IsolatedStorageFile.CurrentSize Property

Definition

Namespace:

System.IO.IsolatedStorage

Assembly:

System.IO.IsolatedStorage.dll

Source:

IsolatedStorageFile.cs

Caution

IsolatedStorageFile.CurrentSize has been deprecated because it is not CLS Compliant. To get the current size use IsolatedStorageFile.UsedSize instead.

Important

This API is not CLS-compliant.

Gets the current size of the isolated storage.

public:
 virtual property System::UInt64 CurrentSize { System::UInt64 get(); };

[System.CLSCompliant(false)]
[System.Obsolete("IsolatedStorageFile.CurrentSize has been deprecated because it is not CLS Compliant. To get the current size use IsolatedStorageFile.UsedSize instead.")]
public override ulong CurrentSize { get; }

[<System.CLSCompliant(false)>]
[<System.Obsolete("IsolatedStorageFile.CurrentSize has been deprecated because it is not CLS Compliant. To get the current size use IsolatedStorageFile.UsedSize instead.")>]
member this.CurrentSize : uint64

Public Overrides ReadOnly Property CurrentSize As ULong

Property Value

UInt64

The total number of bytes of storage currently in use within the isolated storage scope.

Attributes

CLSCompliantAttribute ObsoleteAttribute

Exceptions

InvalidOperationException

The property is unavailable. The current store has a roaming scope or is not open.

ObjectDisposedException

The current object size is undefined.

Examples

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

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() );

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());

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()))

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.
