Need help with this string.

Pretty much I need to detect if this exact string exists, however the numbers can be anything.

How can i do this using regex? Thanks

PHP Code


<?php 
string PageEnd = "{\"total\":335,\"items\":[]}"; 


Below doesn't work... but it's what im trying to do

PHP Code


<?php 
Regex r = new Regex("{\"total\":" + @"^\d+$" + ",\"items\":[]}");
if (r.Match(stringImComparing).Success)
{
//do stuff
} 


Current work-around:

PHP Code


<?php 
string PageEnd = "items\":[]}";
if (ReturnedHTML.Contains(PageEnd))
{
// Console.WriteLine("Found End Page");
MaxPage = k;
}

Code

Try
    If Regex.IsMatch( "{\""total\"":335,\""items\"":[]}", "\{\\""total\\"":[^]\n\r"",:[\\eimst}]{3},\\""items\\"":\[\]\}") Then
        ' Successful match
    Else
        ' Match attempt failed
    End If
Catch ex As ArgumentException
    'Syntax error in the regular expression
End Try

This isn't a task for regex mate, use a json deserializer to check or just use string#Contains to check if the two keys exists

JSON deserialization would be much better. Add a reference to System.Web.Extensions and then you can use the System.Web.Script.Serialization.JavaScriptSerializer class.

pcre php regex

Code

([{].{2}total.{2}[:]\d{3}.{3}items.{3}[[][]][}])

however i do suggest deserialization as well :)

Sorry for the off-topic, but I have a question:

Are there any advantages referencing to System.Web.Extensions for using System.Web.Script.Serialization.JavaScriptSerializer instead adding a reference to System.Runtime.Serialization for using System.Runtime.Serialization.Json.DataContractJsonSerializer class?

Or maybe both classes 'do the same' job? (serialize/deserialize JSON data)

PS: I've always used DataContractJsonSerializer class for JSON stuff.

I haven't used the latter that much and I am more familiar with the first. As far as advantages go I have no clue.
