    Resolved [RESOLVED] Read JSON file and Add ComboBox

    I am a novice, I try to create a software that allows me to automatically download videos from a database, I managed to extract the information from the database and create a URL, which downloads a JSON file, within the JSON there are URL's of the videos in different resolutions.

    I am trying to read the JSON file now. I would like it to read all the JSON files that I have in a folder, one by one, and if the user before all this process has selected the 720p resolution for the videos, just read the "progressiveDownloadURL": "https:// download -a.akamaihd.net/files/media_publication/bc/sjjm_S_138_r720P.mp4" from "label": "720p". And then download the video. This is what I have so far:

    Code:
    'Leer archivo JSON
        Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
    
        End Sub
    
        Public Class File
            Public Property progressiveDownloadURL As String
            Public Property checksum As String
            Public Property filesize As Integer

        End Class
    Do you know how I can read the progressiveDownloadURL along with the respective label? You can see the original JSON here. Here is the JSON of the first video:

    }
    I want that if in a ComboBox, I select 720p, it downloads the video from the progressiveDownloadURL that says "label": "720p", that it downloads all the JSON files one by one. if I make myself understood? I would really appreciate your code input.

    Re: Read multiple JSON files

    I am trying to read the JSON file now. I would like it to read all the JSON files that I have in a folder, one by one, and if the user before all this process has selected the 720p resolution for the videos, just read the "progressiveDownloadURL": "https:// download -a.akamaihd.net/files/media_publication/bc/sjjm_S_138_r720P.mp4" from "label": "720p". And then download the video. This is what I have so far:

    Code:
    'Leer archivo JSON

        End Sub

    Do you know how I can read the progressiveDownloadURL along with the respective label? You can see the original JSON here. Here is the JSON of the first video:

    }
    I want that if in a ComboBox, I select 720p, it downloads the video from the progressiveDownloadURL that says "label": "720p", that it downloads all the JSON files one by one. if I make myself understood? I would really appreciate your code input.
    Assuming you have added a reference to Newtonsoft.Json then the following code should read all .json files in the same folder as the executable (probably a bad idea, put the files somewhere better) and then query them for the 720p label, returning a list of the urls.

    Code:
     Dim files As New List(Of Medium)
            Dim jsonFiles = Directory.GetFiles(".", "*.json")
    
            For Each jsonFile In jsonFiles
                Using reader = New StreamReader(jsonFile)
                    Dim json = Await reader.ReadToEndAsync()
                    Dim file = JsonConvert.DeserializeObject(Of ReadJson)(json)
                    If file.media IsNot Nothing Then
                        files.AddRange(file.media)
                    End If
                End Using
            Next
    
            Dim res = files.SelectMany(Function(m) m.files).Where(Function(m) m.label = "720p").Select(Function(x) x.progressiveDownloadURL).ToList()

    Re: Read multiple JSON files

    I'm trying to see the list items with this, but it gives me the next error: The argument "Prompt" cannot be converted to type "String".

    Which line is throwing that error?

    The attachment isn't working, however files is a list of Medium objects, not sure what you are expecting MsgBox to display. Also as this is VB.Net you might be better off using MessageBox.Show rather than the legacy MsgBox function.

    Re: Read multiple JSON files

    What I expect the MsgBox to show is the progressiveDownloadURL (https://download-a.akamaihd.net/file..._138_r720P.mp4), to see that there are no errors, and then use DownloadFile to download all the videos from the files List. But I can't be successful.

    I have uploaded the image in the original resolution to my server, click here to see the error.

    Re: Read multiple JSON files

    Done, I've done it!!! It gives me all the URLs of all the JSON files in 720p, you're great man!!!

    I did it with this code snippet:
    Code:
    MessageBox.Show(String.Join(",", res))
    Now, I will try to download the videos

    Re: Read multiple JSON files

    Hi, now I have this JSON:

    languages.json

    And I have the next class:

    Code:
    Public Class Language
            Public Property symbol As String
            Public Property langcode As String
            Public Property name As String
            Public Property vernacularName As String
            Public Property script As String
            Public Property altSpellings As String()
            Public Property direction As String
            Public Property isSignLanguage As Boolean
            Public Property isCounted As Boolean
            Public Property hasWebContent As Boolean
        End Class
    
        Public Class Idiomas
            Public Property status As Integer
            Public Property languages As Language()
            Public Property localizedCount As String
        End Class
    I want to get just the vernacularName and add it to a ComboBox as an option, but I'm not successful.

    What have you tried so far? When you say you weren't successful what happened and how did it differ to what you expected to happen?

    The error is in adding to ComboBox1, it does not add it.
