Stream.CanSeek 属性
定义
当在派生类中重写时,获取指示当前流是否支持查找功能的值。When overridden in a derived class, gets a value indicating whether the current stream supports seeking.
public:
abstract property bool CanSeek { bool get(); };
public abstract bool CanSeek { get; }
member this.CanSeek : bool
Public MustOverride ReadOnly Property CanSeek As Boolean
属性值
如果流支持查找,为 true;否则为 false。true if the stream supports seeking; otherwise, false.
注解
如果从派生的类 Stream 不支持查找,则对 Length 、 SetLength 、和的调用 Position Seek 可能会引发 NotSupportedException 。If a class derived from Stream does not support seeking, calls to Length, SetLength, Position, and Seek may throw a NotSupportedException.
