Remarks

For more info, see Quickstart: Reading and writing a file, which shows how to read and write bytes to a file by using a Buffer.

Constructors

Buffer(UInt32) Buffer(UInt32) Buffer(UInt32) Buffer(UInt32)

Initializes a new instance of the Buffer class with the specified capacity.

public : Buffer(unsigned int capacity)public Buffer(UInt32 capacity)Public Sub New(capacity As UInt32)// You can use this method in JavaScript.
Parameters
capacity
unsigned int UInt32 UInt32 UInt32

The maximum number of bytes that the buffer can hold.

Properties

Capacity Capacity Capacity Capacity

Gets the maximum number of bytes that the buffer can hold.

public : unsigned short Capacity { get; }public uint Capacity { get; }Public ReadOnly Property Capacity As uint// You can use this property in JavaScript.
Value
unsigned short uint uint uint

The maximum number of bytes that the buffer can hold.

Length Length Length Length

Gets the number of bytes currently in use in the buffer.

public : unsigned short Length { get; set; }public uint Length { get; set; }Public ReadWrite Property Length As uint// You can use this property in JavaScript.
Value
unsigned short uint uint uint

The number of bytes currently in use in the buffer, which is less than or equal to the capacity of the buffer.

Methods
