<select id="task_isfirst" class="form-control savedata" > @if (Model.isfirst == true) { <option value=‘true‘ selected=‘selected‘>是</option> <option value=‘false‘ >否</option> } else { <option value=‘true‘>是</option> <option value=‘false‘ selected=‘selected‘>否</option> } </select>
注意：else前面不用加@
ASP.NET Razor - html中使用if else
