How To: Change the Value of a Setting Between Application Sessions
.NET Framework 4.5
At times, you might want to change the value of a setting between application sessions after the application has been compiled and deployed. For example, you might want to change a connection string to point to the correct database location. Since design-time tools are not available after the application has been compiled and deployed, you must change the setting value manually in the file.
To Change the Value of a Setting Between Application Sessions
-
Using Microsoft Notepad or some other text or XML editor, open the .config file associated with your application.
-
Locate the entry for the setting you want to change. It should look similar to the example presented below.
<setting name="Setting1" serializeAs="String" > <value>My Setting Value</value> </setting>
-
Type a new value for your setting and save the file.
