Когда я пытаюсь найти запись по имени поля uuid
Я получаю сообщение об ошибке ниже:
{Входная строка была в неправильном формате.}
Еще примечание: Кажется, разбор ENUM из MySQL - большая проблема в c #
, он работал без ошибок, когда я изменил
public BankAccountReconciled? Reconciled { get; set; }
на:
public string Reconciled { get; set; }
Теперь мне нужнознать, как дать команду Linq для анализа Enum из Mysql обратно в C # Enum:
public enum BankAccountReconciled
{
[Display(Name = "true")]
True,
[Display(Name = "false")]
False
}
Ошибка при Try / Catch:
{"Input string was not in a correct format."}
- e {"Input string was not in a correct format."} System.Exception {System.FormatException}
Когда нажимают SHIFT + f9 и оценивают I 'm приведенная ниже ошибка:
"Method System.Data.Entity.Core.Objects.ObjectQuery`1[T] MergeAs(System.Data.Entity.Core.Objects.MergeOption) contains generic parameters"
public XeroBankAccount FindAccountByUuid(String uuid)

using (SyncBankDbContext dbContext = new SyncBankDbContext())
{
string tempUuid = uuid;
var result = dbContext.XeroBankAccounts.SingleOrDefault(x => x.AccountUuid == tempUuid);
return result;
}
}
catch (Exception e)

string errorMessage = e.Message;
