本文通过一个ASP.NET示例介绍了如何在C#中使用KeyValuePair来遍历字典，并展示了具体的实现代码及运行结果。

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

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

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

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));
}
}
}

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)); } } }

执行結果:
