C# 中Web.config文件的读取与写入
View Code
1 //修改栏目订单的颜色
2 private void btnfunColor_Click(object sender, EventArgs e)
3 {
4 ColorDialog fontcolor = new ColorDialog();
5 if (fontcolor.ShowDialog() == DialogResult.OK)
6 {
7 strColors[Convert.ToInt32(cmbFunInfo.SelectedValue)] = fontcolor.Color;
8 int argb = fontcolor.Color.ToArgb();
9 Color.FromArgb(argb);
10 //写入文件
11 Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
12 AppSettingsSection app = config.AppSettings;
13 app.Settings.Add(cmbFunInfo.SelectedValue.ToString(), argb.ToString());
14 config.Save(ConfigurationSaveMode.Modified);
15 }
16 }
然后读取指定的key值
View Code
1 /// <summary>
2 /// 读取指定key的值
3 /// </summary>
4 /// <param name="key"></param>
5 /// <returns></returns>
6 public static string GetValue(string key)
7 {
8 System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
9
10 if (config.AppSettings.Settings[key] == null)
11 return "";
12 else
13 return config.AppSettings.Settings[key].Value;
14 }
然后循环读取每个栏目所对应的数据
View Code
1 //设定颜色
2 private void SetDGVfontColors()
3 {
4 try
5 {
6 //循环遍历设定行的颜色
7 for (int i = 0; i < dgvOrders.Rows.Count; i++)
