The following exception types are too general to provide sufficient information to the user:

The following exception types are reserved and should be thrown only by the common language runtime:

How to Fix Violations
To fix a violation of this rule, change the type of the thrown exception to a specific type that is not one of the reserved types.

How do I fix this even after using applicationexception object it is throwing hte same eroro
As it is being suggedted by your coding rules... you should be using one of the specific execption types and not the general type exception.
I guess in your case, since argument value range is wrong you can throw something like.

throw new ArgumentException(".....");
