Unable to use String.Format() function in mailMessage.Body

[ahalfian (Ahmad Alfian)]

Hi all,

Sorry if this have been asked.
I tried to assign mailMessage.Body with String.Format(textfile, value0, value1) but it come up with below error :

Assign : Value cannot be null.
Parameter name: format

I am not sure. I have check textfile, value0 and value1 data, it is giving output.
When I assigned mailMessage.Body with single string (e.g textfile, value0 or value1), it worked. But not able to use using String.Format. Any idea guys?

Thanks!

You need give it as String.Format(“{0} {1} {2}”, textfile, value0, value1)

Because syntax is String.Format(“format string”, arg1 , arg2 , … )
