I have this class:

public class UserFilter
{
    public bool IsShowCars { get; set; } = true;

    public bool IsShowBikes { get; set; } = true;

    public bool IsShowMotorcycles { get; set; } = true;

    public bool IsShowTrucks { get; set; } = false;

    public bool IsShowPlanes { get; set; } = true;

    public bool IsShowTrains { get; set; } = true;
}

And I want to create a checkbox in my .cshtml view file, using CheckBoxFor and a LabelFor, for each property in the class, in order to bind them to the Model. Is there any way of doing that with a Foreach loop, without literally typing each of them like @Html.CheckBoxFor(m => m.Filter.IsToShowCars)?

CodePudding user response：

You can bind a IDictionary<string, bool> in a loop to checkboxes.

public class UserFilter
{
    public bool IsShowCars { get; set; } = true;
    public bool IsShowBikes { get; set; } = true;
    public bool IsShowMotorcycles { get; set; } = true;
    public bool IsShowTrucks { get; set; } = false;
    public bool IsShowPlanes { get; set; } = true;
    public bool IsShowTrains { get; set; } = true;
        
    public IDictionary<string, bool> ToCheckList() 
    {
        // Convert your model to 
        // a 'loopable' collection
        var json = JsonSerializer.Serialize(this);
        var dict = JsonSerializer.Deserialize<IDictionary<string, bool>>(json);
        return dict;
    }

    public static UserFilter FromCheckList(IDictionary<string, bool> dict) 
    {
        // Convert the collection
        // back to your model
        // Attention: this creates a new object!
        var json = JsonSerializer.Serialize(dict);
        return JsonSerializer.Deserialize<UserFilter>(json);
    }
}

Eventually you can change it to fill the existing properties in FromCheckList to the current instance.
