 @ {
 var listItems = new List< System.Web.UI.WebControls.ListItem> {new System.Web.UI.WebControls.ListItem {Text =Acceptable，Value =Acceptable}，
 new System.Web.UI.WebControls.ListItem {Text =Good，Value =Good }，
 new System.Web.UI.WebControls.ListItem {Text =Excellent，Value =Excellent}}; 
} 
 @ Html.DropDownList（RiskCriteria，新的SelectList（listItems），
 new {@onchange =onRiskChange（this.options [this.selectedIndex] .value）;} ）
