属性方法中并没有包含此功能,因此需要自己自定义一个方法:
string regionName = ""; if (ControlForm.swichLanguage.Contains("EN")) { var regionName1 = en_Resx.Where(q => q.Value == ((Button)sender).Text).Select(q => q.Key); IEnumerator enumerator = regionName1.GetEnumerator(); while (enumerator.MoveNext()) { regionName = (string)enumerator.Current; } } else { regionName = ((Button)sender).Text; }
其它方法查看(如下):
private void GetDicKeyByValue() { Dictionary<string, string> dic = new Dictionary<string, string>(); dic.Add("1", "1"); dic.Add("2", "2"); dic.Add("3", "2"); //foreach KeyValuePair traversing foreach (KeyValuePair<string, string> kvp in dic) { if (kvp.Value.Equals("2")) { //...... kvp.Key; } } //foreach dic.Keys foreach (string key in dic.Keys) { if (dic[key].Equals("2")) { //...... key } } //Linq var keys = dic.Where(q => q.Value == "2").Select(q => q.Key); //get all keys List<string> keyList = (from q in dic where q.Value == "2" select q.Key).ToList<string>(); //get all keys var firstKey = dic.FirstOrDefault(q => q.Value == "2").Key; //get first key }
