I want to extract the original link from a string. The string contains something like this

{
    "upload": {
        "image": {
            "name": false,
            "title": "",
            "caption": "",
            "hash": "cSNjk",
            "deletehash": "ZnKGru1reZKoabU",
            "datetime": "2010-08-16 22:43:22",
            "type": "image\/jpeg",
            "animated": "false",
            "width": 720,
            "height": 540,
            "size": 46174,
            "views": 0,
            "bandwidth": 0
        },

You could probably do it using a regular expression or String.IndexOf and Substring.

I have no experience in Regular Expression or String.IndexOf. Can you please elaborate a little bit?

Solution 1

You can read this file line by line, or if it's a string, Split[^] it on Environment.NewLine. Then you can take each string and check if it contains your key, such as 'original'. If it does, you can split on the : and then grab the second string, or just Replace[^] "Original": with string.Empty. You can then replace " with string.Empty, and you will have your URL. It looks like you need to replace \/ with /, also.

I think you can use Remove() function for it.remove the index of "original".See how to use Remove()..

Solution 3

This looks like JSON data.
Get a JSON parser.
http://json.org/[^]
Near the bottom of the page there is a big list of JSON implementations.
Or see: JSON Serialization and Deserialization in ASP.NET[^]
