BlockCopy()

static void System.Buffer.BlockCopy	(	Array	src,
		int	srcOffset,
		Array	dst,
		int	dstOffset,
		int	count
	)

Copies a specified number of bytes from a source array starting at a particular offset to a destination array starting at a particular offset.

Parameters

src	The source buffer.
srcOffset	The zero-based byte offset into src .
dst	The destination buffer.
dstOffset	The zero-based byte offset into dst .
count	The number of bytes to copy.

Exceptions

T:System.ArgumentNullException	src or dst is null.
T:System.ArgumentException	src or dst is not an array of primitives.-or- The number of bytes in src is less than srcOffset plus count .-or- The number of bytes in dst is less than dstOffset plus count .
T:System.ArgumentOutOfRangeException	srcOffset , dstOffset , or count is less than 0.

ByteLength()

static int System.Buffer.ByteLength ( Array  array )

static

Returns the number of bytes in the specified array.

Parameters

array

An array.

Returns

The number of bytes in the array.

Exceptions

T:System.ArgumentNullException	array is null.
T:System.ArgumentException	array is not a primitive.
T:System.OverflowException	array is larger than 2 gigabytes (GB).

Definition at line 183 of file Buffer.cs.

GetByte()

static byte System.Buffer.GetByte ( Array  array, int  index  )

static

Retrieves the byte at a specified location in a specified array.

Parameters

array	An array.
index	A location in the array.

Returns

Returns the index byte in the array.

Exceptions

T:System.ArgumentException	array is not a primitive.
T:System.ArgumentNullException	array is null.
T:System.ArgumentOutOfRangeException	index is negative or greater than the length of array .
T:System.OverflowException	array is larger than 2 gigabytes (GB).

MemoryCopy() [1/2]

static unsafe void System.Buffer.MemoryCopy ( void *  source, void *  destination, long  destinationSizeInBytes, long  sourceBytesToCopy  )

static

Copies a number of bytes specified as a long integer value from one address in memory to another. This API is not CLS-compliant.

Parameters

source	The address of the bytes to copy.
destination	The target address.
destinationSizeInBytes	The number of bytes available in the destination memory block.
sourceBytesToCopy	The number of bytes to copy.

Exceptions

T:System.ArgumentOutOfRangeException

sourceBytesToCopy is greater than destinationSizeInBytes .

Definition at line 416 of file Buffer.cs.

MemoryCopy() [2/2]

static unsafe void System.Buffer.MemoryCopy ( void *  source, void *  destination, ulong  destinationSizeInBytes, ulong  sourceBytesToCopy  )

static

Copies a number of bytes specified as an unsigned long integer value from one address in memory to another. This API is not CLS-compliant.

Parameters

source	The address of the bytes to copy.
destination	The target address.
destinationSizeInBytes	The number of bytes available in the destination memory block.
sourceBytesToCopy	The number of bytes to copy.

Exceptions

T:System.ArgumentOutOfRangeException

sourceBytesToCopy is greater than destinationSizeInBytes .

Definition at line 435 of file Buffer.cs.

SetByte()

static void System.Buffer.SetByte ( Array  array, int  index, byte  value  )

static

Assigns a specified value to a byte at a particular location in a specified array.

Parameters

array	An array.
index	A location in the array.
value	A value to assign.

Exceptions

T:System.ArgumentException	array is not a primitive.
T:System.ArgumentNullException	array is null.
T:System.ArgumentOutOfRangeException	index is negative or greater than the length of array .
T:System.OverflowException	array is larger than 2 gigabytes (GB).
