Use this method to remove key-value pairs from isolated storage. If the key does not exist, the method returns false; no entry is deleted and no exception is thrown.
The following example tries to remove a key-value pair for the user's name from the settings dictionary. A message is displayed in a TextBox named tbResults that indicates whether the name was removed or not found. This example is part of a larger example for the IsolatedStorageSettings class.
If userSettings.Remove("name") = True Then
tbResults.Text = "Name removed. Refresh page to see changes."
Else
tbResults.Text = "Name could not be removed. Key does not exist."
End If
if (userSettings.Remove("name") == true)
{
tbResults.Text = "Name removed. Refresh page to see changes.";
}
else
{
tbResults.Text = "Name could not be removed. Key does not exist.";
}
