What type is Model? What type does "Count()" return?

Solution 1

Try with this:

if (Model!=null) && (Model.Count<2)) <br />
{<br />
}

Explanation: only when the model is not null (fisrt condition) chek if the model.count is less than 2

Yes it is working but when it goes in else condition then geting error in
else{
foreach (var p in Model)

}

Object reference not set to an instance of an object.

Solution 2

I think that the problem is that Model is null, and you do not expect that.

how to use when foreach (var p in Model)
{
is null then it does not get error

Member 7870345 7-Jul-17 5:39am

If Model is null, its imposible to enumerate Model (basically what foreach does).
Conceptually it has no sense
How to iterate, enumerate somethis that not exists?

In my opinion there is a previous error that makes the Model null (perhaps a bad parameter in the call)
