有没有一种方法可以将web.config配置文件属性与外部配置文件合并？

Question

I have a situation where my web.config has some properties in the profile section

<profile>
...
  <properties  >
        <clear/>
        <add   type="System.String" name="propData"/>
        ...
  </properties>
</profile>

Now I want to add some other properties but from an external file (preserving current web.config for server settings, but deploying the external config file per build). Is there a way to merge the properties from the external file into my web.config so that I get

<profile>
...
  <properties  >
        <clear/>
        <add   type="System.String" name="propData"/>
        ...
        <add type="System.String" name="externalProp"/>
        ... 
  </properties>
</profile>

Can I do this using some web.config syntax like "configSource" or "file"?

Answer 1

You can update the web.config with required additional configurations from external config,

Example

var configuration = WebConfigurationManager.OpenWebConfiguration("~");
var section = (ConnectionStringsSection)configuration.GetSection("connectionStrings");
section.ConnectionStrings["MyConnectionString"].ConnectionString = "Data Source=...";
configuration.Save();

Programmatically manipulating web.config
