C#SortedList如何按值获取密钥？

Question

有一个 SortedList

slLanguage = new SortedList();
slLanguage.Add("Bahasa","id-ID");
slLanguage.Add("Chinese Simplified(????)","zh-CN");
slLanguage.Add("Chinese Traditional(????)","zh-TW");      
slLanguage.Add("Kazakh","kk-KZ");
slLanguage.Add("Russian(???????)","ru-RU");
slLanguage.Add("Vietnamese(Vi?t)","vi-VN");
slLanguage.Add("English", "en-US");

如何按价值获得密钥？

例如:获取项目键"zh-CN"

Answer 1

如果要从值获取键,可以使用SortedList.IndexOfValue(object value)获取指定值的索引.然后,使用从我们刚刚收集的值索引SortedList.GetKey(int index)返回一个键object.

例

SortedList slLanguage = new SortedList(); //Initializes a new SortedList of name slLanguage
//Add the keys and their values to the list
slLanguage.Add("Bahasa", "id-ID");
slLanguage.Add("Chinese Simplified(????)", "zh-CN");
slLanguage.Add("Chinese Traditional(????)", "zh-TW");
slLanguage.Add("Kazakh", "kk-KZ");
slLanguage.Add("Russian(???????)", "ru-RU");
slLanguage.Add("Vietnamese(Vi?t)", "vi-VN");
slLanguage.Add("English", "en-US");
//
object returnedKey = slLanguage.GetKey(slLanguage.IndexOfValue("zh-CN")); //Gets the key from zh-CN as returnedKey of type object

谢谢,
我希望你觉得这很有帮助:)
