IsolatedStorageFileStream.CanRead 属性

public:
 virtual property bool CanRead { bool get(); };

public override bool CanRead { get; }

member this.CanRead : bool

Public Overrides ReadOnly Property CanRead As Boolean

属性值

如果 IsolatedStorageFileStream 对象可读，则为 true；否则为 false。

示例

下面的代码示例演示如何使用 CanRead 属性，作为在调用 Read 或 BeginRead 方法之前查看流是否可以读取的检查。 有关此示例的完整上下文，请参阅 IsolatedStorageFileStream 概述。

IsolatedStorageFileStream source =
    new IsolatedStorageFileStream(this.userName, FileMode.OpenOrCreate,
    isoFile);
// This is the stream from which data will be read.
Console.WriteLine("Is the source file readable? " + (source.CanRead ? "true" : "false"));
Console.WriteLine("Creating new IsolatedStorageFileStream for Archive.");

// Open or create a writable file.
IsolatedStorageFileStream target =
    new IsolatedStorageFileStream("Archive\\ " + this.userName,
    FileMode.OpenOrCreate,
    FileAccess.Write,
    FileShare.Write,
    isoFile);

' Open or create a writable file.
Dim target As New IsolatedStorageFileStream("Archive\ " & Me.userName, _
     FileMode.OpenOrCreate, FileAccess.Write, FileShare.Write, isoFile)

注解

使用此属性可确定是否 IsolatedStorageFileStream 可以读取对象。
