如何根据条件要求填写实体属性-- ASP NET核心MVC和实体框架

public IActionResult FillEntityProperty(int id, string name)
{
    // 根据id获取实体对象
    var entity = dbContext.Entities.FirstOrDefault(e => e.Id == id);

    if (entity != null)
    {
        // 根据条件要求填写实体属性
        entity.Name = name;

        // 保存更改
        dbContext.SaveChanges();
    }

    return RedirectToAction("Index");
}

<form asp-action="FillEntityProperty" method="post">
    <div class="form-group">
        <label for="id">实体ID：</label>
        <input type="text" class="form-control" id="id" name="id" required>
    </div>
    <div class="form-group">
        <label for="name">实体名称：</label>
        <input type="text" class="form-control" id="name" name="name" required>
    </div>
    <button type="submit" class="btn btn-primary">提交</button>
</form>

routes.MapRoute(
    name: "fillEntityProperty",
    template: "entity/fillproperty",
    defaults: new { controller = "Entity", action = "FillEntityProperty" }
);
