[Dotnet][C#]Dictionary的foreach使用KeyValuePair

foreach (KeyValuePair<int, string> kvp in myDictionary) {...}

看到這句就大概可以猜出來了,就是用KeyValuePair,用範例介紹如何使用..

asp.net(c#)
TestKeyValuePair.aspx.cs

  1. using System;  
  2. using System.Data;  
  3. using System.Configuration;  
  4. using System.Collections;  
  5. using System.Web;  
  6. using System.Web.Security;  
  7. using System.Web.UI;  
  8. using System.Web.UI.WebControls;  
  9. using System.Web.UI.WebControls.WebParts;  
  10. using System.Web.UI.HtmlControls;  
  11. using System.Collections.Generic;  
  12.   
  13. public partial class TestKeyValuePair : System.Web.UI.Page  
  14. {  
  15.     protected void Page_Load(object sender, EventArgs e)  
  16.      {  
  17.          Dictionary<string, string> dic = new Dictionary<string, string>();  
  18.   
  19.          dic.Add("Name", "puma");  
  20.          dic.Add("Blog", "F6 Team");  
  21.          dic.Add("Group", "Dotblogs");  
  22.   
  23.         foreach (KeyValuePair<string, string> item in dic)  
  24.          {  
  25.              Response.Write(string.Format("{0} : {1}<br/" + ">", item.Key, item.Value));  
  26.          }  
  27.   
  28.      }  
  29. }  

 

 

using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Collections.Generic; public partial class TestKeyValuePair : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Dictionary<string, string> dic = new Dictionary<string, string>(); dic.Add("Name", "puma"); dic.Add("Blog", "F6 Team"); dic.Add("Group", "Dotblogs"); foreach (KeyValuePair<string, string> item in dic) { Response.Write(string.Format("{0} : {1}<br/" + ">", item.Key, item.Value)); } } }
