打印字典值的简单方法？

Question

我有下面的代码：

static void Main(string[] args) 
{ 
    // Add 5 Employees to a Dictionary. 
    var Employees = new Dictionary<int, Employee>(); 
    Employees.Add(1, new Employee(1, "John")); 
    Employees.Add(2, new Employee(2, "Henry")); 
    Employees.Add(3, new Employee(3, "Jason")); 
    Employees.Add(4, new Employee(4, "Ron")); 
    Employees.Add(5, new Employee(5, "Yan")); 
} 

有一种简单的方法来打印一个简单的方法在字典的值与Java？举例来说，我希望能够打印出类似这样：

员工与关键1：ID = 1，名称=约翰

员工与关键2：ID = 2，名称=亨利

..等。

谢谢。

对不起，我习惯了Java！

Answer 1

您可以使用foreach语句：

foreach(var pair in Employees) 
{ 
    Console.WriteLine($"Employee with key {pair.Key}: Id={pair.Value.Id} Name={pair.Value.Name}"); 
} 

Answer 2

您可以定义一个IDictionary参考，并使其指向Dictionary对象

IDictionary<int, Employee> employees = new Dictionary<int,Employee>(); 
employees.Add(1, new Employee(1, "John")); 
//add the rest of the employees 

通过字典来循环，您可以使用

foreach(KeyValuePair<int, Employee> entry in employees) 
{ 
    Console.WriteLine("Employee with key "+entry.Key+": Id="+entry.Value.GetId()+", Name= "+entry.Value.GetName()); 
} 

这类似于Java的HashMap<>。

Answer 3

您可以使用foreach循环打印的字典里面所有的值。

foreach(var employe in Employees) { 
    Console.WriteLine(string.Format("Employee with key {0}: Id={1}, Name= {2}",employe.Key, employe.Value.Id, employe.Value.Name)); 
} 

Answer 4

尝试使用foreach：

foreach (var res in Employees) 
{ 
    Console.WriteLine("Employee with key {0}: ID = {1}, Name = {2}", res.Key, res.Value.Id, res.Value.Name); 
} 

，或者简单地使用LINQ：

var output = Employees.Select(res => "Employee with key " + res.Key + ": ID = " + res.Value.Id + ", Name = " + res.Value.Name); 

Answer 5

var items = Employees.Select(kvp => string.Format("Employee with key {0} : Id={1}, Name={2}", kvp.Key, kvp.Value.Id, kvp.Value.Name); 

var text = string.Join(Environment.NewLine, items);
