Posted April 20, Hi All, I've got a non-Citrix related issue affecting a specific user account in an AD domain that seems to have one stand-out attribute.

Paul, if you could give me a little more direction on how to test for the presence of data, I would be most appreciative.

Nota bene: The code in this answer has been written for a.
NET Core 2. NET Core you probably have to adjust the code slightly; these changes however should be small and easy as the Core and non-Core version of the libraries are very similar. Nothing fancy here, these are simply the properties defined in the TSProperty document. The userParameters and TSProperty documents define the structure of the payload. When saved the value of the property is converted to its binary representation, then the byte-array of the binary representation is converted to it hexadecimal string representation, then each character of the hexadecimal string representation is converted to its binary representation and then stored.
To create the encoded binary BLOB for the PropValue field, for each byte of the input create its ASCII-encoded hexadecimal representation and place this representation in 2 consecutive bytes of the output buffer, the most significant hexadecimal digit first followed by the least significant hexadecimal digit.
Hence, the output buffer corresponding to the input buffer byte containing character 'A' will be a sequence of 2 bytes whose hexadecimal representations are 34 and First of all, we need to prepare a container for the properties and the convert the data to a more manageable form:.
Why are we using MemoryStream and BinaryReader? Because it's really, really easier to use: instead of having to keep track of the offset where we should start to read from as we gradually proceed, we can simply call. ReadBytes int which is consuming and be on our way. We however should care about signature : when converted to a Unicode string it should always be equal to the string "P", if it's not there's something wrong with the data.
We don't really care for i , we only need to execute the content of the loop as many times as required. As previously stated we need to obtain nameLengthValue and valueLengthValue to know the length of the name of the property and the length of the value of the property.
Personally I'd throw an InvalidDataException if it's not equal to 0x We convert the value of propName back to a Unicode string to get the name of the property, and then the magic happens.
Because the output of the subtraction performed inside HexToInt produces an int, and the bitshift and bitmask operations output is an int, so converting the two nibbles to byte is a waste of resources, they would be converted back to int in the next instruction.
Thanks to CodesInChaos for his hex-to-byte conversion and black magic. Now we only have to convert the value to the correct type and assign it to the correct property of our class, we can do that with a simple if-else chain:. Nota bene: The CtxCfgPresent property is special, it should always be present and its value should always be equal to 0xB00B1E55 yes, I know, very funny.
If it's missing or its value is not equal to 0xB00B1E55 then the value of the attribute is corrupted and should not be used, personally I suggest throwing our friendly InvalidDataException in such cases. For those who managed to stay with me until the end, I've published a Minimal, Complete, and Verifiable example on GitHub I can't include the full code here due to character count limitations.
