.net - Operator '=' Is Not Defined For Types 'Integer' And 'IQueryable(Of Integer)'

Aug 3, 2010

This is giving me a headache. I have this link query here that grabs an ID

Dim mclassID = From x In db.SchoolClasses Where x.VisitDateID = _visitdateID Select x.ClassID And then later on I have this linq query

ViewData("Staff") = From t In db.Staffs Where t.ClassID = mclassID Select t

I've tried quite a few things but to no avail. I've attempted casting, converting, Is operand, etc.

Value Of Type 'System.Linq.IQueryable(Of Integer)' Cannot Be Converted To Integer?

Aug 11, 2011

I am new to EF Linq and I have been struggling with this query for a few days. From reading this forum, I have managed to get this far:

Dim noPic = (From f In myEntities.FriendLists
Where (f.UserID = Profile.ID)
Select f.FriendID).Except(From g In myEntities.GuestLists
Where g.EventID = _id
Select g.FriendID)

[Code]...

I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?

Ternary Operator VB Vs C# Resolves To Integer

Nov 10, 2010

Suppose we have a nullable value in vb.net: Dim i as Integer? We want to assign a value to it, basing on a condition, and using a ternary operator, because it's so neat and stuff: i = If(condition(), Nothing, 42) That is, if a condition is true, employ the null-ability, otherwise the value. At which point the shooting occurs. For no apparent reason VB compiler decides that the common base type for Nothing and Integer is Integer, at which point it silently translates the statement to: [Code]

Implement A Custom Operator For Integer Type?

I have been developing in VB.net for a cople of years now. I really miss the increment and decrement operators for integers that I grew attached to while using Java and C#.

Assign A Value To Nullable Integer Via A Ternary Operator / It Can't Become Null

Apr 19, 2012

If you assign a value to a nullable integer via a ternary operator, it can't become null..While this question may seem like a duplicate of many, it is actually being asked for a specific reason.Take this code, for example: Dim n As Integer? = If(True, Nothing, 1) In that code, the ternary expression should be returning Nothing, but it's setting n to 0. If this were C#, I could say default(int?) and it would work perfectly. Now it looks like I am going to have to ditch the ternary and use a regular If block, but I really want to use the ternary. If Nothing were truly VB.NET's equivalent to C#'s default, how can you explain this behavior?

Is there a way to use a generic that only accepts integer types?

I have a Clamp(value, min, max) function, and it would be nice if it could accept ints, uints, floats, shorts, ect without having to write an individual function for each type.

Override Basic Types Like Integer, String?

Nov 12, 2010

I am extending some of the basic data types in vb.net for a large application. This includes integer, string, short, etc. As it stands, my new data type objects have names like MYInteger and MYString. Since these are the only types I'm using for my application and they are mostly compatible with the default types, is there a way I can override the defaults with mine so when you Dim iThing as Integer you're actually using my slightly customized integer type?
