SOLID and DRY guidance declare that we should keep our C# code simple, narrow, and non-redundant. For instance, simple code like this:
var areSame =
string.Compare(mainStr, otherStr, CurrentCulture.CurrentCultureIgnoreCase) == 0;... is both ungainly and unnecessary. DRY does not refer to copying code like this, though it is certainly illegal:
var areSameCheckedAgainRedundantly =
string.Compare(mainStr, otherStr, CurrentCulture.CurrentCultureIgnoreCase) == 0;DRY means: no redundancy whatsoever, regardless of where it lurks. In this example, a parameter is redundant, and the check for 0 is both static (not a variable but also not even a constant!) and redundant. The fix is easy -- just use our SharedUtils extensions to code this quickly and safely:
using Com.MarcusTS.SharedUtils;
if (mainStr.isSameAs(otherStr))
{
}If you are looking for "not same as", then use this:
using Com.MarcusTS.SharedUtils;
if (mainStr.isDifferentThan(otherStr))
{
}SharedUtils provides similar comparison extensions for many C# types, including DateTime, numbers, and even IEnumerables!
SharedUtils also offers:
- A BetterObservableCollection that manages events more safely than in the C# version.
- A FlexibleStack that allows manipulation of a common stack.
- Reflection helpers
- Thread helpers,including a thread-safe Boolean
- Task helpers
- Numeric rounding
