这是我的解决方法：
首先，我有一个UserModel，它定义了您提到的属性。然后，我的控制器准备数据如下：

public IActionResult Privacy()
        {
            List<UserModel> list = new List<UserModel> { 
                new UserModel{ UserId = 1, UserName="user1", Education="primary", Location="steet1"},
                new UserModel{ UserId = 2, UserName="user2", Education="middle", Location="steet2"}
            };
            ViewData["dropdown"] = list;
            return View();
        }

下面是cshtml文件：

@model WebAppMvcJwt.Models.UserModel

<div>
    <select asp-for="@Model.UserId" asp-items="(@ViewData["dropdown"] as IEnumerable<SelectListItem>)" id="UserId" class="form-control ">
        <span asp-validation-for="@Model.UserId"></span>
        @foreach (var item in @ViewData["dropdown"] as IEnumerable<UserModel>)
        {
            <option value="@item.UserId&&@item.Education&&@item.Location">@item.UserName</option>

        }
    </select>
    <input id="education" type="text" />
    <input id="location" type="text" />
</div>

@section Scripts{
    <script>
        $("#UserId").change(function () {
            var selectedid = $("#UserId option:selected").val().split("&&");
            var education = selectedid[1];
            var location = selectedid[2];
            $('#education').val(education);
            $('#location').val(location);
        });
    </script>
}
