在C#中,有多種方法可以幫助您簡化代碼。以下是一些建議:
var numbers = new List<int> { 1, 2, 3, 4, 5 };
var evenNumbers = numbers.Where(n => n % 2 == 0);
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
public static class StringExtensions
{
public static string ToTitleCase(this string input)
{
return input.Split(' ')
.Select(word => char.ToUpper(word[0]) + word.Substring(1).ToLower())
.Aggregate((x, y) => x + " " + y);
}
}
public async Task<string> GetWebContentAsync(string url)
{
using (var client = new HttpClient())
{
var response = await client.GetAsync(url);
var content = await response.Content.ReadAsStringAsync();
return content;
}
}
public interface IMessageService
{
Task SendAsync(string message);
}
public class EmailService : IMessageService
{
public Task SendAsync(string message)
{
// 發送電子郵件的實現
}
}
public class MessageController : Controller
{
private readonly IMessageService _messageService;
public MessageController(IMessageService messageService)
{
_messageService = messageService;
}
public async Task<IActionResult> Send(string message)
{
await _messageService.SendAsync(message);
return Ok();
}
}
public static class Shape
{
public static double Area(Circle circle)
{
return Math.PI * circle.Radius * circle.Radius;
}
public static double Area(Rectangle rectangle)
{
return rectangle.Width * rectangle.Height;
}
}
遵循這些建議,您將能夠編寫更簡潔、易讀的C#代碼。
