Hi,

The process to add a worklog to an issue in Jira via REST is pretty straightforward in general, but I have to admit that I am not well versed in the use of C# programming language. 

• If you're using Jira Cloud, please checkout the Cloud: POST /rest/api/3/issue/{issueIdOrKey}/worklog endpoint for details. It might also help to review the Basic auth for REST APIs for details on how you can use an API Token to make such requests to a Cloud site. (You can also use OAuth for authorization, but it tends to be more complex to setup, but more secure).
• If you're using Jira Server/Data Center, then refer to the Server: POST /rest/api/2/issue/{issueIdOrKey}/worklog endpoint

Each of those documents have examples of using this endpoint.  For the Cloud version there are curl, php, node.js, java, and python specific syntax listed there that can help.  I am not sure of the exact C# syntax here, but it would have to follow the same headers/endpoint/payload being sent as the other examples.

For example, if you're using Jira Cloud, basic auth, and curl, you could send a request such as

curl --request POST \
  --url 'https://your-domain.atlassian.com/rest/api/3/issue/{issueIdOrKey}/worklog' \
  --header 'Authorization: Basic [base64encodedstring]' \
  --header 'Accept: application/json' \
  --header 'Content-Type: application/json' \
  --data '{
  "timeSpentSeconds": 12000,
  "started": "2020-09-23T07:30:36.640+0000"
}'

Of course you would need to substitute your URL, and IssueKey to make this work, but this is how it can be done. I also ran across another thread such as https://community.atlassian.com/t5/Answers-Developer-Questions/Using-c-to-access-jira-cloud-issues/qaq-p/535374 in which another user found the use of RestSharp to be helpful in being able to make such REST calls from C Sharp.

I hope this helps.
