Provides a controlled memory buffer that can be used for reading and writing. Attempts to access memory outside the controlled buffer (underruns and overruns) raise exceptions.
Assembly: mscorlib (in mscorlib.dll)
Thetype exposes the following members.
|AcquirePointer||Obtains a pointer from a object for a block of memory.|
|Close||Marks the handle for releasing and freeing resources. (Inherited from SafeHandle.)|
|DangerousAddRef||Manually increments the reference counter on SafeHandle instances. (Inherited from SafeHandle.)|
|DangerousGetHandle||Returns the value of the handle field. (Inherited from SafeHandle.)|
|DangerousRelease||Manually decrements the reference counter on a SafeHandle instance. (Inherited from SafeHandle.)|
|Dispose()||Releases all resources used by the SafeHandle class. (Inherited from SafeHandle.)|
|Dispose(Boolean)||Releases the unmanaged resources used by the SafeHandle class specifying whether to perform a normal dispose operation. (Inherited from SafeHandle.)|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Frees all resources associated with the handle. (Inherited from SafeHandle.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|Initialize(UInt64)||Defines the allocation size of the memory region in bytes. You must call this method before you use the instance.|
|Initialize(UInt32, UInt32)||Specifies the allocation size of the memory buffer by using the specified number of elements and element size. You must call this method before you use the instance.|
|Initialize<T>(UInt32)||Defines the allocation size of the memory region by specifying the number of value types. You must call this method before you use the instance.|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|Read<T>||Reads a value type from memory at the specified offset.|
|ReadArray<T>||Reads the specified number of value types from memory starting at the offset, and writes them into an array starting at the index.|
|ReleaseHandle||When overridden in a derived class, executes the code required to free the handle. (Inherited from SafeHandle.)|
|ReleasePointer||Releases a pointer that was obtained by the AcquirePointer method.|
|SetHandle||Sets the handle to the specified pre-existing handle. (Inherited from SafeHandle.)|
|SetHandleAsInvalid||Marks a handle as no longer used. (Inherited from SafeHandle.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|Write<T>||Writes a value type to memory at the given location.|
|WriteArray<T>||Writes the specified number of value types to a memory location by reading bytes starting from the specified location in the input array.|
You must call the SafeBuffer.Initialize method before you use any instance of . To avoid races when you store an instance of a object in a static variable, you should use one of the following approaches:
Create a lock when publishing the .
Create a local variable, initialize the , and then assign the to the static variable, for example, by using the Interlocked.CompareExchange method.
Assignments in a static class constructor are implicitly locked.
requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.
