HP ALM OTA - How to add comments to a Test through C#?

Hi everyone,

Currently I'm designing something for HP ALM, my question is, using the ALM OTA API, how can I add comments to a test? It seems like it should be quite easy, but I'm stumped.

So far, I have something like this:

public Test getTestByID(string id, TDConnection conn)
{
TDFilter filter = conn.TestFactory.Filter; 

filter["TS_TEST_ID"] = id;
List<Test> result = filter.NewList().Cast<Test>().ToList();

result[0]["TS_DEV_COMMENTS"] = "Sample Comment";
result[0].Post();

return result[0];
}

The return is for other purposes, but regardless, this compiles but doesn't add any comments.

Also, since the comments are in HTML format, is there some sort of special process I need to do? Or will a regular string suffice?

Any help is appreciated, if more info is needed, I'll update.
