推荐答案

@ Html.DropDownListFor(m => m.categories.CategoryID，Model.categories.
. CategoryList，-选择一个-")

@Html.DropDownListFor(m=>m.categories.CategoryID,Model.categories.
CategoryList,"--Select one--")

var list = new [] {
新人员{ID = 1，名称=名称1"}，
新人员{ID = 2，Name ="Name2"}，
新人员{ID = 3，名称=名称3"}
};

var selectList = new SelectList(list，"Id"，"Name"，2);

ViewData ["People"] = selectList;

Html.DropDownList("PeopleClass"，(SelectList)ViewData ["People"])

var list = new[] {
new Person { Id = 1, Name = "Name1" },
new Person { Id = 2, Name = "Name2" },
new Person { Id = 3, Name = "Name3" }
};

var selectList = new SelectList(list, "Id", "Name", 2);

ViewData["People"] = selectList;

Html.DropDownList("PeopleClass", (SelectList)ViewData["People"])
