TryReadValue Method
TryReadValue(out ReadOnlyMemory<byte>, int)
Try to read the TLV at the current position. If this succeeds, return
true and set the value argument to a new ReadOnlyMemory
object containing the value as a byte array, and move the position to
the byte beyond the current TLV.
public bool TryReadValue(out ReadOnlyMemory<byte> value, int expectedTag)Parameters
| Type | Name | Description |
|---|---|---|
| ReadOnlyMemory<byte> | value | The output parameter where the value will be deposited. |
| int | expectedTag | The tag that should be at the current position. |
Returns
A boolean, true if the read succeeds, false otherwise.
Remarks
This is the same as ReadValue, 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
there is not enough data in the buffer for the length given, this
method will return false.
See the documentation for ReadValue for more information
on what this method does.
Note that the value returned is a reference to the input encoding. Do not clear or alter the encoding until after the full encoding has been read and each value operated on.
