问题

To disable the item editor and enable writing only from 4pm to 11:59 pm in an ASP.NET MVC view, you can use the following code:

<div class="form-group">
    @Html.LabelFor(model => model.TESTS_EVENING, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @if (DateTime.Now.TimeOfDay >= TimeSpan.FromHours(16) && DateTime.Now.TimeOfDay <= TimeSpan.FromHours(23, 59))
        {
            @Html.EditorFor(model => model.TESTS_EVENING, new { htmlAttributes = new { @class = "form-control" } })
        }
        else
        {
            @Html.TextBoxFor(model => model.TESTS_EVENING, new { @class = "form-control", @readonly = "readonly" })
        }
        @Html.ValidationMessageFor(model => model.TESTS_EVENING, "", new { @class = "text-danger" })
    </div>
</div>

This code checks if the current time is between 4:00 PM and 11:59 PM. If it is, it enables the item editor; otherwise, it makes the editor read-only.

<div class="form-group">
    @Html.LabelFor(model => model.TESTS_EVENING, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @Html.EditorFor(model => model.TESTS_EVENING, new { htmlAttributes = new { @class = "form-control" } })
        @Html.ValidationMessageFor(model => model.TESTS_EVENING, "", new { @class = "text-danger" })
    </div>
</div>

If Datetime.Now between 16:00 and 23:59

以下是您要翻译的代码部分：

查看示例中的代码：

@{ 
    TimeSpan start = new TimeSpan(16, 0, 0); 
    TimeSpan end = new TimeSpan(23, 0, 0);
    TimeSpan now = DateTime.Now.TimeOfDay;
}
        
if ((now > start) && (now < end))
{
    @Html.EditorFor(model => model.TESTS_EVENING, new { htmlAttributes = new { @class = "form-control", disabled= "disabled" } })
}
else{
    @Html.EditorFor(model => model.TESTS_EVENING, new { htmlAttributes = new { @class = "form-control" } })
}

希望这能帮助您。

   @{ 
  TimeSpan start = new TimeSpan(16, 0, 0); 
    TimeSpan end = new TimeSpan(23, 0, 0);
    TimeSpan now = DateTime.Now.TimeOfDay;
    }
    
    if ((now > start) && (now < end))
    {
               @Html.EditorFor(model => model.TESTS_EVENING, new { htmlAttributes = new { @class = "form-control",disabled= "disabled" } })
 
    
    }
    else{
       @Html.EditorFor(model => model.TESTS_EVENING, new { htmlAttributes = new { @class = "form-control"} })
    
    }
