我正在尝试根据会员的付款更新贷款余额。 付款顺利,按预期插入,但在更新表LOANBAl期间,没有任何修改,下面是我的代码:
public void UpdateLoanBal(MPAreceipting mpa, string id)
{
using (BOSAEntities db = new BOSAEntities())
{
General gn = new General();
gn.GetUser();
gn.GetServerDate();
LoanRepayment lr = new LoanRepayment();
lr.GetMemberDeduction(loanno);
var lOANBAL = db.LOANBALs.Find(id);
var lb = new LOANBAL();
lb.AuditID = gn.sysUser;
lb.AuditTime = gn.serverDate;
lb.Balance = Convert.ToDecimal(lr.loanBalance);
lb.IntrOwed = Convert.ToDecimal(lr.intOwed);
lb.LastDate = mpa.dateDeposited;
db.Entry(lOANBAL).State = EntityState.Modified;
db.SaveChanges();
}
}
答案 0 :(得分:1)
我使用了lOANBAL这是一个实体并更新了它的属性。
public void UpdateLoanBal(MPAreceipting mpa, string id)
{
var db = new BOSAEntities();
using (var dbContextTransaction = db.Database.BeginTransaction())
{
try
{
var lOANBAL = db.LOANBALs.Find(loanno);
General gn = new General();
gn.GetUser();
gn.GetServerDate();
LoanRepayment lr = new LoanRepayment();
lr.GetMemberDeduction(loanno);
lOANBAL.LoanNo = loanno;
lOANBAL.AuditID = gn.sysUser;
lOANBAL.AuditTime = gn.serverDate;
lOANBAL.Balance = Convert.ToDecimal(lr.loanBalance);
lOANBAL.IntrOwed = Convert.ToDecimal(lr.intOwed);
lOANBAL.LastDate = mpa.dateDeposited;
lOANBAL.TransactionNo=lr.
db.Entry(lOANBAL).State = EntityState.Modified;
db.SaveChanges();
dbContextTransaction.Commit();
}
catch (DbEntityValidationException Exc)
{
dbContextTransaction.Rollback();
string errormessage = string.Join(";",
Exc.EntityValidationErrors.SelectMany(x => x.ValidationErrors).Select(x => x.ErrorMessage));
throw new DbEntityValidationException(errormessage);
}
}
}
