Question

我需要编写一个返回下一个10年选择列表的函数.我现在很难编码,仍然在努力完成这项工作.如何编写一个可以返回我想要的任何时期的函数,例如未来20年

//View
@Html.DropDownListFor(model => model.CardExpiryYear, vmConstants.listExpiryYears)

//Partial Class
public static partial class vmConstants
{
public static SelectList listExpiryYears = new SelectList(new[]
        {
                new{  Name ="" , ID = ""}, 
                new{  Name ="2014" , ID = "2014"}, 
                new{  Name ="2015" , ID = "2015"}, 
                new{  Name ="2016" , ID = "2016"}, 
                new{  Name ="2017" , ID = "2017"}, 
                new{  Name ="2018" , ID = "2018"}, 
                new{  Name ="2019" , ID = "2019"}, 
                new{  Name ="2020" , ID = "2020"}, 
                new{  Name ="2021" , ID = "2021"}, 
                new{  Name ="2022" , ID = "2022"}, 
                new{  Name ="2023" , ID = "2023"}, 
                new{  Name ="2024" , ID = "2024"}, 
                new{  Name ="2025" , ID = "2025"},
                new{  Name ="2026" , ID = "2026"},
        },
        "ID", "Name", 1);
}

你应该能够使用Enumerable.Range和DateTime.Now.Year.这样的事情应该让你开始.

var years = Enumerable.Range(DateTime.Now.Year, 10);
var select = new SelectList(years.Select(y => new SelectListItem() 
{ 
    Text = y.ToString(), Value = y.ToString() 
}));
