在我的asp.net核心代码中，我在验证中使用了ModelState.AddModelError（），并且它导致多线程并且代码将重复记录插入到表中。有没有办法来防止这个问题？谢谢。使用导致多线程和重复记录的ModelState.AddModelError插入
控制器：
public IActionResult BudgetAdd(BudgetDocumentAddViewModel model)
{
if ((model.ACCT.Length < 6) || (((model.FUND == "508") || (model.FUND == "760") || (model.FUND == "761")) && (model.ACCT.Substring(0, 2) != "50")))
{
ModelState.AddModelError("ACCT", "Error: Incorrect Account (ACCT) Number!!!");
}
if (ModelState.IsValid)
{
var document = new tDocument();
document.FY = model.FY;
document.FUND = model.FUND;
document.AUTH = model.AUTH;
document.DEPT = model.DEPT;
document.DOCU_TYPE = model.DOCU_TYPE;
//Need to get the largest DOCU_ID. Cannot rely on the DOCU_ID from the form.
//document.DOCU_ID = model.DOCU_ID;
document.DOCU_ID = _docManager.GetDocuID(model.FY, model.FUND, model.AUTH, model.DEPT, model.DOCU_TYPE);
document.ENT_DT = model.ENT_DT;
document.BUD_YR = model.BUD_YR;
document.ORG = model.ORG;
document.ACCT = model.ACCT;
document.DOCU_DT = model.DOCU_DT;
if (model.DEPT_OBJ.Length >= 3)
{
document.OBJ = (model.DEPT_OBJ).Substring(0, 3);
if (model.DEPT_OBJ.Length == 5)
{
document.SUB_OBJ = (model.DEPT_OBJ).Substring(3, 2);
}
}
else
{
document.OBJ = "";
document.SUB_OBJ = "";
}
document.DESP = model.DESP;
//document.AMOUNT = model.AMOUNT.ToString().Replace(",", string.Empty);
var sAmount = model.AMOUNT.ToString();
sAmount = sAmount.Replace(",", string.Empty);
document.AMOUNT = Decimal.Parse(sAmount);
document.RECV_DT = model.RECV_DT;
document.OUT_DT = model.OUT_DT;
if (model.FUND == "100" && model.ACCT == "002120")
{
document.OBJ = "212";
}
if (model.FUND == "100" && model.ACCT == "002130")
{
document.OBJ = "213";
}
if (model.FUND == "100" && model.ACCT == "003030")
{
document.OBJ = "605";
}
if (model.FUND == "100" && model.ACCT == "003040")
{
document.OBJ = "304";
}
if (model.FUND == "100" && model.ACCT == "003090")
{
document.OBJ = "609";
}
if (model.FUND == "100" && model.ACCT == "004430")
{
document.OBJ = "607";
}
if (model.FUND == "100" && model.ACCT == "006010")
{
document.OBJ = "601";
}
if (model.FUND == "100" && model.ACCT == "006020")
{
document.OBJ = "602";
}
if (model.FUND == "100" && model.ACCT == "007300")
{
document.OBJ = "730";
}
//To get the username from the AspNetUsers table and assign it to the User_ID field in the tDocuments table.
document.USER_ID = User.Identity.Name.ToString();
_docManager.AddDocument(document);
return RedirectToAction("BudgetSearch", "Document", new { FY = document.FY, FUND = document.FUND, DEPT = document.DEPT, AUTH = document.AUTH });
}
model.Divisions = _docManager.GetOrganizations();
return View(model);
}

每次运行的代码，它插入相同的记录两次。如果注释掉ModelState.AddModelError（）行，那么它没有任何问题（这意味着它插入一条记录）正常工作。
什么是ACCT？它怎么能<5（数字）并且同时支持'substring'（字符串）？ –
它应该是model.ACCT.Length <5.我尝试通过放入ModelState.IsValid的检查来重新排列代码，但它不起作用。 –
我注意到，当我使用IE11测试应用程序时，发生重复记录。但是，当我使用Firefox进行测试时，重复没有发生。如果仅在特定浏览器中出现重复记录，可能会导致重复记录插入表中。 –
