ReSharper: Can I make my own context action?
ReSharper has a "Check parameter for null" context action, that will automatically insert code to check an argument for null and throw ArgumentNullException if it is null.
If the parameter is a string, I would like another option: "Check string for Null or empty". This should generate code something similar to this:
if (String.IsNullOrEmpty(result))
throw new ArgumentException("Parameter cannot be null or empty", "result");
Is the开发者_开发技巧re any way to add this to ReSharper easily ?
I've created ReSharper live templates for check for null and check for empty string.
So pnn
+ Enter inserts a parameter not null check etc.
The code for pnn
looks like this
if($ARG$ == null)
throw new $ARGNULLEXC$("$ARG$");$END$
Where $ARG$
is "Suggest parameter of type System.Object" and $ARGNULLEXC$
is "insert reference to System.ArgumentNullException". The $END$
indicates where your cursor should be after inserting the live template.
For the string variant, you would assign $ARG$
something like "Suggest parameter of type System.String".
