C＃ - 字典<key, value>列出<T>

Question

我要地圖我Dictionary<int, string>到List<Customer>其中Customer有兩個屬性Id和Name。現在我想將字典的整數Key映射到List<Customer>[i].Key屬性和Value的字典到List<Customer>[i].Name迭代。

需要幫助。

Answer 1

var dict = new Dictionary<int, string>(); // populate this with your data 

var list = dict.Select(pair => new Customer { Id = pair.Key, Name = pair.Value }).ToList(); 

您還可以使用適當的Customer構造函數（如果可用）而不是示例屬性setter語法。

Answer 2

你可以這樣做：

List<Customer> list = theDictionary 
         .Select(e => new Customer { Id = e.Key, Name = e.Value }) 
         .ToList(); 

Answer 3

var myList = (from d in myDictionary 
      select new Customer { 
       Key = d.Key, 
       Name = d.Value 
      }).ToList(); 

Answer 4

鑑於myDictionary填充和myList IST目標列表：

myDictionary.ToList() 
      .ForEach(x => 
        myList.Add(new Customer() {Id = x.Key, Name = x.Value}) 
        );
