Visual Studio “if” snippet initially won't recognize variables

问题

I have a noob question. When I use the built in visual studio "if" snippet the expression in the parentheses won't initially recognize any of the variables in my class. I have tried google without much luck.

Here are my steps to reproduce:

1. I type "if" - the if statement snippet appears in my intellisense.
2. I hit enter or tab - the if statement is added. There is now a red box inside the parentheses that says "expr".
3. I now attempt to start typing my variable - nothing is found in the intellisense window.

I have found that if I delete the red box and then move the cursor outside of the parentheses then go back inside the parentheses, the intellisense will then pick up the variable.

My question is: Is there a better way to use the if snippet with variables? Is this my my computer?

Thanks Jonathon Chase for pointing me in the right direction. This seems to be an issue with the ReSharper if live template. I would assume some folks like it better that way. Looking through the JetBrains documentation I was able to make the template work the way I wanted.

Here's what I did to fix this issue:

1. Navigate to ReSharper > Tools > Templates Explorer
2. Select C# and then find the if template (not the #if template)
3. Change $expr$ to $expression$

Now save and it should work as expected.
