如何删除列表中包含的单词 <string> 从Textile删除deleteList

Question

I am wondering how can i delete words from my text file which are already contained in my List<string> deleteCodeList = new List<string>(); . here i already have a large numbers of words in my deleteCodeList, and i want to search for this each words, if words contained then i want to delete that line . My text file is tab delimited .

Codes:-

      while (!reader.EndOfStream)
            {
                var line = reader.ReadLine();
                var value = line.Split('\t');
               // here i am able to do words without double quotes
                bool deleteLine = value.Any(v => deleteCodeList.Any(w => v.Equals(w)));
                if (!deleteLine)
                {
                    sb.Append(line + Environment.NewLine);
                }
                //here i am able to do words with double quotes
                var values = line.Split('\t').Select(v => v.Trim(' ', '"'));
                bool deleteLines = values.Any(v => deleteCodeList.Any(w => v.Equals(w)));
                if (!deleteLines)
                {
                    sb.Append(line + Environment.NewLine);
                }
            }

My input text file

In your second while() loop, you don't do anything with values or sb , returning an empty string to be written. You want to check if any of the tab-separated words are in your deleteCodeList , and if not, add it to the stringbuilder:

while (!reader.EndOfStream)
{
    var line = reader.ReadLine();
    var values = line.Split('\t').Select(v => v.Trim(' ', '"'));

    bool deleteLine = values.Any(v => deleteCodeList.Any(w => v.Equals(w)));

    if (!deleteLine)
    {
        sb.Append(line + Environment.NewLine);
    }
}
