出了意外的结果

 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();    
        }

我简化了您的代码并使其正常工作。 它仍然缺乏验证，通过使用

StringBuilder

可以提高性能，尤其是通过将每一行写入文件而不是将其附加到字符串。它还缺少异常处理

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);
}

使用（TextWriter tw=File.CreateText（@“c:\temp\result.txt”））
使用（StreamReader=newstreamreader（@“stackov1.txt”））
{
弦线；
字符串行=”；
而（（line=reader.ReadLine（））！=null）
{
字符串[]str=line.Split（'\t'）；
String[]words=str[3]。拆分（“”）；
for（int k=0；k

所以，现在可以使用了。经过长期的努力工作
注意：如果在输入文件中没有使用正确的制表符。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();
  }

TextWriter tw=新的StreamWriter（“D:\\output.txt”）；
私有无效按钮1\u单击（对象发送者，事件参数e）
{
StreamReader=新的StreamReader（@“C:\Users\Mohsin\Desktop\records.txt”）；
弦线；
字符串行=”；
而（（line=reader.ReadLine（））！=null）
{
字符串[]str=line.Split（'\t'）；
String[]words=str[3]。拆分（“”）；

什么是“意外”？你如何知道新专栏何时开始？@Magnus我现在编辑它，你可以see@GertArnold我现在编辑它，你可以看到意想不到的结果，除了

str[4]

之外，一切都很好。我想应该是

str[3]

我添加了编写器和读取器代码，所以现在我的示例已经完成（在需要初始化IO之前）。请发布详细信息如果itSir i add IO有问题，但它没有写入文件ZIA，请用数据文件的完整路径替换stackov1.txt。另外，请使用调试器检查代码的错误。

  TextWriter tw = new StreamWriter("D:\\output.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++)

                    }
                    else

                    }
