この 2 つのメソッドを 1 つのビューに渡したい:
public IEnumerable<ProfitAndCostViewModel> getProfitSum()
{
var profBalance = db.Profits
.Where(x => x.IdUser.UserId == WebSecurity.CurrentUserId)
.GroupBy(x => x.IdUser.UserId)
.Select(x => new ProfitAndCostViewModel { ProfitSum = x.Sum(y => y.Value) })
.ToList();
return profBalance;
}
public IEnumerable<ProfitAndCostViewModel> getCostSum()
{
var costBalance = db.Costs
.Where(x => x.IdUser.UserId == WebSecurity.CurrentUserId)
.GroupBy(x => x.IdUser.UserId)
.Select(x => new ProfitAndCostViewModel { CostSum = x.Sum(y => y.Value) })
.ToList();
return costBalance;
}
私のActionResultで私はこれを持っています:
var pcv = new ProfitAndCostViewModel();
pcv.ProfModel =getProfitSum();
pcv.CostModel =getCostSum();
return View(pcv);
ProfitAndCostViewModel のコードは次のとおりです。
public double ProfitSum { get; set; }
public double CostSum { get; set; }
public double FinalBalance { get; set; }
public IEnumerable<ProfitAndCostViewModel> ProfModel { get; set; }
public IEnumerable<ProfitAndCostViewModel> CostModel { get; set; }
これはエラーです: The model item passed into the dictionary is of type 'WHFM.ViewModels.ProfitAndCostViewModel', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable
1[WHFM.ViewModels.ProfitAndCostViewModel]'.`
