underline The TextNote retrieve the length of IndependentTag.text

[1368026189]

Hello Everybody:

 

I got a question about tag my Pipe and draw a detail line under it,but I can not retrieve the Text Length ,If I compute the text bytelength, the length differs when the font changes.I got an method to compute the length via create a TextNote and retrieve the textnote width, it works fine In Revit Above Revit 2016,but in Revit 2014 and 2015,the TextNote is old doc.create.NewTextNote,and I always get the same width , in another word,It does'nt act well as In Revit 2016. So How can I get the length In Revit 2014 and 2015?

Below is my code.

thanks!
