如何通过.msi包修改machine.config

Question

我正在尝试创建一个将部署.NET托管数据提供程序的安装程序.为了使数据提供程序在应用程序下拉列表中显示为提供程序,我必须在machine.config的部分中添加提供程序:

<system.data>
    <DbProviderFactories>
      <add name="My Data Provider" 
           invariant="Sample.MyDataProvider" 
           description="My Data Provider" 
           type="Eli.Sample.MyDataProvider, Sample.MyDataProvider, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5b9d34470b87a97f" 
      />
    </DbProviderFactories>
</system.data>

我该怎么做呢？只需一个指针就可以了.谢谢.

如果你使用Wix,你可以使用XmlConfig元素.

<util:XmlConfig 
        Id="Machine_Config_Xml_Root"
        File="[WindowsFolder]Microsoft.NET\Framework\v2.0.50727\CONFIG\Machine.Config"
        Action="create" 
        On="install"
        ElementPath="//configuration/system.data/DbProviderFactories" 
        Name="add"
        Node="element" 
        Sequence="1"> 
 </util:XmlConfig> 
 <util:XmlConfig 
        Id="Machine_Config_Xml_2"
        File="[WindowsFolder]Microsoft.NET\Framework\v2.0.50727\CONFIG\Machine.Config"
        ElementPath="Machine_Config_Xml_Root"
        Name="name"
        Value="My Data Provider" 
        Sequence="2"> 
 </util:XmlConfig>

        Name="invariant"
        Value="Sample.MyDataProvider"
