InvalidOperationException: Sequence contains more than one element

I have the following code below for a payroll program. The first dictionary holds the employee IDs and corresponding basic pays held in a master data table. The second dictionary holds the employee IDs and corresponding basic pays held in a salary fitment table – used for processing. I want to update the salary fitment basic pays for each employee ID that do not match in the master table. (Changes in salary).

var OHEMDictionary = employees.OrderBy(es => es.empID) .ToDictionary(od => od.empID, od => od.salary); var SalaryFitmentDictionary = salaryFitments .Where(x => x.U_PD_Code.Trim().ToString() == “SYS001”) .OrderBy(es => es.U_Employee_ID) .ToDictionary(od => od.U_Employee_ID, od => od.U_PD_Amount); var difference = OHEMDictionary .Where(kv => SalaryFitmentDictionary[kv.Key] != kv.Value); difference.ToList().ForEach(x => { decimal salary = x.Value.Value; var codeToUpdate = salaryFitments .Where(y => y.U_Employee_ID.Equals(x.Key)) .Select(z => z.Code) .SingleOrDefault(); `**<---exception thrown here**` var salaryFitment = salaryFitmentService .GetSalaryFitment(codeToUpdate); if (salaryFitment != null) { // Save record salaryFitmentService .UpdateSalaryFitment(salaryFitment, salary.ToString()); } });

[Solved]Exception: Sequence contains more than one element in Asp.net Core

Exception: Sequence contains more than one element in Asp.net Core

Dung Do Tien Oct 02 2021 329

Hello, I have a project with Asp.Net Core 3.1 and I created a function to get list of articles by brand and model as below:

public ArticleBrandModel GetArticleByBrandModel(int id) { try { var result = QuerySP(“func_fe_getbrandmodelbyarticleid”, new { _id = id }); return result.SingleOrDefault() ?? new ArticleBrandModel(); } catch (Exception ex) { Logger.Error(ex, ex.Message); return new ArticleBrandModel(); } }

But when I call this method I get an exception throw System.InvalidOperationException: Sequence contains more than one element. You can see detail exception below:

System.InvalidOperationException: Sequence contains more than one element at System.Linq.ThrowHelper.ThrowMoreThanOneElementException() at System.Linq.Enumerable.SingleOrDefault[TSource](IEnumerable`1 source) at APS.AP.Application.News.Stograge.Daoes.Impl.CarNewsDao.GetArticleBrandModel(Int32 id) in /src/Application/APS.AP.Application.News/Stograge/Daoes/Impl/CarNewsDao.cs:line 126″

I using PostgreSql database and PostgreHelper to help connect to database.

I tried debug and execute postgre function but it work well for me.

How can I resolve this issue?

Thanks for any suggestions.
