Argument list using IList in C# asp.net mvc

Question

Hi Team

 

I need some help, want to pass some parameters using List<>(). Here is my sample code.

// controller
public IList<ExtractionViewModel> GetExtractionViewModels(int Week, string Year) // arguments
{
}

// Model properties
public string Year { get; set; }

public int Week { get; set; }

public void ExportToExcel()
{
    var v = new GridView();
    v.DataSource = this.GetExtractionViewModels(); // How to return this argument back as List?
    ....///
}
