IsolatedStorage.MaximumSize Property

Note: This API is now obsolete. The non-obsolete alternative is Quota.

Gets a value representing the maximum amount of space available for isolated storage. When overridden in a derived class, this value can take different units of measure.

This API is not CLS-compliant. 

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

[CLSCompliantAttribute(false)]
[ObsoleteAttribute("IsolatedStorage.MaximumSize has been deprecated because it is not CLS Compliant.  To get the maximum size use IsolatedStorage.Quota")]
public virtual ulong MaximumSize { get; }

Property Value

Type: System.UInt64
The maximum amount of isolated storage space in bytes. Derived classes can return different units of value.

ExceptionCondition
InvalidOperationException

The quota has not been defined.

The default implementation of the MaximumSize property returns the value of IsolatedStoragePermission.UserQuota, which is expressed in bytes. Derived classes can express the value in other units of measure. A potential example of such an implementation is an isolated storage database.

You cannot set MaximumSize, but the quota is configured in the security policy, and can be set. Code receives a quota of space on the basis of its evidence, so the same code can receive a different quota if it is run with different evidence (for example, the same application run locally and from a share on an intranet can receive different quotas). IsolatedStorageFile.MaximumSize implements this property.
