IsolatedStorageFile.CurrentSize 屬性

定義

命名空間:

System.IO.IsolatedStorage

組件:

System.IO.IsolatedStorage.dll

來源:

IsolatedStorageFile.cs

警告

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

重要

此 API 不符合 CLS 規範。

取得隔離儲存區目前的大小。

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.")]

member this.CurrentSize : uint64

Public Overrides ReadOnly Property CurrentSize As ULong

屬性值

UInt64

隔離儲存區範圍內目前使用的儲存區位元組總數。

屬性

CLSCompliantAttribute ObsoleteAttribute

例外狀況

InvalidOperationException

找不到屬性。 目前的存放區有漫遊範圍或者沒有開啟。

ObjectDisposedException

尚未定義目前的物件大小。

範例

下列程式代碼範例示範 CurrentSize 屬性。 如需此範例的完整內容，請參閱概 IsolatedStorageFile 觀。

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()))

備註

表示隔離儲存範圍內所有檔案和目錄的總使用量。

目前的大小無法正確判斷參與漫遊使用者配置檔的存放區。 由於漫遊配置檔通常會在多部用戶端計算機上快取，且稍後與伺服器同步處理，因此無法針對這類存放區強制執行配額，而且不會報告目前的大小。

如何：使用隔離儲存區預測空間不足的情況範例示範 如何使用 CurrentSize 屬性。
