enum Enum to dictionary dictionary

Method One:

Dictionary<int, string> mydic = new Dictionary<int, string> (); foreach (Enumname foo in enum.getvalues (typeof (Enumname))) {    mydic. ADD ((int) foo, foo. ToString ());}

Method Two:

var dict = enum.getvalues (typeof (Enumname))               . Cast<enumname> ()               . ToDictionary (t = = (int) T, t = = t.tostring ());

Method Three "key is Value,value is description (if not present description is name)":

<summary>///enumeration to dictionary collection///</summary>///<typeparam name= "T" > Enum class name </typeparam>///<param Name= "Keydefault" > Default key value </param>///<param name= "Valuedefault" > Default value Value </param>///< Returns> returns the generated dictionary collection </returns>public static dictionary<string, object> enumlistdic<t> (string Keydefault, String valuedefault = "") {dictionary<string, object> dicenum = new dictionary<string, object> (    );    Type enumtype = typeof (T);    if (!enumtype.isenum) {return dicenum; } if (!string.    IsNullOrEmpty (Keydefault))//Determine whether to add the default option {Dicenum.add (Keydefault, Valuedefault); } string[] Fieldstrs = Enum.getnames (enumtype); Gets an enumeration field array of foreach (var item in fieldstrs) {string description = string.        Empty;        var field = Enumtype.getfield (item); object[] arr = field. GetCustomAttributes (typeof (DescriptionAttribute), true); Gets an array of attribute fields if (arr! = null && arr.      Length > 0)  {Description = ((DescriptionAttribute) arr[0]).   Description;  Property Description} else {description = Item;  Description does not exist fetch field name} dicenum.add (description, (int) enum.parse (enumtype, item)); The reason for not using the enumerated value value as the Dictionary key value from the enumeration example can be seen, in fact, this should be judged that his value does not exist, the default field name} return dicenum;}
