C# Expressions in template

[railkos]

Hi,

[[CallStartTimeLocal].AddHours([HoursFix]).ToString("yyyy-MM-dd HH:mm:ss.fff")]

This expression throws an error System.NullReferenceException at TcxLexicalParser.LexEvaluator.InstanceFunction

[[CallStartTimeLocal].AddHours(1).ToString("yyyy-MM-dd HH:mm:ss.fff")] works nomally

Any ideas how to fix, or another way to add custom time from "Parameters"?

Hello @railkos,

Using the parameter there will not work due to the way the expression is evaluated.

If you have only a few options, for example 1, 2 and 3, then maybe you can use conditionals. For example, to send a value using conditionals you would do something like this:
Instead of:

<Value Key="call_date_time">[[CallStartTimeLocal].AddHours([HoursFix]).ToString("yyyy-MM-dd HH:mm:ss.fff")]</Value>

You should use:

<Value Key="call_date_time" If="[HoursFix]==1">[[CallStartTimeLocal].AddHours(1).ToString("yyyy-MM-dd HH:mm:ss.fff")]</Value>
<Value Key="call_date_time" If="[HoursFix]==2">[[CallStartTimeLocal].AddHours(2).ToString("yyyy-MM-dd HH:mm:ss.fff")]</Value>
<Value Key="call_date_time" If="[HoursFix]==3">[[CallStartTimeLocal].AddHours(3).ToString("yyyy-MM-dd HH:mm:ss.fff")]</Value>

You can add 24 lines like that if you want, or just the values that you consider valid...
