Description(“中国good”) field have both Chinese characters and English characters, however, Oracle system rule: one Chinese character is equal to three English characters.
I get Description.length=6, in fact, i want get it’s length equal 10 which meet oracle rule.

Hi @Lori ,

You can use this code to get the actual length including your Chinese characters in the string. We have to get the byte code length.


To work with Encoding, you need to include System.Text namespace in your Import tab.
This will give you the output you are looking for.
