MemoryStream.GetBuffer Method
Returns the array of unsigned bytes from which this stream was created.
Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)
Return Value
Type: System.Byte[]The byte array from which this stream was created, or the underlying array if a byte array was not provided to the MemoryStream constructor during construction of the current instance.
| Exception | Condition |
|---|---|
| UnauthorizedAccessException |
The MemoryStream instance was not created with a publicly visible buffer. |
Note that the buffer contains allocated bytes which might be unused. For example, if the string "test" is written into the MemoryStream object, the length of the buffer returned from GetBuffer is 256, not 4, with 252 bytes unused. To obtain only the data in the buffer, use the ToArray method; however, ToArray creates a copy of the data in memory.
The buffer can also be null.
To create a MemoryStream instance with a publicly visible buffer, use MemoryStream, MemoryStream(Byte[], Int32, Int32, Boolean, Boolean), or MemoryStream(Int32). If the current stream is resizable, two calls to this method do not return the same array if the underlying byte array is resized between calls. For additional information, see Capacity.

This method works when the memory stream is closed. |
