在安装过程中更改的App.config

本文介绍了在安装过程中更改的App.config的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有这样的设置的XML文件

 <？xml version =1.0encoding =utf- 8→> 
< configuration> 
< configSections> 
< sectionGroup name =applicationSettingstype =System.Configuration.ApplicationSettingsGroup，System，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089> 
< section name =UpdateReportService.Properties.Settingstype =System.Configuration.ClientSettingsSection，System，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089requirePermission =false/& 
< / sectionGroup> 
< / configSections> 
< applicationSettings> 
< UpdateReportService.Properties.Settings> 
< setting name =PathserializeAs =String> 
< value> C：\1< / value> 
< / setting> 
< setting name =BranchserializeAs =String> 
< value> 200< / value> 
< / setting> 
< setting name =b204serializeAs =String> 
< value> 192.168.1.55< / value> 
< / setting> 
< setting name =b200serializeAs =String> 
< value> 192.168.0.83< / value> 
< / setting> 
< setting name =HourserializeAs =String> 
< value> 11< / value> 
< / setting> 
< /UpdateReportService.Properties.Settings> 
< / applicationSettings> 
< / configuration>

我想将一些值更改为用户在安装程序中键入的值。



我发现VB上的示例并尝试将其转换为c＃：

 命名空间InstallConfigurator 
 {
 [RunInstaller（true）] 
 public class SettingsClass：Installer 
 {
 public override void Install（System.Collections.IDictionary stateSaver）
 { 
配置config = ConfigurationManager.OpenExeConfiguration（Context.Parameters [TARGETDIR]。ToString（）+UpdateReportService.exe）; 
 
 ClientSettingsSection applicationSettingsSection =（ClientSettingsSection）config.SectionGroups [applicationSettings]。部分[UpdateReportService.Properties.Settings]; 
 
 SettingElement Elem = applicationSettingsSection.Settings [Branch]; 
 
 applicationSettingsSection.Settings.Remove（Elem）; 
 
 
 Elem.Value.ValueXml.InnerXml =30000; 
 applicationSettingsSection.Settings.Add（Elem）; 
 
 config.Save（ConfigurationSaveMode.Full）; 
} 
} 
}

但得到错误到其保护级别：

  SettingElement Elem = applicationSettingsSection.Settings [Branch];

因此，是否可能在c＃上访问App.config中的部分并更改它。 / p>

我已经用这种方式解决了问题：

 命名空间InstallConfigurator 
 {
 [RunInstaller（true）] 
 public class SettingsClass：Installer 
 {
 public override void Install（System.Collections.IDictionary stateSaver ）
 {
 string xml = Context.Parameters [TARGETDIR]。ToString（）+UpdateReportService.exe.config; 
 
 XmlDocument document = new XmlDocument（）; 
 document.Load（xml）; 
 XPathNavigator navigator = document.CreateNavigator（）; 
 XmlNamespaceManager ns = new XmlNamespaceManager（navigator.NameTable）; 
 
 foreach（导航器中的XPathNavigator导航器。选择（@/ configuration / applicationSettings / UpdateReportService.Properties.Settings / setting [@ name ='Branch'] / value））
 {
 nav.SetValue（Context.Parameters [BRANCH]。ToString（））; 
} 
 
 foreach（导航器中的XPathNavigator导航器。选择（@/ configuration / applicationSettings / UpdateReportService.Properties.Settings / setting [@ name ='Path'] / value））
 {
 nav.SetValue（Context.Parameters [PATH]。ToString（））; 
} 
 
 document.Save（xml）; 
} 
} 
}


解决方案>

在类似的项目中，我使用的方式略有不同：


  1. myapp.exe.config文件

  2. 而是运送包含占位符的myapp.exe.config.default文件，例如 {

  3. 在安装过程中，将myapp.exe.config.default作为字符串加载到内存中。

  4. 使用实际值替换占位符（例如，您的 30000 ）。

  5. 将替换的字符串写为实际文件myapp.exe.config。

  6. 奖励：在写入配置之前，检查是否存在任何现有的配置文件，并将其复制为备份以保留以前的版本。

这在我们的应用程序中运行起来非常顺利。


I have XML-file with settings like this

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
            <section name="UpdateReportService.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
        </sectionGroup>
    </configSections>
    <applicationSettings>
        <UpdateReportService.Properties.Settings>
            <setting name="Path" serializeAs="String">
                <value>C:\1</value>
            </setting>
            <setting name="Branch" serializeAs="String">
                <value>200</value>
            </setting>
            <setting name="b204" serializeAs="String">
                <value>192.168.1.55</value>
            </setting>
            <setting name="b200" serializeAs="String">
                <value>192.168.0.83</value>
            </setting>
            <setting name="Hour" serializeAs="String">
                <value>11</value>
            </setting>
        </UpdateReportService.Properties.Settings>
    </applicationSettings>
</configuration>

And I'd like to change some values to values typed by user during install program.

I find example on VB and try convert it to c#:

namespace InstallConfigurator
{
    [RunInstaller(true)]
    public class SettingsClass : Installer
    {
        public override void Install(System.Collections.IDictionary stateSaver)
        {
            Configuration config = ConfigurationManager.OpenExeConfiguration(Context.Parameters["TARGETDIR"].ToString() + "UpdateReportService.exe");

            ClientSettingsSection applicationSettingsSection = (ClientSettingsSection)config.SectionGroups["applicationSettings"].Sections["UpdateReportService.Properties.Settings"];

            SettingElement Elem = applicationSettingsSection.Settings["Branch"];

            applicationSettingsSection.Settings.Remove(Elem);


            Elem.Value.ValueXml.InnerXml = "30000";
            applicationSettingsSection.Settings.Add(Elem);

            config.Save(ConfigurationSaveMode.Full);
        }
    }
}

But get error "inaccessible due to its protection level" at this place:

SettingElement Elem = applicationSettingsSection.Settings["Branch"];

So, is it possible on c# to access to section in App.config and to change it.

i've solved problem this way:

namespace InstallConfigurator
{
    [RunInstaller(true)]
    public class SettingsClass : Installer
    {
        public override void Install(System.Collections.IDictionary stateSaver)
        {
            string xml = Context.Parameters["TARGETDIR"].ToString() + "UpdateReportService.exe.config";

            XmlDocument document = new XmlDocument();
            document.Load(xml);
            XPathNavigator navigator = document.CreateNavigator();
            XmlNamespaceManager ns = new XmlNamespaceManager(navigator.NameTable);

            foreach (XPathNavigator nav in navigator.Select(@"/configuration/applicationSettings/UpdateReportService.Properties.Settings/setting[@name='Branch']/value"))
            {
                nav.SetValue(Context.Parameters["BRANCH"].ToString());
            }

            foreach (XPathNavigator nav in navigator.Select(@"/configuration/applicationSettings/UpdateReportService.Properties.Settings/setting[@name='Path']/value"))
            {
                nav.SetValue(Context.Parameters["PATH"].ToString());
            }

            document.Save(xml);
        }
    }
}
解决方案

In a similar project, I'm doing it in a slightly different way:

  1. Ship your setup with no "myapp.exe.config" file.
  2. Instead, ship a "myapp.exe.config.default" file that contains placeholders like "{Branch}".
  3. During setup, load the "myapp.exe.config.default" as a string into memory.
  4. Replace the placeholders with the actual values (e.g. your "30000").
  5. Write the replaced string as the actual file "myapp.exe.config".
  6. Bonus: Before writing the config check whether any existing config file is present and copy it as a backup to keep the previous version.

This runs pretty smooth in our applications.
