C＃列挙型TryParse（）メソッド

TryParse（）メソッドは、1つ以上の列挙型定数の文字列表現を同等の列挙型オブジェクトに変換します。

まず、列挙型を設定します。

enum Vehicle { Bus = 2, Truck = 4, Car = 10 };

次に、文字列配列を宣言して、いくつかの値を設定しましょう。

string[] VehicleList = { "2", "3", "4", "bus", "Truck", "CAR" };

次に、Enum TryParse（）メソッドを使用して値を解析します。

例

using System;
public class Demo {
   enum Vehicle { Bus = 2, Truck = 4, Car = 10 };
   public static void Main() {
      string[] VehicleList = { "2", "3", "4", "bus", "Truck", "CAR" };
      foreach (string val in VehicleList) {
         Vehicle vehicle;
         if (Enum.TryParse(val, true, out vehicle))
         if (Enum.IsDefined(typeof(Vehicle), vehicle) | vehicle.ToString().Contains(","))
         Console.WriteLine("Converted '{0}' to {1}", val, vehicle.ToString());
         else
         Console.WriteLine("{0} is not a value of the enum", val);
         else
         Console.WriteLine("{0} is not a member of the enum", val);
      }
   }
}
