使用c#修改web.config的assemblies部分中的值

Question

我需要找出一种方法来为web.config文件中的程序集节添加CRUD (创建、读取、更新和删除)支持。

它可能看起来像这样

<system.web>
    <compilation defaultLanguage="c#" debug="true" batch="false" targetFramework="4.0">
        <assemblies>
            <add assembly="System.Xml.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
            <add assembly="System.Data.DataSetExtensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> 
        </assemblies>
    </compilation>
</system.web>

我试着从这样的东西开始

public bool AssemblyExist(string name)
{
    var webConfig = new ExeConfigurationFileMap { ExeConfigFilename = GlobalSettings.FullpathToRoot + "web.config" };
    var config = ConfigurationManager.OpenMappedExeConfiguration(webConfig, ConfigurationUserLevel.None);
    var assemblies = config.GetSection("system.web");

     // return true on match
    return assemblies.ElementInformation.Properties.Keys.Equals(name);
}

但它当然会失败。

因此，我想要的是一个示例，展示如何实际获取system.web > compilation > values部分中的值！

有什么建议吗？

Answer 1

有一个名为AssemblyInfo的数据类型，它的关键字！

private bool AssemblyExist(string fullName)
{
    var config = WebConfigurationManager.OpenWebConfiguration("~");
    var compilationSection = (CompilationSection)config.GetSection("system.web/compilation");

    return compilationSection.Assemblies.Cast<AssemblyInfo>().Any(assembly => assembly.Assembly == fullName);
}

或者如果在ubmraco中使用它

private bool AssemblyExist(string fullName)
{
    var webConfig = new ExeConfigurationFileMap { ExeConfigFilename = GlobalSettings.FullpathToRoot + "web.config" };
    var config = ConfigurationManager.OpenMappedExeConfiguration(webConfig, ConfigurationUserLevel.None);
    var compilationSection = (CompilationSection)config.GetSection("system.web/compilation");

    return compilationSection.Assemblies.Cast<AssemblyInfo>().Any(assembly => assembly.Assembly == fullName);
}

这样叫它

AssemblyExist("System.Xml.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089")

并添加程序集

private static void AddAssembly(string fullName)
{
    var config = WebConfigurationManager.OpenWebConfiguration("~");
    var compilationSection = (CompilationSection)config.GetSection("system.web/compilation");

    var myAssembly = new AssemblyInfo(fullName);
    compilationSection.Assemblies.Add(myAssembly);
    config.Save();
}

把它叫做

AddAssembly("System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35");
