C#之App.Config文件操作的实现
作者：*Major*-莙工科技有限公司
AppConfigHelper提供了一种方便的方式来读取、添加、修改和删除应用程序配置文件中的配置项,本文主要介绍了C#之App.Config文件操作的实现,感兴趣的可以了解一下
一 AppConfigHelper
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Helper
{
/// <summary>
/// 操作配置文件(App.config)
/// </summary>
public class AppConfigHelper
{
/// <summary>
/// 输入Key的值，返回配置的值
/// </summary>
/// <param name="KeyName"></param>
/// <returns></returns>
public string ReadConfig(string KeyName)
{
Configuration cfa = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
return cfa.AppSettings.Settings[KeyName].Value;
}
/// <summary>
/// 根据配置的名称，查询独立的数据,读取app.config
/// </summary>
/// <param name="ProName"></param>
/// <param name="KeyName"></param>
/// <returns></returns>
public string ReadConfig(string ProName, string KeyName)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var mySection = config.GetSection(ProName) as CommonSection;
foreach (CommonSection.CommonKeyValueSetting add in mySection.KeyValues)
{
if (add.Key == KeyName)
{
return add.Value;
}
}
return null;
}
/// <summary>
/// 增加配置文件
/// </summary>
/// <param name="KeyName"></param>
/// <param name="Value"></param>
public void AddConfig(string KeyName, string Value)
{
Configuration cfa = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
cfa.AppSettings.Settings.Add(KeyName, Value);
cfa.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");
}
/// <summary>
/// 根据配置的名称，查询独立的数据,并添加独立的内容
/// </summary>
/// <param name="ProName"></param>
/// <param name="KeyName"></param>
/// <param name="Value"></param>
/// <returns></returns>
public void AddConfig(string ProName, string KeyName, string Value)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var mySection = config.GetSection(ProName) as CommonSection;
mySection.KeyValues.Add(new CommonSection.CommonKeyValueSetting() { Key = KeyName, Value = Value });
config.Save();
ConfigurationManager.RefreshSection(ProName); //刷新
}
/// <summary>
/// 删除配置文件
/// </summary>
/// <param name="KeyName"></param>
public void DeleteConfig(string KeyName)
{
Configuration cfa = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
cfa.AppSettings.Settings.Remove(KeyName);
cfa.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");
}
/// <summary>
/// 修改配置文件数据
/// </summary>
/// <param name="KeyName"></param>
/// <param name="Value"></param>
public void WriteConfig(string KeyName, string Value)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.AppSettings.Settings[KeyName].Value = Value;
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");
}
/// <summary>
/// 根据配置的名称，查询独立的数据,并修改内容
/// </summary>
/// <param name="ProName"></param>
/// <param name="KeyName"></param>
/// <param name="Value"></param>
/// <returns></returns>
public void WriteConfig(string ProName, string KeyName, string Value)
{
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var mySection = config.GetSection(ProName) as CommonSection;
mySection.KeyValues.Remove(KeyName);
mySection.KeyValues.Add(new CommonSection.CommonKeyValueSetting() { Key = KeyName, Value = Value });
config.Save();
ConfigurationManager.RefreshSection(ProName); //刷新
}
}
/// <summary>
/// 配置节点基类
/// </summary>
public class CommonSection : ConfigurationSection
{
private static ConfigurationProperty s_property =
new ConfigurationProperty(string.Empty, typeof(CommonKeyValueCollection), null, ConfigurationPropertyOptions.IsDefaultCollection);
[ConfigurationProperty("", Options = ConfigurationPropertyOptions.IsDefaultCollection)]
public CommonKeyValueCollection KeyValues
{
get
{
return (CommonKeyValueCollection)base[s_property];
}
}
/// <summary>
/// 自定义一个集合
/// </summary>
[ConfigurationCollection(typeof(CommonKeyValueSetting))]
public class CommonKeyValueCollection : ConfigurationElementCollection
{
public CommonKeyValueCollection() : base(StringComparer.OrdinalIgnoreCase)
{
}
new public CommonKeyValueSetting this[string name]
{
get { return (CommonKeyValueSetting)base.BaseGet(name); }
set { base[name] = value; }
}
protected override ConfigurationElement CreateNewElement()
{
return new CommonKeyValueSetting();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((CommonKeyValueSetting)element).Key;
}
public void Add(CommonKeyValueSetting setting)
{
this.BaseAdd(setting);
}
public void Clear()
{
base.BaseClear();
}
public void Remove(string name)
{
base.BaseRemove(name);
}
}
/// <summary>
/// 集合中的每个元素
/// </summary>
public class CommonKeyValueSetting : ConfigurationElement
{
/// <summary>
/// 键
/// </summary>
[ConfigurationProperty("key", IsRequired = true)]
public string Key
{
get { return this["key"].ToString(); }
set { this["key"] = value; }
}
/// <summary>
/// 值
/// </summary>
[ConfigurationProperty("value", IsRequired = true)]
public string Value
{
get { return this["value"].ToString(); }
set { this["value"] = value; }
}
}
}
}
二 读取标准 appSettings
添加appSettings
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.8" />
</startup>
<appSettings>
<add key="Width" value="100"/>
<add key="Height" value="200"/>
<add key="Area" value="99"/>
</appSettings>
</configuration>
读取appSettings
// 全局变量 AppConfigHelper config = new AppConfigHelper();
string h = config.ReadConfig("Height");
MessageBox.Show(h.ToString());
三 添加配置 appSettings
config.AddConfig("XXXX", "vvvv");
MessageBox.Show("添加成功！！");
string va = config.ReadConfig("XXXX");
四 修改标准 appSettings
config.WriteConfig("Height", "7777");
MessageBox.Show("修改成功！！");
五 删除配置 appSettings
config.DeleteConfig("Height");
MessageBox.Show("删除成功！！");
