The behavior of a group of business processes is called a transaction. The business of this group can be processed successfully, and we can commit this transaction to save the results of your actions. The commit of a thing is to execute your method to commit the database, before the Sava is placed in the cache and not executed to the database.
- 1. Using TransactionScope
This is the most likely way to commit an ADO transaction. You need to reference the System.Transactions namespace.
var invoicedetailoriginal = invoicedetailservice.query (m = = M.detailid = = 86). FirstOrDefault (); using (TransactionScope transaction = new TransactionScope ()) {try { list<bl_invoice> invoicelst = new list<bl_invoice> (); list<bl_invoicedetail> detaillst = new list<bl_invoicedetail> (); var lst = invoiceservice.query (M = m.id > 49). ToList (); for (int n = 0; n < 3; n++) {Bl_invoice i = new Bl_invoice () {iswd = Lst[n]. ISWD, isazure = Lst[n]. Isazure, InvoiceNumber = Lst[n]. InvoiceNumber, invoicedate = DateTime.Now, Bittype = Lst[n]. Bittype, Bpexternalid = Lst[n]. Bpexternalid, CAExternalid = Lst[n]. Caexternalid, Amount = Lst[n]. Amount, ismethodsynced = False, METHOD_INCC = (n = = 1)? "XXXX": "P", createddate = DateTime.Now}; Bl_invoicedetail d = new Bl_invoicedetail () {Bl_invo Ice = i, BITREF32 = invoicedetailoriginal.bitref32, Mssku = (n = = 1) ? "Save 20 Chinese characters, save 20 characters, save 20 Chinese characters, save 20 Chinese characters, and save 20 Chinese characters." ": invoicedetailoriginal.mssku, Amount = Invoicedetailoriginal.amount, Tax = invoicedetailoriginal.tax, Deferralamount = Invoicedetailoriginal.deferralamount, Bitdate_from = invoicedetailoriginal.bitdate_from, bitdate_to = Invoice Detailoriginal.bitdate_to, CreatedDate = DateTime.Now}; Invoiceservice.add (i); Invoicedetailservice.add (d); To this step error, and then see Add invoice also not added on. This is the function of the transaction. Of course the Savachangge () of the entity can also be seen as a transaction. Transaction.complete (); }} catch (Exception ex) {throw ex; } finally {transaction. Dispose (); }
- 2. Savechangges () and Unitofwork.commit ()
Insert one or two related lists. There is an error in the list, and the entire transaction is rolled back. Use of the reponsitory of the iunitofwork.
List<bl_invoice> Invoicelst =NewList<bl_invoice>(); List<BL_InvoiceDetail> Detaillst =NewList<bl_invoicedetail>(); varLST = invoiceservice.query (m = m.id > the). ToList (); for(intn =0; N < LST. Count (); n++) {Bl_invoice i=NewBl_invoice () {iswd=Lst[n]. ISWD, Isazure=Lst[n]. Isazure, InvoiceNumber=Lst[n]. InvoiceNumber, Invoicedate=DateTime.Now, Bittype=Lst[n]. Bittype, Bpexternalid=Lst[n]. Bpexternalid, Caexternalid=Lst[n]. Caexternalid, Amount=Lst[n]. Amount, ismethodsynced=false, METHOD_INCC= (n==1)?"XXX":"P", CreatedDate=DateTime.Now}; Invoicelst.add (i); varinvoicedetailoriginal = invoicedetailservice.query (m = M.detailid = = the). FirstOrDefault ();//Lst[n]. Bl_invoicedetail.firstordefault ();Bl_invoicedetail d =NewBl_invoicedetail () {Bl_invoice=I, BITREF32=Invoicedetailoriginal.bitref32, Mssku= (n = =1) ?"Save 20 Chinese characters, save 20 characters, save 20 Chinese characters, save 20 Chinese characters, and save 20 Chinese characters. ": Invoicedetailoriginal.mssku, Amount=Invoicedetailoriginal.amount, tax=Invoicedetailoriginal.tax, Deferralamount=Invoicedetailoriginal.deferralamount, Bitdate_from=Invoicedetailoriginal.bitdate_from, Bitdate_to=invoicedetailoriginal.bitdate_to, CreatedDate=DateTime.Now}; Detaillst.add (d); } invoiceservice.addrange (Invoicelst, detaillst);
In general, database operations in the Entity Framework all reflect the relevance of the transaction, which is also a reasonable requirement. Simpler and easier to operate than ADO.
