How to change the default storage quota of isolatedstorage

The last time we talked about how to change the default storage quota of isolatedstorage, I will introduce how to view the current usage of isolatedstorage.

First, open the Silverlight configuration page ):

Select ApplicationProgramStorage (Application storage) tab:

The current storage status is clear at a glance ~ Of course, I can also get these attributes in the program.

Using (Isolatedstoragefile ISF = Isolatedstoragefile. getuserstoreforapplication ())
{
ISF. availablefreespace. tostring () +   " Bytes " ; // Here is the remaining space
ISF. Quota. tostring () +   " Bytes " ; // Here is the current quota
(ISF. Quota - ISF. availablefreespace). tostring () +   " Bytes " ; // Here is the space used by the user
}

Okay. Now let's see how to change the default quota ~

 

Using (Isolatedstoragefile ISF = Isolatedstoragefile. getuserstoreforapplication ())
{
Try
{
If ( True   = ISF. increasequotato ( 1048576   *   2 )) // Increase the quota to 2 MB (note: the unit here is bytes)
{
Results. Text= "Quota changed successfully.";
}
Else
{
Results. Text= "Quota change failed.";
}
}
Catch (Exception E)
{
System. Windows. browser. htmlpage. Window. Alert (E. Message );
}
}

Easy ~ Some may ask where we stored the data last time.
