Strip double quotes from a string in .NET

Question

I\'m trying to match on some inconsistently formatted HTML and need to strip out some double quotes.

Current:

Answer 1

If you only want to strip the quotes from the ends of the string (not the middle), and there is a chance that there can be spaces at either end of the string (i.e. parsing a CSV format file where there is a space after the commas), then you need to call the Trim function twice...for example:

string myStr = " \"sometext\"";     //(notice the leading space)
myStr = myStr.Trim('"');            //(would leave the first quote: "sometext)
myStr = myStr.Trim().Trim('"');     //(would get what you want: sometext)

Answer 2

I think your first line would actually work but I think you need four quotation marks for a string containing a single one (in VB at least):

s = s.Replace("""", "")

for C# you'd have to escape the quotation mark using a backslash:

s = s.Replace("\"", "");

Answer 3

I didn't see my thoughts repeated already, so I will suggest that you look at string.Trim in the Microsoft documentation for C# you can add a character to be trimmed instead of simply trimming empty spaces:

string withQuotes = "\"hellow\"";
string withOutQotes = withQuotes.Trim('"');

should result in withOutQuotes being "hello" instead of ""hello""

Answer 4

s = s.Replace("\"", "");

You need to use the \ to escape the double quote character in a string.

Answer 5

if you would like to remove a single character i guess it's easier to simply read the arrays and skip that char and return the array. I use it when custom parsing vcard's json. as it's bad json with "quoted" text identifiers.

Add the below method to a class containing your extension methods.

  public static string Remove(this string text, char character)
  {
      var sb = new StringBuilder();
      foreach (char c in text)
      {
         if (c != character)
             sb.Append(c);
      }
      return sb.ToString();
  }

you can then use this extension method:

var text= myString.Remove('"');

Answer 6

s = s.Replace("\"",string.Empty);
