Conditional breakpoint not working

问题

The above code has a conditional breakpoint set at its bottom line in yellow followed by the Breakpoint Settings dialog which should work with: item.Value == "aday"

However I get the below error, I have searched online for this and can't find any reason why this should fail. Im using VS 2015 Pro.

EDIT- Thank you for pointing out the obvious error on my part, I do normally code in C#. But now using a single '=' I get this??????? I assume that I it equates to an assignment, and adding parenthesis didn't help either?

回答1:

Just tested with a sample VB.NET project.
The problem is the ==. This is C# syntax but since you have a VB.NET application you should use a single equal

item.Value = "aday" 

(I have always something new to learn from SO)

回答2:

I am using the C# in Visual Studio 2017.

After search in an hour, conclusion was:

rewrite the conditional expression from:

item.Value == "aday"

to:

item != null && item.Value == "aday"

MAKE SURE item was not null. so that you can refer to field of value with item.Value

回答3:

If item.Value.Equals("aday") Then 'Temp If please remove
                    Debugger.Break()
                end if

Actually works in strict mode, Gasp!!!!

Thanks to all contributions, greatly appreciated :)
