枚举的类型
本文关键字:类型 枚举 | 更新日期: 2023-09-27 17:57:06
我正在尝试从此方法制作一个通用方法:
public static SelectList LanguagesToSelectList()
{
return new SelectList(
Enum.GetValues(typeof(Languages))
.Cast<Languages>()
.Select(g => new KeyValuePair<Languages, string>(
g,
Resources.Views_GamesAndApplications.ResourceManager.GetString("Language_" + g.ToString()
)
)),
"Key",
"Value"
);
}
这是我得到的:
public static SelectList ToSelectList(Enum enumType, ResourceManager resourceManager, string resourcePrefix)
{
return new SelectList(
Enum.GetValues(typeof(enumType))
.Cast<enumType>()
.Select(g => new KeyValuePair<enumType, string>(
g,
resourceManager.GetString(resourcePrefix + g.ToString())
)),
"Key",
"Value");
}
但是,enumType 不应该是 Enum
型(也不应该是 Type
型),我无法弄清楚应该是什么类型,或者我是否应该改写整个方法。
使用示例(符合给定的答案):
@Html.DropDownListFor(
m => m.Language,
SelectListHelper.ToSelectList<Languages>
(Resources.Views_GamesAndApplications.ResourceManager,"Language_"))
谢谢。
public static SelectList ToSelectList<T>(ResourceManager resourceManager, string resourcePrefix)
where T : struct
{
return new SelectList(Enum.GetValues(typeof(T)).Cast<T>()
.Select(g => new KeyValuePair<T, string>(g, resourceManager.GetString(resourcePrefix + g.ToString()))), "Key", "Value");
}
//Example:
var list = ToSelectList<Languages>(someResourceManager, "somePrefix");
