如何编辑应用程序配置设置？ App.config最好的方法去？

For my project I have settings that I added through the Settings in the project properties.

对于我的项目,我有通过项目属性中的“设置”添加的设置。

I quickly discovered that editing the app.config file directly seems to no really update the settings value. Seems I have to view the project properties when I make a change and then recompile.

我很快发现直接编辑app.config文件似乎没有真正更新设置值。似乎我在进行更改然后重新编译时必须查看项目属性。

I'm wondering ... what is the best and easiest way to handle customizable settings for a project -- thought this would be a no-brainer with how .Net handles it ... shame on me.

我想知道......处理项目的可自定义设置的最佳和最简单的方法是什么 - 认为这对于.Net如何处理它是一个明智的选择......让我感到羞耻。
Is it possible to use one of the settings, AppSettings, ApplicationSettings, or UserSettings to handle this?

是否可以使用其中一个设置,AppSettings,ApplicationSettings或UserSettings来处理这个问题?

Is it better to just write my settings to custom config file and handle things myself?

将我的设置写入自定义配置文件并自行处理是否更好?

Right now ... I am looking for the quickest solution!

现在......我正在寻找最快的解决方案!

My environment is C#, .Net 3.5 and Visual Studio 2008.

I am trying to do the following:

我正在尝试执行以下操作:

    protected override void Save()
    {
        Properties.Settings.Default.EmailDisplayName = this.ddEmailDisplayName.Text;
        Properties.Settings.Default.Save();
    }

Gives me a read-only error when I compile.

编译时给我一个只读错误。

This is silly ... and I think I am going to have to apologize for wasting everyone's time! But it looks like I just need to set the scope to User instead of Application and I can the write the new value.

这很愚蠢......我想我不得不为浪费每个人的时间而道歉!但看起来我只需要将范围设置为User而不是Application,我可以编写新值。

#2

 System.Configuration.Configuration config =ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

        config.AppSettings.Settings["oldPlace"].Value = "3";     
        config.Save(ConfigurationSaveMode.Modified);
        ConfigurationManager.RefreshSection("appSettings");

Try with this code , is easy.

尝试使用此代码很容易。

I had the same problem until I realized I was running the app in debug mode, therefore my new appSetting's key was being written to the [applicationName].vshost.exe.config file.

我遇到了同样的问题,直到我意识到我在调试模式下运行应用程序,因此我的新appSetting的密钥被写入[applicationName] .vshost.exe.config文件。

And this vshost.exe.config file does NOT retain any new keys once the app is closed -- it reverts back to the [applicationName].exe.config file's contents.

此应用程序关闭后,此vshost.exe.config文件不会保留任何新密钥 - 它将恢复为[applicationName] .exe.config文件的内容。

I tested it outside of the debugger, and the various methods here and elsewhere to add a configuration appSetting key work fine. The new key is added to:[applicationName].exe.config.

我在调试器之外测试了它,并在这里和其他地方添加配置appSetting键的各种方法工作正常。新密钥将添加到:[applicationName] .exe.config。

I also tried to resolved this need and I have now a nice pretty ConsoleApplication, which i want to share: (App.config)

Not sure if this is what you are after, but you can update and save the setting from the app:

不确定这是否是您所追求的,但您可以从应用程序更新并保存设置:

ConsoleApplication1.Properties.Settings.Default.StringSetting = "test"; ConsoleApplication1.Properties.Settings.Default.Save();

ConsoleApplication1.Properties.Settings.Default.StringSetting =“test”; ConsoleApplication1.Properties.Settings.Default.Save();

#6

How are you referencing the Settings class in your code? Are you using the default instance or creating a new Settings object? I believe that the default instance uses the designer generated value which is re-read from the configuration file only when the properties are opened. If you create a new object, I believe that the value is read directly from the configuration file itself rather from the designer-generated attribute, unless the setting doesn't exist in the app.config file.

你是如何在代码中引用Settings类的?您使用默认实例还是创建新的Settings对象?我相信默认实例使用设计器生成的值,只有在打开属性时才会从配置文件中重新读取该值。如果您创建一个新对象,我相信该值直接从配置文件本身读取,而不是从设计器生成的属性读取,除非app.config文件中不存在该设置。

Typically my settings will be in a library rather than directly in the application. I set valid defaults in the properties file. I can then override these by adding the appropriate config section (retrieved and modified from the library app.config file) in the application's configuration (either web.config or app.config, as appropriate).

通常,我的设置将在库中,而不是直接在应用程序中。我在属性文件中设置了有效的默认值。然后我可以通过在应用程序的配置中添加适当的配置部分(从库app.config文件中检索和修改)来覆盖它们(如果适用,可以是web.config或app.config)。

Using:

 Settings configuration = new Settings();
 string mySetting = configuration.MySetting;

instead of:

 string mySetting = Settings.Default.MySetting;

is the key for me.

对我来说是关键。

EDIT: My mistake. I misunderstood the purpose of the original question.

编辑:我的错。我误解了原问题的目的。

ORIGINAL TEXT:

We often setup our settings directly in the app.config file, but usually this is for our custom settings.

我们经常直接在app.config文件中设置我们的设置,但通常这是我们的自定义设置。

Example app.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <section name="MySection" type="System.Configuration.NameValueFileSectionHandler, System, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    </configSections>
    <connectionStrings>
        <add name="Default" connectionString="server=MyServer;database=MyDatabase;uid=MyDBUser;password=MyDBPassword;connection timeout=20" providerName="System.Data.SqlClient" />
    </connectionStrings>
    <MySection>
        <add key="RootPath" value="C:\MyDirectory\MyRootFolder" /> <!-- Path to the root folder. -->
        <add key="SubDirectory" value="MySubDirectory" /> <!-- Name of the sub-directory. -->
        <add key="DoStuff" value="false" /> <!-- Specify if we should do stuff -->
    </MySection>
</configuration>

#8

Try this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>

  <configSections>
   <!--- ->
  </configSections>

  <userSettings>
   <Properties.Settings>
      <setting name="MainFormSize" serializeAs="String">
        <value>
1022, 732</value>
      </setting>
   <Properties.Settings>
  </userSettings>

  <appSettings>
    <add key="TrilWareMode" value="-1" />
    <add key="OptionsPortNumber" value="1107" />
  </appSettings>

</configuration>

Reading values from App.Config File:

从App.Config文件中读取值:

//This method will read the value of the OptionsPortNumber in the
//above app.config file.
private int LoadConfigData ()
    {
        System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
        // AppDomain.CurrentDomain.SetupInformation.ConfigurationFile
        // points to the config file.   
        doc.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
        int smartRefreshPortNumber = 0;
        foreach (XmlNode node in doc.ChildNodes.Item(1))
        {
        //Searching for the node “”
            if (node.LocalName == "appSettings")
            {
                 smartPortNumber =Convert.ToInt32(node.ChildNodes.Item(1).Attributes[1].Value);
            }
        }
        Return smartPortNumber;
    }

Updating the value in the App.config:

更新App.config中的值:

//This method will read the value of the OptionsPortNumber in the
//above app.config file.
private void UpdateConfigData()
    {
        System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
        doc.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);


        //Looping through all nodes.
        foreach (XmlNode node in doc.ChildNodes.Item(1))
        {
        //Searching for the node “”
            if (node.LocalName == "appSettings")
            {
                if (!dynamicRefreshCheckBox.Checked)
                {
                    node.ChildNodes.Item(1).Attributes[1].Value = this.portNumberTextBox.Text;
                }
                else
                {
                    node.ChildNodes.Item(1).Attributes[1].Value = Convert.ToString(0);
                }
            }
        }
        //Saving the Updated values in App.config File.Here updating the config
        //file in the same path.
        doc.Save(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
    }
