写.exe.config文件最简单的方式是什么? 樓主是不是想通過修改.exe.config裡面的屬性來改窗體上空件的屬性? 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 我的想法是,我的某个值是从.exe.config中读取的。我在程序中有可能修改该值。并且我想保存它,我在下次运行时读取。 using System;using System.Collections;using System.ComponentModel;using System.Data;using System.Drawing;using System.Web;using System.Web.SessionState;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.HtmlControls;using System.Xml ;namespace WebApplication1{/// <summary>/// Summary description for WebForm1./// </summary>public class WebForm1 : System.Web.UI.Page{protected System.Web.UI.WebControls.TextBox TextBox1;protected System.Web.UI.WebControls.DropDownList DropDownList1;protected System.Web.UI.WebControls.Button Button1;public WebForm1(){Page.Init += new System.EventHandler(Page_Init);}private void Page_Load(object sender, System.EventArgs e){if(!Page.IsPostBack){//打开某文件(假设WEB。CONFIG在根目录中)string filename=Server.MapPath("/") + @"\web.config";XmlDocument xmldoc= new XmlDocument();xmldoc.Load(filename);XmlNodeList topM=xmldoc.DocumentElement.ChildNodes;foreach(XmlElement element in topM){if(element.Name.ToLower()=="appsettings"){XmlNodeList _node=element.ChildNodes;if ( _node.Count >0 ){DropDownList1.Items.Clear();foreach(XmlElement el in _node){DropDownList1.Items.Add(el.Attributes["key"].InnerXml);}}}}}}private void Page_Init(object sender, EventArgs e){InitializeComponent();}#region Web Form Designer generated code/// <summary>/// Required method for Designer support - do not modify/// the contents of this method with the code editor./// </summary>private void InitializeComponent(){ this.Button1.Click += new System.EventHandler(this.Button1_Click);this.Load += new System.EventHandler(this.Page_Load);}#endregionprivate void Button1_Click(object sender, System.EventArgs e){string filename=Server.MapPath("/") + @"\web.config";XmlDocument xmldoc= new XmlDocument();xmldoc.Load(filename);XmlNodeList topM=xmldoc.DocumentElement.ChildNodes;foreach(XmlElement element in topM){if(element.Name.ToLower()=="appsettings"){XmlNodeList _node=element.ChildNodes;if ( _node.Count >0 ) {foreach(XmlElement el in _node){if(el.Attributes["key"].InnerXml.ToLower()==this.DropDownList1.SelectedItem.Value.ToLower()){el.Attributes["value"].Value=this.TextBox1.Text;}}}}}xmldoc.Save(filename);}}这是在程序中动态的修改CONFIG文件一个程序!!没有给前台程序!!! 请问 宿主 二字是什么意思??? C#如何获得文件现在状态 如何实现这个泛型方法? 我的VS2005代码编辑器怎么不能按回车、退格、TAB、Fn等控制键了??急救啊!! XP中有没有哪个文件存放48*48的图标? 哪位有Windows窗体上模拟LED数字显示的控件? C#打印功能如何实现? 文本替换[菜鸟] Rundll32.exe 请教高手,怎样为集合添加事件? 对象的清除(用过VB的朋友来看看) 高分求救!
我在程序中有可能修改该值。并且我想保存它,我在下次运行时读取。
