带有空选项行的ASP.NET MVC下拉列表

Question

@Html.LabelFor(model => model.Employee_No)      
@Html.DropDownListFor(model => model.Employee_No,
new SelectList(ViewBag.EmployeeList, "Value", "Text"),
"Choose Employee",
new { @class = "ui selecetion dropdown" })

我想让它写一行空白，但它没有出现。它不是空行，而是在下拉列表中写入，但我无法将其选为行。

Answer 1
