"To handle both null and empty string scenarios, use IsEmpty / HasValue instead"

Rule description

You can avoid unnecessary clutter in your code by using IsEmpty or HasValue instead of string.IsNullOrEmpty() or string.IsNullOrWhiteSpace().

Example 1

public static void MyMethod(string myParam)
{
    if (string.IsNullOrEmpty(myParam) || string.IsNullOrWhiteSpace(myParam))
    {
        ...     
    }
}

should be 🡻

public static void MyMethod(string myParam)
{
   if (myParam.TrimOrEmpty().IsEmpty())
   {
       ...            
   }
}

Example 2

If your logic applies to null, but not empty string, then change the condition to ReferenceEquals.

if (token != null)
{
    ...
}

should be 🡻

if (! (token is null))
{
    ...
}
