declaring a ? in advance to facilitate if

Question

User379720387 posted

Sorry, don't know what the name is.

This is my code.

var cshoeinfo = (from cs in client.ClientShoes
                         where cs.ProviderId == providerid select cs).FirstOrDefault());

Now I need to put it inside an if statement, how do I declare this?

I am used to doing this:

IENumerable<dynamic> cshoeinfo;

This causes "cannot covert type 'ClientShoe to Systems.Collection.Generic.dynamic."

ClientShoe cshoeinfo = null;
if(blah blah)
{ 
    cshoinfo = client.ClientShoes.FirstOrDefault(cs => cs.ProviderId == providerid);
}

Note: I have used method syntax for the query. You can use your version which is query syntax. The result is the same.

Another note, if you are unsure that type your LINQ query returns, hover over the var keyword in VS, It will tell you.

A final note, the error message also told you what the data type of cshoeinfo actually is.

It said class.

Thanks.

It should also have said ClientShoe.

Is your issue still unresolved?

Nope.

Must have hit 'mark as answer" twice.
