Using parameter instead of a model definiton-CodePudding

Component is a model,and Storage is one of its definitons.Is there a way to use a parameter instead of Storage?

public IActionResult Filtered(string parameter)

        {
            
            return View(viewModel.Where(x => x.Component.Storage != "").ToList());

        }

CodePudding user response：

I am assuming that parameter is of type string. This is just a sample code. You can customize it to your needs.

var res = from m in viewModel // I don't know what is inside this viewModel
          where !String.IsNullOrEmpty(parameter)
          select m;
  return View(res);

to get the parameter from the url add it to the function

public IActionResult Filtered(string parameter)
{
    return View(viewModel.Where(x => x.Component.Storage != parameter).ToList());
}

You can use reflection to get value by parameter like this


var component = new Component { Storage = "A1" };
var valueOfName = component["Name"];
Console.WriteLine(valueOfName);

public partial class Component
{
    public string Storage { get; set; }

    public object this[string propertyName]
    {
        get
        {
            var type = GetType();
            var property = type.GetProperty(propertyName);
            if (property == null) throw new Exception("Class donesn't have this property");
            var value = property.GetValue(this, null);
            return value;
        }
        private set{};
    }
}

If you can modify the class you don't need the partial key word on Component class
