I have this url http://spdata.com?value=1&rem=288&data=1 ..I want to replace the rem=288(this 288 is not static ) with some other value like membership=1 .Can someone tell me how to do this. Was thinking about doing a substring and then combining but not sure if there is an already easy process to do this .
Thanks
You can do it with regular expressions.
Something like this:
using System.Text.RegularExpressions;
string newUrl= Regex.Replace("http://spdata.com?value=1&rem=288&data=1", @"rem=\d*", "membership=1",RegexOptions.IgnoreCase);
This should work for you.According to your url pattern, this will change all "rem=x" with another value.In this case it is "membership=1",ofcourse you can make it dynamic too.
var url = "http://spdata.com?value=1&rem=288&data=1";
var parts = url.Split('&').Select(x =>
{
if (x.Contains("rem=")) return "membership=1";
return x;
});
var result = string.Join("&", parts);
Try To use This
string text = "membership=1";
string x = "http://spdata.com?value=1&rem=288&data=1 ";
int y = x.IndexOf("rem=");
string z = x.Substring(y, x.Length - y);
int a = z.IndexOf("&");
string url = x.Substring(0, y) + text + z.Substring(a, z.Length - a);
If you want easy, quick and readable then why not just concatenate the strings together? Or use string.Format
string key="rem";
string value="288";
string.Format("http://spdata.com?value=1&{0}={1}&data=1", key, value)
Uri uri = new Uri("http://spdata.com?value=1&rem=288&data=1...")
var pairs = HttpUtility.ParseQueryString(uri.Query)
pairs.Remove("rem");
pairs.Add("membership", "1");
var builder = new UriBuilder(uri);
builder.Query = pairs.ToString();
Uri modified = builder.Uri;
