c# - ConfigurationManager is not refreshing the AppSettings after a new execution -

in web application (c# + asp.net) can use new values on config file (install.properties) when try values using "configurationmanager".

string pathjava = configurationmanager.appsettings["filepathjava"];

i have got in install.properties

<add key="filepathjava" value="c:\program files\java\jre7\bin\java.exe"></add>

i rode can refresh values:

configurationmanager.refreshsection("appsettings");

i did this:

configurationmanager.openmachineconfiguration()

but value not change.

also tried add new key, configurationmanager returns me null value.

you have potential problem...

if change value in web.config, while site running, reset web site. modification whatsoever files causes iis reset occur.

a solution want, without resetting web site move application settings out of web.config altogether:

<?xml version="1.0"?> <configuration>    <appsettings configsource="appsettings.config"/> </configuration>

and place appsettings in appsettings.config file:

<?xml version="1.0"?> <appsettings>   <add key="filepathjava" value="c:\program files\java\jre7\bin\java.exe"/> </appsettings>

now, can still use configurationmanager.appsettings["filepathjava"], , configurationmanager.refreshsection("appsettings") should work well.
