سلام 😉 در این مطلب از وب سایت پروگرم 98 کد تبدیل به Dictionary با IEqualityComparer و متد ToDictionary در c#.net را آماده کردم. انشاالله که این کد سی شارپ براتون مفید باشد.
کد تبدیل به Dictionary با IEqualityComparer و متد ToDictionary در c#.net:
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
public class Employee2 {
public string id;
public string firstName;
public string lastName;
public static ArrayList GetEmployeesArrayList() {
ArrayList al = new ArrayList();
al.Add(new Employee2 { id = "1", firstName = "J", lastName = "R" });
al.Add(new Employee2 { id = "2", firstName = "W", lastName = "G" });
al.Add(new Employee2 { id = "3", firstName = "A", lastName = "H"});
al.Add(new Employee2 { id = "4", firstName = "D", lastName = "L" });
al.Add(new Employee2 { id = "101", firstName = "K", lastName = "F" });
return (al);
}
public static Employee2[] GetEmployeesArray() {
return ((Employee2[])GetEmployeesArrayList().ToArray(typeof(Employee2)));
}
}
public class MyStringifiedNumberComparer : IEqualityComparer<string> {
public bool Equals(string x, string y) {
return (Int32.Parse(x) == Int32.Parse(y));
}
public int GetHashCode(string obj) {
return Int32.Parse(obj).ToString().GetHashCode();
}
