Syntax

public static class BinaryReaderExtensions

Methods

GetBinaryReadMethod(Type)

Gets a read method defined in the BinaryReader class that can be used to read an object of the specified type.

Declaration

public static MethodInfo? GetBinaryReadMethod(Type t)

Parameters

Type	Name	Description
Type	t	Type for which to get a read method defined in the BinaryReader class.

Returns

Type	Description
MethodInfo	A read method defined in the BinaryReader class that can be used to read an object of the specified type, or null if no read method exists for the specified type.

MarshalReadArray<T>(BinaryReader, in int)

Reads an array of type T by marshaling.

Declaration

public static T[] MarshalReadArray<T>(this BinaryReader br, in int count) where T : struct

Parameters

Type	Name	Description
BinaryReader	br	BinaryReader to be used for reading.
int	count	Number of elements to be read.

Returns

Type	Description
T[]	An array of T containing count elements.

Type Parameters

Name	Description
T	Type of elements to be read. Must be a struct readable by marshaling.

MarshalReadArray<T>(BinaryReader, in long, in int)

Moves to a specific location in the Stream being read by the BinaryReader and reads an array of type T by marshaling.

Declaration

public static T[] MarshalReadArray<T>(this BinaryReader br, in long offset, in int count) where T : struct

Parameters

Type	Name	Description
BinaryReader	br	BinaryReader to be used for reading.
long	offset	Offset from which to start reading the array.
int	count	Number of elements to be read.

Returns

Type	Description
T[]	An array of T containing count elements.

Type Parameters

Name	Description
T	Type of elements to be read. Must be a struct readable by marshaling.

MarshalReadStruct<T>(BinaryReader)

Reads a simple structure from the reader using marshaling.

Declaration

public static T MarshalReadStruct<T>(this BinaryReader reader) where T : struct

Parameters

Type	Name	Description
BinaryReader	reader	Instance of BinaryReader from which to perform the read.

Returns

Type	Description
T	The value read from reader.

Type Parameters

Name	Description
T	Type of value to read.

Remarks

This function differs from Read<T>(BinaryReader) in that the read will be performed exclusively using marshaling techniques, without including the default functions and/or those implemented in the BinaryReader class or a known extension method of it.

This method also requires that strings and arrays be annotated with the MarshalAsAttribute, setting a constant maximum expected size for the string or array. To read structures with strings or arrays of arbitrary size, consider using ReadStruct<T>(BinaryReader).

ReadStruct<T>(BinaryReader)

Read(BinaryReader, Type)

Reads a value of the specified type from the reader.

Declaration

public static object Read(this BinaryReader reader, Type type)

Parameters

Type	Name	Description
BinaryReader	reader	Instance of BinaryReader from which to read.
Type	type	Type of value to read.

Returns

Type	Description
object	The value read from reader.

Remarks

If you know the exact type of the value to read and a method exists in the BinaryReader class or an extension is defined for reading that value, prefer using that method or extension for better performance. Additionally, if the value to read is a simple user-defined structure, you can use the MarshalReadStruct<T>(BinaryReader) method to read a structure using marshaling, which may provide better performance than using this method.

Also, note that this method will read structures by reading the values of their fields, including both private and public fields (and therefore, properties).

Exceptions

Type	Condition
InvalidOperationException	Thrown if no read method exists for the specified type.

Declaration

public static DateTime ReadDateTime(this BinaryReader br)

Parameters

Type	Name	Description
BinaryReader	br	BinaryReader from which to read.

Returns

Type	Description

ReadEnum(BinaryReader, Type)

Reads an enumeration value.

T	Type of value to read.

Remarks

This method allows reading structures based on their fields, both private and public (and therefore, including properties with backing fields), as long as they are writable, i.e., not declared as readonly.

If the structure does not contain arbitrarily-sized strings or arrays, or those have been annotated with the MarshalAsAttribute attribute setting the SizeConst property, consider using the MarshalReadStruct<T>(BinaryReader) method, as it may provide better performance.
