问题
I've got a few properties stored in my AppConfig and now I want to access them dynamically (e.g. in a loop or function).
Accessing the values using MySettings.NAME_OF_THAT_THING is no problem, but what if the name is variable?
I tried:
String propertyValue = MySettings.GetType().GetProperty("NAME_OF_THAT_THING").ToString();
But the only thing I got back is the name of the property. How can I do this?
回答1:
String propertyValue = MySettings.GetType()
.GetProperty("NAME_OF_THAT_THING")
.GetValue(MySettings, null); //replace MySettings with null in GetValue(...) if MySettings is a static class
回答2:
All you need to do is:
String propertyValue = Settings.Default["NAME_OF_THAT_THING"].ToString();
While using reflection will obviously work, it's overkill.
回答3:
Have you tried using the ConfigurationManager.AppSettings property? You should be able to get your setting via the following code:
String propertyValue = ConfigurationManager.AppSettings["NAME_OF_THAT_THING"];
The MSDN article for ConfigurationManager.AppSettings also includes an example for looping through all of the entries in AppSettings by index, rather than name.

answer to the orginal poster question would be like: MySettings[NAME_OF_THAT_THINGmysettings] does the job like previous post
however for those people looking for answer to using the builtin settings in their windows app: myAppDefaultNameSpace.Properties.Settings.Default[NAME_OF_THAT_THINGmysettings] is the way to go
