我想打电话给我设置和放大器中的自定义操作;部署计划来更新我的应用程序在app.config中的一些项目。我已经结束了在通常的方式自定义配置部分，例如：

I'm trying to call a custom action within my Setup & Deployment project to update some items within the app.config on my app. I've wrapped up the custom config section in the usual way, e.g.:

[ConfigurationProperty("serviceProvider", IsRequired = true)]
public string ServiceProvider
{
    get { return (string)base["serviceProvider"]; }
    set { base["dataProviderFactory"] = value; }
}

我给自己定的安装，之后base.Install（stateSaver）安装节期间，被称为自定义操作。在code是：

I've set the custom action to be called during the Install section of installation just after base.Install(stateSaver). The code is:

string exePath = string.Format("{0} MyApp.exe", Context.Parameters["DP_TargetDir"]);
SysConfig.Configuration config = ConfigurationManager.OpenExeConfiguration(exePath);
Configuration. MyApp section = Configuration.MyApp)config.GetSection("MyApp");

当我运行它，我得到这个错误：

When I run this, I get this error:

System.Configuration.ConfigurationErrorsException：出错创造MyApp的配置节处理程序：无法加载文件或程序集MyCompany的。 MyApp.Configuration或它的某一个依赖。该系统找不到指定的文件。 （C：\ Program Files文件\ MyCompany的\ MyApp的\ MyApp.exe.config 5号线）---> System.IO.FileNotFoundException：找不到无法加载文件或程序集MyCompany.MyApp.Configuration或它的某一个依赖。该系统找不到指定的文件。

System.Configuration.ConfigurationErrorsException: An error occurred creating the configuration section handler for MyApp: Could not load file or assembly 'MyCompany. MyApp.Configuration' or one of its dependencies. The system cannot find the file specified. (C:\Program Files\MyCompany\MyApp\MyApp.exe.config line 5) ---> System.IO.FileNotFoundException: Could not load file or assembly 'MyCompany.MyApp.Configuration' or one of its dependencies. The system cannot find the file specified.

5号线的配置为：

<section name="MyApp"
    type="MyCompany.MyApp.Configuration.MyApp, MyCompany.MyApp.Configuration"
    requirePermission="false" />

该类库的安装程序code（这是该库中的唯一一类）有一个参考配置组件。

The class library with the installer code (that being the only class in that library) has a reference to the config assembly.

有什么真的很明显，我在这里失踪？为什么没有被发现裁判的配置我不能工作了。

Is there something really obvious that I'm missing here? I can't work out why the ref to the config isn't being found.

任何帮助/建议将是非常美联社preciated。

Any help/suggestions would be very much appreciated.

推荐答案

我设法找到MSDN上的一些code，它提供了一个工作（虽然黑客攻击）的方式来做到这一点。链接是在这里：ConfigurationManager,自定义的配置，和installutil /路径搜索问题。

I managed to find some code on MSDN that provides a working (albeit hacked) way to do this. Link is here: ConfigurationManager, custom config, and installutil / path searching problem.

会不会发现它，如果不是能与帮助调试的建议，以便得益于双方你。

Wouldn't have found it if not for being able to debug with help from suggestions so thanks to both of you for that.

作为参考，我的最终安装code是：

For reference, my final install code is:

public override void Install(IDictionary stateSaver)
{
    base.Install(stateSaver);

    string targetDirectory = Context.Parameters["DP_TargetDir"];
    stateSaver.Add("TargetDir", targetDirectory);

    string exePath = Path.Combine(targetDirectory, "MyApp.exe");

    System.Diagnostics.Debugger.Break();

    ResolveEventHandler tempResolveEventHandler =
        (sender, args) =>
            {
                string simpleName = new AssemblyName(args.Name).Name;
                string path = Path.Combine(targetDirectory, simpleName + ".dll");
                return File.Exists(path)
                    ? Assembly.LoadFrom(path)
                    : null;
            };

    try
    {
        // hook up asm resolve handler  
        AppDomain.CurrentDomain.AssemblyResolve += tempResolveEventHandler;

        System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(exePath);
        Configuration.MyApp section = (Configuration.MyApp) config.Sections["MyApp"];

        if (section != null)
        {
            // "ApplicationSettings.DefaultDatabasePath" is the custom config value I'm updating
            section.ApplicationSettings.DefaultDatabasePath = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
            config.Save();
        }
    }
    finally
    {
        // remove asm resolve handler.  
        AppDomain.CurrentDomain.AssemblyResolve -= tempResolveEventHandler;
    }

}
