IsolatedStorage.Quota Property

When overridden in a derived class, gets a value that represents the maximum amount of space available for isolated storage.

Namespace:  System.IO.IsolatedStorage
Assembly:  mscorlib (in mscorlib.dll)

public virtual long Quota { get; internal set; }

Property Value

Type: System.Int64
The limit of isolated storage space, in bytes.


An operation was performed that requires access to Quota, but that property is not defined for this store. Stores that are obtained by using enumerations do not have a well-defined Quota property, because partial evidence is used to open the store.

The IsolatedStorageFile.Quota property overrides this property.
