Properties

BaseAddress

Gets the first byte address of the data source that is accessible.

public ulong BaseAddress { get; }

Property Value

ulong

this[ulong]

Reads a single byte at the provided address.

public byte this[ulong address] { get; }

Parameters

address ulong

The address to read from.

Property Value

byte

Length

public ulong Length { get; }

Property Value

ulong

Methods

IsValidAddress(ulong)

Determines whether the provided address is a valid address in the data source.

public bool IsValidAddress(ulong address)

Parameters

address ulong

The address to verify.

Returns

bool

true if the address is valid, false otherwise.

ReadBytes(ulong, byte[], int, int)

Reads a block of data from the data source.

public int ReadBytes(ulong address, byte[] buffer, int index, int count)

Parameters

address ulong

The starting address to read from.

buffer byte[]

The buffer that receives the read bytes.

index int
