C# Enum TryParse() 方法
csharpprogrammingserver side programming更新于 2025/9/14 4:46:00
TryParse() 方法将一个或多个枚举常量的字符串表示转换为等效的枚举对象。
首先，设置一个枚举。
enum Vehicle { Bus = 2, Truck = 4, Car = 10 };
现在，让我们声明一个字符串数组并设置一些值。
string[] VehicleList = { "2", "3", "4", "bus", "Truck", "CAR" };
现在使用 Enum TryParse() 方法相应地解析值。
示例
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);
}
}
}
输出
Converted '2' to Bus 3 is not a value of the enum Converted '4' to Truck Converted 'bus' to Bus Converted 'Truck' to Truck Converted 'CAR' to Car
