c# - JSON file as database -

i'm tring use json file database static content in asp.net (an image gallery). works well: can read file , retrieve data , display them in easy way. i'm using json.net , c# serverside.

this part of json (hand made):

{     "category 1": [         {             "titlefile": "title of img1",             "filename": "img1",             "urlthumbfile": "content/images/gallery/img1_tb.png",             "urlfile": "content/images/gallery/img1.png",             "descfile": "desc img1"         },         {             "titlefile": "title of img2",             "filename": "img2",             "urlthumbfile": "content/images/gallery/img2_tb.png",             "urlfile": "content/images/gallery/img2.png",             "descfile": "desc img2"          }     ],     "category 2": [         {             "titlefile": "title of img3",             "filename": "img3",             "urlthumbfile": "content/images/gallery/img3_tb.png",             "urlfile": "content/images/gallery/img3.png",             "descfile": "desc img3"         },         {             "titlefile": "title of img4",             "filename": "img4",             "urlthumbfile": "content/images/gallery/img4_tb.png",             "urlfile": "content/images/gallery/img4.png",             "descfile": "desc img4"         }     ],     "category 3": [         {             "titlefile": "title of img5",             "filename": "img5",             "urlthumbfile": "content/images/gallery/img5_tb.png",             "urlfile": "content/images/gallery/img5.png",             "descfile": "desc img5"         }     ] } 

now, figuring how create sort of "upload form", in order write json file , store infos. client side, ok:

<asp:textbox runat="server" id="txtfilename" /> <asp:textbox runat="server" id="txtfiletitle" /> <asp:textbox runat="server" id="txtfiledesc" /> <asp:fileupload runat="server" id="uplfileimg" /> <asp:dropdownlist runat="server" id="ddlcategory"/> <asp:button runat="server" id="btnuploadfile" text="upload" onclick="btnuploadfile_click" /> 

c# side:

//classes public class jsongallerycategory //is correct?? {     public list<jsongallerycontent> category { get; set; }  }  public class jsongallerycontent //?? {     public string filetitle { get; set; }     public string filename { get; set; }     public string urlthumbfile { get; set; }     public string urlfile { get; set; }     public string descfile { get; set; }     public datetime datafile { get; set; } }  //in .aspx.cs private void populateddl() {     list<string> items = new list<string>();     dynamic jsonfile = jobject.parse(utilities.readfile("~/content/images/gallery/gallery.json"));     foreach (jproperty category in jsonfile)     {         items.add(category.name);     }     ddlcategory.datasource = items;     ddlcategory.databind(); }  protected void btnuploadfile_click(object sender, eventargs e) {                if (uplfileimg.hasfile)     {         string filename = path.combine(server.mappath("~/content/images/gallery/"), uplfileimg.filename);         uplfileimg.saveas(filename);         //open jsonfile...read content...deserialize?         dynamic jsonfile = jobject.parse(utilities.readfile("~/content/images/gallery/gallery.json"));         //create new node?         //???          //append new node?          //serialize again , save...? ordering nodes??         utilities.writefile("~/content/images/gallery/gallery.json", jsonconvert.serializeobject("???", formatting.indented));         utilities.showmessage("success");     }     else     {         utilities.showmessage("error");     } } 

how can obtain it?

thanks in advance!

 dynamic jsonfile = jobject.parse(utilities.readfile("~/content/images/gallery/gallery.json"));  using (filestream fs = file.open(@"~/content/images/gallery/gallery.json", filemode.open)) //may have server.mappath using (streamwriter sw = new streamwriter(fs)) using (jsonwriter jw = new jsontextwriter(sw)) {     jw.formatting = formatting.indented;      jsonserializer serializer = new jsonserializer();     serializer.serialize(jw, jsonfile); }
