        {
            List<decimal> valX = new List<decimal>();
            decimal d1 = 2.01m;
            decimal d2 = 4.02m;
            decimal d3 = 6.06m;
            decimal d4 = 8.02m;

            List<decimal> valY = new List<decimal>();
            decimal dd1 = 10.24m;

Hi, sy_60

I modified your code according to your needs, please refer to it.
For more information on how to bind the model, you can refer to the two links: link1,link2.

Controller

public ActionResult Index()
{
     List<XY> FillDatalist = new List<XY> { 
          new XY{X=2.01m,Y=10.24m},
          new XY{X=4.02m,Y=21.12m},
          new XY{X=6.06m,Y=31.07m},
          new XY{X=8.02m,Y=42.04m}
     };
     return View(FillDatalist);
}

Index

@model IEnumerable<WebApplication1.Models.XY>

@if (Model.Count() > 0)
{
    <hr />
    <table class="table">
        @foreach (var item in Model)
        {
            <tr>
                <td>@item.X</td>
                <td>@item.Y</td>
            </tr>
        }
    </table>

}

Here is the result.

Best Regards,

YihuiSun
