Using Remove Method
A remove method is a basic method which removes the key from the cache and returns the removed object to the cache.
string key = "Product:1001";
Product product = null;
try
{
// null is returned if key does not exist in cache
object result = cache.Remove(key);
if (result != null)
{
if (result is Product)
{
product = (Product)result;
}
}
}
catch (OperationFailedException ex)
{
// handle exception
}
Using Delete Method
A delete method is a basic method which deletes the key from the cache.
string key = "Product:1001";
try
{
cache.Delete(key);
}
catch (OperationFailedException ex)
{
// handle exception
}
