Question

I’m taking a URL that looks like this:

some_site.com/full/path/page.aspx?label[0]=a_value&label[1]=b_value&label[2]=c_value

The indexed number is generated, so there’s a dynamic number of these ‘label[x]’ values every time.

What would the simplest way of parsing these all into a String[] named ‘Label’ in ASP/C#.NET 4.0?

Answer 1

You should use a NameValueCollection instead of array of Strings.

NameValueCollection queryParameters = new NameValueCollection();
string[] querySegments = queryString.Split('&');
foreach(string segment in querySegments)
{
   string[] parts = segment.Split('=');
   if (parts.Length > 0)
   {
      string key = parts[0].Trim(new char[] { '?', ' ' });
      string val = parts[1].Trim();

      queryParameters.Add(key, val);
   }
}

To get the number of the label withing the square brackets, use Regular Expressions.

regxObj = new Regex(@"\[(.*?)\]");
