Hello. I'm trying to get value from my appconfig file but i can't. Here is what i've done so far:

-Added appconfig by right click to project-add-new item-Application Configuration File
-Created an appSettings node and added a key and value to it:

<configuration>
  <appSettings>
    <add key="openwin" value="false"/>
  </appSettings>
</configuration>

-Added System.Configuration as Referance
-Called value of my key in program:

 Dim appValue As String
appValue = System.Configuration.ConfigurationManager.AppSettings("openwin")
MsgBox(appValue)

This should give me the "false" value but it doesn't, it simply giving "Nothing" to me.

Solution 2

If you having multiple project in your solution, and say the startup project is webapplication and you having the below code

C#

<add key="openwin" value="false" />

in Data Access Layer (DAL)[class library project] means that doesn't make any sense you have to add that in startup project say here as webapplication's web.config file.

I found the problem, the problem was my config file wasn't in the same folder with my exe and it should be named as ApplicationName.ApplicationType.config like myprogram.exe.config

Thanks for the link Wes Aday!

Solution 4

Try with the following:

C#

System.Configuration.ConfigurationSettings.AppSettings["openwin"].ToString();
OR
(string)System.Configuration.ConfigurationSettings.AppSettings.Get("openwin");
