Handling a comma inside a cookie value using C# and .NET 6

Question

I encountered an issue while trying to read the content of a third-party cookie.

The cookie contains values like: 110, IN, ABC, X, Y,,,,,

I'm reading the cookie using:

_httpContextAccessor.HttpContext.Request.Cookies["key"];

But it did not return all the data.

Note: this is third-party cookie and I can not encode it to get rid of it.

Answer 1

I got a fix: instead of getting cookie value like

Get as below:

 private string ParseCookie(string cookieKey)
 {
    var cookieHeader = 
    _httpContextAccessor.HttpContext.Request.Headers["Cookie"].ToString();
    if (!string.IsNullOrEmpty(cookieHeader))
    {
       // Split the cookies by ';' which is the delimiter for multiple cookies
       var cookies = cookieHeader.Split(';');
       foreach (var cookie in cookies)
       {
        // Split the individual cookie by '='
        var parts = cookie.Split('=');
        if (parts.Length == 2)
        {
            var key = parts[0].Trim();
            var value = parts[1].Trim();

            if (key == cookieKey)
            {
                // Process the comma-separated value
                return Uri.UnescapeDataString(value);
                // Perform any necessary actions based on the cookie value
                break;
            }
        }
    }
  }
  return String.Empty;
}
