.NET Framework Class Library

IsolatedStorageFile..::.CurrentSize Property

Gets the current size of the isolated storage.

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 CurrentSize As ULong

Visual Basic (Usage)

Dim instance As IsolatedStorageFile
Dim value As ULong

value = instance.CurrentSize

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

Visual C++

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

JScript

public override function get CurrentSize () : ulong

Property Value

Type: System..::.UInt64
The total number of bytes of storage currently in use within the isolated storage scope.

Exceptions

Exception	Condition
InvalidOperationException	The property is unavailable. The current store has a roaming scope or is not open.
ObjectDisposedException	The current object size is undefined.

Remarks

Represents the total usage of all files and directories within the isolated storage scope.

The current size cannot be accurately determined for stores that are participating in a roaming user profile. Because roaming profiles are often cached on multiple client machines and later synchronized with a server, quotas cannot be enforced for such stores and the current size is not reported.

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

Examples

The following code example demonstrates the CurrentSize 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() );
