如何打印Dictionary <string,MyClass>

Question

打印字典的最佳方法是什么,我创建了Currency类,如下所示

class Currency{
  public string currency_code { get; set; }
  public float unit { get; set; }
  public string currency_name { get; set; }
  public string currency_isim { get; set; }
  public float forex_buying { get; set; }
  public float forex_selling { get; set; }
  public float banknote_buying { get; set; }
  public float banknote_selling { get; set; }
}

有没有办法自动打印对象？

我想尽可能打印出来

Dictionary<string, Currency> dict = new Dictionary<string, Currency>();
.....
.....
add data to dict properly
..... 
.....
dict.print();

我希望它返回一个包含该对象的所有数据的正确字符串.我怎样才能做到这一点？

Answer 1

public class Currency
{
  ...
  public override string ToString()
  {
    return String.Format("Currency Code: {0}\nUnit:{1}...",...);
  }
}

foreach (string key in dict.Keys)
{
  Console.WriteLine("Key: {0}\nValue{1}", key, dict[key].ToString());
}

覆盖ToString,遍历所有键/值,然后打印.
