IsolatedStorageFileStream.Position 属性

定义

命名空间:

System.IO.IsolatedStorage

程序集:

System.IO.IsolatedStorage.dll

Source:

IsolatedStorageFileStream.cs

获取或设置当前 IsolatedStorageFileStream 对象的当前位置。

public:
 virtual property long Position { long get(); void set(long value); };

public override long Position { get; set; }

member this.Position : int64 with get, set

Public Overrides Property Position As Long

属性值

Int64

此 IsolatedStorageFileStream 对象的当前位置。

例外

ArgumentOutOfRangeException

该位置不能设置为负数。

示例

下面的代码示例使用 Position 属性将数据写入文件。

Console::WriteLine( "Writing data to the new file." );
while ( source->Position < source->Length )
{
   inputChar = (Byte)source->ReadByte();
   target->WriteByte( (Byte)source->ReadByte() );
}

// Determine the size of the IsolatedStorageFileStream
// by checking its Length property.
Console::WriteLine( "Total Bytes Read: {0}", source->Length.ToString() );

Console.WriteLine("Writing data to the new file.");
while (source.Position < source.Length)
{
    inputChar = (byte)source.ReadByte();
    target.WriteByte(inputChar);
}

// Determine the size of the IsolatedStorageFileStream
// by checking its Length property.
Console.WriteLine("Total Bytes Read: " + source.Length);

Console.WriteLine("Writing data to the new file.")
While source.Position < source.Length
    inputChar = CByte(source.ReadByte())
    target.WriteByte(inputChar)
End While

' Determine the size of the IsolatedStorageFileStream
' by checking its Length property.
Console.WriteLine(("Total Bytes Read: " & source.Length))

注解

当 属性为 true时，CanSeek设置此属性有效。
