Sample: TxtRecord

[glararan]

I wonder how to read key/value from TxtRecord.

I have following code

IDnsQueryResponse response = await dnsClient.QueryAsync(domainInfo.Hostname, QueryType.TXT);

IEnumerable<DnsClient.Protocol.TxtRecord> records = response.Answers.TxtRecords();

However TxtRecord has only available properties: Text which is ICollection<string>. I suppose its value field splitted by ; or whitespace?

How I am suppose to retreive key?
e.g.:

Key: google.com
Value: docusign=05958488-4752-4ef2-95eb-aa7ba8a3bd0e

Thanks

There is a collection of strings because a TXT resource record can be used to store multiple values.
If quotes are used, the whole value within the quotes is treated as one value (and will produce only one element in the collection); e.g. "some text with spaces".
The same value without quotes would be 4 different values and would create a list of 4 strings.

In your example, all values are in quotes so the full text will be in the first element of the collection I guess.

Different systems then use different mechanisms to separate key/values. You'll have to parse the string yourself if you want to analyse any of the data.
