创建c# SelectList 不指定值

Question

手动创建 select 列表时，我通常同时拥有文本和值：

SelectList SupplierStatusList = new SelectList(new[] {
            new SelectListItem { Selected = false, Text = "Please Select", Value = "Please Select" },
            new SelectListItem { Selected = true, Text = "1", Value = "1" },
            new SelectListItem { Selected = false, Text = "2", Value = "2" },
            new SelectListItem { Selected = false, Text = "3", Value = "3" },
            new SelectListItem { Selected = false, Text = "4", Value = "4" },
            }, "Value", "Text");

但是如何在不指定值的情况下执行此操作？这留下了我不想要的值=“”。

SelectList SupplierStatusList = new SelectList(new[] {
            new SelectListItem { Selected = false, Text = "Please Select"},
            new SelectListItem { Selected = true, Text = "1"},
            new SelectListItem { Selected = false, Text = "2"},
            new SelectListItem { Selected = false, Text = "3"},
            new SelectListItem { Selected = false, Text = "4"},
            }, "Value", "Text");

有什么想法吗？

抱歉，是的，我希望文本和值相同。

如评论中所建议，您可以使用构造函数重载：

var selectListItems = new[] {"Please Select", "1", "2", "3"};
var selectList = new SelectList(selectListItems, "1");
