I have a medication table that I'm looking for certain drug names, but I need to search for multiple names. Here is where I currently am with it.
string[] names = new string[2];
names[0] = "apixaban";
names[1] = "desirudin";
var meds = (from m in Medications where names.Any(m.BrandName.Contains) || names.Any(m.GenericName.Contains) select m);
What I have isn't working, and I'm currently stuck. I know I'm close, but I can't quite figure out what's wrong.
EDIT
For clarification, if the name I'm searching for is desirudin, then the BrandName or Generic name will be longer, so I have to have the contains on the field in the database.
EDIT 2 Here is the error I recieve.
Unsupported overload used for query operator 'Any'.
Here is what I finally ended up with
var meds = (from m in db.AdmissionMedications where
(names.Any(n => m.BrandName.Contains(n)) || names.Any(n => m.GenericName.Contains(n))
) select m);
Well, you can just put multiple "where" clauses in directly, but I don't think you want to. Multiple "where" clauses ends up with a more restrictive filter - I think you want a less restrictive one.
Select(x => new { x, count = x. tags. Count(tag => list. Contains(tag)) }) .
Yes it supports General Arrays, Generic Lists, XML, Databases and even flat files. The beauty of LINQ is uniformity.
Maybe somthing like
C# Linq:
var meds = (from m in Medications
where names.Any(name => name.Equals(m.BrandName) || m.GenericName.Contains(name))
select m);
Extension methods:
List<Medication> meds = Medications
.Where( med =>
names.Any( name =>
name.Equals( med.BrandName ) || med.GenericName.Contains( name )
)
)
.ToList();
I think you want to try:
var query = Medications.Where(m => names.Contains(m.BrandName) || names.Contains(m.GenericName));
