Deserialize json file and place the data to textbox

Question

Hi

I have a JSON file with the following information :
{
"WindowsCustomization": [
{
"id": 1,
"Item": "Disable Windows 10 Tablet Mode, Use desktop mode and Don't ask me and don't switch.",
"value": "True"
},
{
"id": 2,
"Item": "Show the touch keyboard when not in tablet mode and there's no keyboard attached.",
"value": "True"
}
]
}

I have a problem with Deserialize it using Newtonsoft and place the item value to the label text.
Is anybody can help me with this? Thanks in advance

Hi MIndraRuslan-8520,
First, you need to create the class, which represents the data in JSON.
I created two classes: the WCustomizationis for the outer fields (WindowsCustomization) and a list of objects of type Item.
Here is my test code you can refer to.

private void Form1_Load(object sender, EventArgs e)  
{  
    string jsonFile = File.ReadAllText(@"C:\Users\Desktop\test.json");//change to your json file  
    var json= JsonConvert.DeserializeObject<WCustomization>(jsonFile);     
    label1.Text = json.WindowsCustomization[0].Item;  
    label2.Text= json.WindowsCustomization[1].Item;  
  
}  
}  
public class items  
{  
public int id { get; set; }  
public string Item { get; set; }  
public string value { get; set; }  
         
}  
class WCustomization  
{  
          
public List<items> WindowsCustomization { get; set; }  
}

Hi Daniel,

Thanks for your reply, but there is a problem. I got the following issue :
"System.ArgumentOutOfRangeException: 'Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index'
