StreamReader to find specific text and rewrite file

StreamReader to find specific text and rewrite file


I'm trying to find the best way to read and then find specific text within file and then remove it, using StreamWriter.

I have already created the StreamReader, but now need to find out the best way to find : with the file and remove it, then rewrite file.



RE: StreamReader to find specific text and rewrite file

I might be able to use stringbuilder, if I know that my file will always have the : on the forth line, can I only replace it with a blank line, and not other lines that contain :, because the another lines have the word cn:, which is correct and not a line that starts with :

static string MinifyB(string p)
    StringBuilder b = new StringBuilder(p);
    b.Replace("  ", string.Empty);
    b.Replace(Environment.NewLine, string.Empty);
    b.Replace("\\t", string.Empty);
    b.Replace(" {", "{");
    b.Replace(" :", ":");
    b.Replace(": ", ":");
    b.Replace(", ", ",");
    b.Replace("; ", ";");
    b.Replace(";}", "}");
    return b.ToString();
