在App.config中修改自定义部分

Question

I have the following custom section in my config file:

<TestSettings>
    <EmailAddress></EmailAddress>
</TestSettings>

I tried to modify this section on runtime with the following method:

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var testSettings = ConfigurationManager.GetSection("TestSettings") as NameValueCollection;

if (testSettings != null)
{
    testSettings["EmailAddress"] = emailAddress;
    config.Save();
    ConfigurationManager.RefreshSection("TestSettings");
}

But the GetSection method returns null. What is the simplest way to solve this? Thank you.

Answer 1

So you running this from a test assembly . Re-read the method name:

ConfigurationManager.OpenExeConfiguration

Do you see it?

ConfigurationManager.Open Exe Configuration
