在.NET
2.0中对配置文件app.config文件的读写变得相当简单了,在创建一个新的项目后VS2005会自动生成配置文件(Settings.settings)及app.config,如没有请:右键项目--属性--设置里添加一条配置信息(如下图),VS2005将自动生成这些文件:
Settings.Designer.cs
VS2005基本都完成了,现在我们读写时就只需要写几行代码就行了:
Settings.Designer.cs
namespace WindowsApplication1.Properties
{
internal sealed partial class Settings :
global::System.Configuration.ApplicationSettingsBase
{
private static Settings defaultInstance = ((Settings)
(global::System.Configuration.ApplicationSettingsBase.Synchronized(
new Settings())));
public static Settings Default
{
get { return defaultInstance; }
}
[global::System.Configuration.UserScopedSettingAttribute()]
[global::System.Configuration.DefaultSettingValueAttribute("Form1")]
public string testSetting
{
get { return ((string)(this["testSetting"])); }
set { this["testSetting"] = value; }
}
}
}
{
internal sealed partial class Settings :
global::System.Configuration.ApplicationSettingsBase
{
private static Settings defaultInstance = ((Settings)
(global::System.Configuration.ApplicationSettingsBase.Synchronized(
new Settings())));
public static Settings Default
{
get { return defaultInstance; }
}
[global::System.Configuration.UserScopedSettingAttribute()]
[global::System.Configuration.DefaultSettingValueAttribute("Form1")]
public string testSetting
{
get { return ((string)(this["testSetting"])); }
set { this["testSetting"] = value; }
}
}
}
VS2005基本都完成了,现在我们读写时就只需要写几行代码就行了:
Properties.Settings config = Properties.Settings.Default;
//读取
string str = config.testSetting;
//写入
config.testSetting = "test value";
config.Save();
//读取
string str = config.testSetting;
//写入
config.testSetting = "test value";
config.Save();
