name suggestion for boolean expression in c#

In C#, when you're naming variables representing Boolean values, the advice is to use names that directly reflect the state that they represent. This improves code readability, making it more understandable to whoever reads your code next.
Here are some rules to follow when you're naming Boolean variables:

Use a prefix that clearly denotes it as a Boolean. Some developers prefer to use "can", "is", "has", or "should" as a prefix.
Avoid negative words in the name. If you use a negative word in the name (like "isNotAvailable"), it might lead to confusing double negatives when the variable's value is false.
Make it clear what true and false mean for the variable.
Here are some examples:

isAvailable instead of Availability
hasCompleted instead of CompletionStatus
canEdit instead of Editability
shouldUpdate instead of UpdateStatus

These are better because it is clear that a true value for isAvailable means the item is available, whereas a true value for Availability is ambiguous. The same clarity applies to the other examples. By naming your variables well, you make your code easier to read and maintain.
