IsolatedStorageFile.CurrentSize 属性

定义

命名空间:

System.IO.IsolatedStorage

程序集:

System.IO.IsolatedStorage.dll

Source:

IsolatedStorageFile.cs

注意

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。

获取独立存储的当前大小。

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.")]
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

属性值

UInt64

独立存储范围中当前正在使用的存储区的总字节数。

属性

CLSCompliantAttribute ObsoleteAttribute

例外

InvalidOperationException

该属性不可用。 当前存储区有漫游范围或者没有打开。

ObjectDisposedException

未定义当前对象的大小。

示例

下面的代码示例演示 了 CurrentSize 属性。 有关此示例的完整上下文，请参阅 IsolatedStorageFile 概述。

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()))

注解

表示独立存储范围内所有文件和目录的总使用情况。

无法准确确定参与漫游用户配置文件的商店的当前大小。 由于漫游配置文件通常缓存在多台客户端计算机上，然后与服务器同步，因此无法对此类存储强制实施配额，并且不会报告当前大小。

如何：预测具有独立存储的空间不足情况示例演示了 属性CurrentSize的使用。
