注解

此类型还实现 COM 接口 IMemoryBufferByteAccess，该接口提供对缓冲区存储的直接访问。 有关如何访问缓冲区的 C# 示例，请参阅 自定义效果示例 。

注意

C++/WinRT 提供 上的 MemoryBuffer 扩展方法来直接访问数据。 各种语言和运行时提供访问进程内存的独特方式。 访问缓冲区时要小心，因为内存的生命周期与接口的 IMemoryBufferByteAccess 生命周期相关。

构造函数

MemoryBuffer(UInt32)

使用指定的容量初始化新的 MemoryBuffer 实例。

方法

Close()

断开此 MemoryBuffer 对象与实际内存缓冲区的连接。
CreateReference()

返回实现 IMemoryBufferReference 接口的新托管对象。
Dispose()

执行与释放或重置非托管资源关联的应用程序定义的任务。
