Public Function GenerateSelect (viewContext As ViewContext, modelExplorer As ModelExplorer, optionLabel As String, expression As String, selectList As IEnumerable(Of SelectListItem), allowMultiple As Boolean, htmlAttributes As Object) As TagBuilder

参数

viewContext: ViewContext

ViewContext当前范围的实例。

modelExplorer: ModelExplorer

ModelExplorer expression的。如果 null为，则使用 viewContext 和 expression确定验证属性。

optionLabel: String

默认空 <选项> 元素的可选文本。

expression: String

表达式名称，相对于当前模型。

selectList: IEnumerable<SelectListItem>

对象的集合SelectListItem，用于使用 <optgroup> 和 <option> 元素填充 <select> 元素。如果 null为，则会在 ViewContext.ViewData[expression]中找到此集合。

allowMultiple: Boolean

如果 true为，则包含 multiple 生成的 HTML 中的属性。否则，生成单 <选选择选择> 元素。

htmlAttributes: Object

一个 Object ，它包含 select> 元素的 <HTML 属性。或者，一个 IDictionary<TKey,TValue> 包含 HTML 属性的实例。

TagBuilder

描述 <select> 元素的新TagBuilder。
