DataService how do you pass LONG

Question

how do you pass long type parameter with data services? It passes INT with no problems, but what could be the solution for LONG? I tried the method that I use for strings for joke, doesn't seem to work.

public TransactionCartItem GetTransactionCartItemByTransactionNumber(long transactionNumber)
{
    transactionNumber = (int)transactionNumber; // it works if I convert to INT (just for debugging reason I tried)

    var query =
        this.ClientRepositories
            .Context
            .CreateQuery<TransactionCartItem>("GetTransactionCartItemByTransactionNumber")
            .AddQueryOption("transactionNumber", transactionNumber)
            .FirstOrDefault();

    return query;
}

Error for LONG usage:

“Bad Request - Error in query syntax.”

I think OData needs long (Int64) values in Url to be appended with L.

Try this and let us know.

public TransactionCartItem GetTransactionCartItemByTransactionNumber(long transactionNumber)
{   
    var query =
        this.ClientRepositories
            .Context
            .CreateQuery<TransactionCartItem>("GetTransactionCartItemByTransactionNumber")
            .AddQueryOption("transactionNumber", transactionNumber + "L")
            .FirstOrDefault();

    return query;
}

got the documentation.. the Edm.Int64 seems to need a trailing L at the end. http://www.odata.org/documentation/odata-version-2-0/overview/#AbstractTypeSystem
