IsolatedStorageFile.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 within the limits established by the quota.

This API is not CLS-compliant. 

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

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

Property Value

Type: System.UInt64
The limit of isolated storage space in bytes.

ExceptionCondition
InvalidOperationException

The property is unavailable. MaximumSize cannot be determined without evidence from the assembly's creation. The evidence could not be determined when the object was created.

IsolatedStorageException

An isolated storage error occurred.

The number of bytes available is constrained by the isolated storage quota set by the administrator. Quota is configured in security policy on the basis of evidence, so the same code can receive a different quota if it is run with different evidence. For example, an application that is run locally and also from a share on an intranet would likely receive different quotas.

The How to: Anticipate Out-of-Space Conditions with Isolated Storage example demonstrates the use of the MaximumSize property.

The following code example demonstrates the MaximumSize property. For the complete context of this example, see the IsolatedStorageFile overview.


StreamWriter writer = new StreamWriter(isoStream);
// Update the data based on the new inputs.
writer.WriteLine(this.NewsUrl);
writer.WriteLine(this.SportsUrl);

// Calculate the amount of space used to record this user's preferences.
double d = isoFile.CurrentSize / isoFile.MaximumSize;
Console.WriteLine("CurrentSize = " + isoFile.CurrentSize.ToString());
Console.WriteLine("MaximumSize = " + isoFile.MaximumSize.ToString());
