.NET Framework Class Library

IsolatedStorageFile..::.MaximumSize Property

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)

Syntax

Visual Basic (Declaration)

<CLSCompliantAttribute(False)> _
Public Overrides ReadOnly Property MaximumSize As ULong

Visual Basic (Usage)

Dim instance As IsolatedStorageFile
Dim value As ULong

value = instance.MaximumSize

[CLSCompliantAttribute(false)]
public override ulong MaximumSize { get; }

Visual C++

[CLSCompliantAttribute(false)]
public:
virtual property unsigned long long MaximumSize {
    unsigned long long get () override;
}

JScript

public override function get MaximumSize () : ulong

Property Value

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

Exceptions

Exception	Condition
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.

Remarks

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.

Examples

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

Visual Basic

Dim writer As New StreamWriter(isoStream)
' Update the data based on the new inputs.
writer.WriteLine(Me.NewsUrl)
writer.WriteLine(Me.SportsUrl)

'  Calculate the amount of space used to record this user's preferences.
Dim d As Double = Convert.ToDouble(isoFile.CurrentSize) / Convert.ToDouble(isoFile.MaximumSize)
Console.WriteLine(("CurrentSize = " & isoFile.CurrentSize.ToString()))
Console.WriteLine(("MaximumSize = " & isoFile.MaximumSize.ToString()))

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());

Visual C++

StreamWriter^ writer = gcnew 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 = {0}", isoFile->CurrentSize.ToString() );
Console::WriteLine( "MaximumSize = {0}", isoFile->MaximumSize.ToString() );
