TryReadUInt16 Method

TryReadUInt16(out UInt16, Int32, Boolean)

Try to read the TLV at the current position. If this succeeds, return true and set the value argument to the unsigned short that is the V part of the TLV, and move the position to the byte beyond the current TLV.

C#

public bool TryReadUInt16(out ushort value, int expectedTag, bool bigEndian = true)

Parameters

Type	Name	Description
System.UInt16	value	The output parameter where the value will be deposited.
System.Int32	expectedTag	The tag that should be at the current position.
System.Boolean	bigEndian	Specifies whether the result should be returned as big endian (true or no argument given) or little endian (false).

Returns

System.Boolean

A boolean, true if the read succeeds, false otherwise.

Remarks

This is the same as ReadUInt16(Int32, Boolean), except this method will not throw an exception if there is an error in reading, only return false. That is, if the expected tag is not found at the current position, or the length octets are not a valid encoding, or the value is not exactly two bytes, or there is not enough data in the buffer for the length given, this method will set value to 0 and will return false.

See ReadUInt16(Int32, Boolean) for more information on what this method does.

Note that if there is a valid TLV with the expected tag, but the length is not 2, this method will return false.
