C# – Why isn’t this short circuit in lambda working


Why linq is trying to check second expression anyway?

.Where(t =>  String.IsNullOrEmpty(someNullString) || t.SomeProperty >= Convert.ToDecimal(someNullstring))

What is usual workaround?

It is about LINQ to SQL, of course. It cannot translate to SQL.

Best Solution

Is the .Where being used on a Table<>?

If so, then before any data can be grabbed, it must convert the LINQ to SQL and to do that it must convert the string into a decimal. It's not trying to actually perform the comparisons yet, it's trying to build the constructs necessary to retrieve data.
