Trying to search two strings in a document in the same line

            WebClient wb = new WebClient();
            string License = wb.DownloadString("DocumentSite");
            if (License.Contains(LK.Text + UN.Text))

I want to search line by line and not the whole document

>Solution :

You can use the StringReader to step through the string line by line.

private async Task ReadLicenseAsync(string license)
{
  using var textReader = new StringReader(license);
  string line = string.Empty;
  while ((line = await textReader.ReadLineAsync()) != null)
  {
    // TODO::Handle line
  }
}
