有没有办法获得一个System.Configuration.Configuration实例基于任意xml? [英] Is there a way to get a System.Configuration.Configuration instance based on arbitrary xml?
问题描述
我尝试单元测试我编写的自定义ConfigurationSection,我想将一些任意配置XML加载到 System.Configuration.Configuration 每个测试(而不是把测试配置xml放在Tests.dll.config文件中,也就是说,I 'd喜欢这样做:
I'm trying to unit test a custom ConfigurationSection I've written, and I'd like to load some arbitrary configuration XML into a System.Configuration.Configuration for each test (rather than put the test configuration xml in the Tests.dll.config file. That is, I'd like to do something like this:
Configuration testConfig = new Configuration("<?xml version=\"1.0\"?><configuration>...</configuration>");
MyCustomConfigSection section = testConfig.GetSection("mycustomconfigsection");
Assert.That(section != null);
但是,它看起来像 ConfigurationManager 只会提供与EXE文件或机器配置相关联的配置实例。有没有办法将任何XML加载到配置实例?
However, it looks like ConfigurationManager will only give you Configuration instances that are associated with an EXE file or a machine config. Is there a way to load arbitrary XML into a Configuration instance?
推荐答案
您需要定义一个继承自原始配置部分的新类,如下所示:
You need to define a new class inheriting from your original configuration section as follows:
public class MyXmlCustomConfigSection : MyCustomConfigSection
{
public MyXmlCustomConfigSection (string configXml)
{
XmlTextReader reader = new XmlTextReader(new StringReader(configXml));
DeserializeSection(reader);
}
}
实例化您的ConfigurationSection对象,如下所示:
You can then instantiate your ConfigurationSection object as follows:
string configXml = "<?xml version=\"1.0\"?><configuration>...</configuration>";
MyCustomConfigSection config = new MyXmlCustomConfigSection(configXml);
