Methods

FromReader(ref BinaryStreamReader)

Reads a DOS header structure at the current position of the provided input stream.

public static DosHeader FromReader(ref BinaryStreamReader reader)

Parameters

reader BinaryStreamReader

The input stream to read from.

Returns

DosHeader

The read DOS header.

Exceptions

BadImageFormatException

Occurs when the input stream does not point to a valid DOS header.

GetPhysicalSize()

Computes the number of bytes that the structure contains.

public override uint GetPhysicalSize()

Returns

uint
