How can i use this query directly in LINQ C#

Answer 1

As you mentioned on comment section you don't want to translate SQL to LINQ, you just want to directly run this script.

To do so first you need to create class that will match with your Script like:

 [DataContract()]
 public class PaymentInvoiceResult
 {
    [DataMember]
    public int Id { get; set; }

    [DataMember]
    public int No { get; set; }

    [DataMember]
    public int NetAmount { get; set; }

    [DataMember]
    public int PaidAmount { get; set; }

    [DataMember]
    public int AmountToBePayed { get; set; }
 }

Then you need to use SqlQuery as following:

List<PaymentInvoiceResult> paymentInvoiceResultList = db.Database.SqlQuery<PaymentInvoiceResult>("Your Script").ToList(); 

Answer 2

You can simply use:

var results = db.ExecuteQuery(typeof(DTO), "sql query ");

Your dto should have members:

Id,
    No,
    NetAmount,
    PaidAmount,
    NetAmount - PaidAmount AS AmountToBePayed
