How can a list of string variables be utilized within the body of an email and i want to add comma(,) separated.
Hi @Ravi_Rawal
Welcome to the community!
As I understand from the above that you have a list of string and you want to concat all the items present in the list in a string variable and use it in your email body.
For this you can follow few steps:
- Create string variable say Joined_string
- Use a assign activity to save the value in Joined_string by using the expression String.Join(", ",ListOfString)
- Use the Joined_string in your email body.
Let me know if this works for you!
