请尝试下面的示例。
查看模型：

public class SomeViewModel
{
    public string Description { get; set; }
    public DateTime SearchDate { get; set; }    
}

控制器方法：

public IActionResult Index()
{
    var model = new SomeViewModel()
    {
        Description = "description 123",
        SearchDate = DateTime.Now
    };
    return View(model);
}

[HttpPost]
public IActionResult EOMOrdersLoad(SomeViewModel data)
{
    //... your code here
    return RedirectToAction("Index", data);
}

而Index.cshtml视图：

@model Models.SomeViewModel

<form id="form" asp-action="EOMOrdersLoad">
    <div >
        <label asp-for="Description" class="form-label">
            @Html.DisplayNameFor(model => model.Description)
        </label>
        <textarea asp-for="Description" class="form-control" id="exampleFormControlTextarea1" ></textarea>
        <span asp-validation-for="Description" class="invalid-feedback"></span>
    </div>
    <div>
        <label asp-for="SearchDate" class="form-label">
            @Html.DisplayNameFor(model => model.SearchDate)
        </label>
        <input asp-for="SearchDate" type="date" class="form-control" >
    </div>
    <br>
    <div>
        <input type="submit" value="Save" />
    </div>
</form>
