C# 输入字符串的格式不正确

Question

我在运行以下代码时有时会收到 FormatException 错误。异常似乎是随机抛出的。我的团队成员在运行代码时看到了错误，并会通知我。在几秒钟内，我将尝试使用相同的应用程序插入相同的数据，而不是让它出现异常。我在下面附上了格式异常文本的示例。异常意味着我正在尝试将小数转换为 int32，但在我分配的以下值中，没有一个是小数或 int。有没有人遇到过这样的格式异常？

foreach (var strPriceFile in lstPriceFiles)
{
    var SoldToRecs = DbContext.RFQ_SoldTo_PriceLists.Where(us => us.UserId == ERepGuid && us.RFQ_SoldTo_CustNbr == strSoldTo[0] && us.RFQ_SoldTo_CustSeq == strSoldTo[1] && us.IngresFileName == strPriceFile);

    if (SoldToRecs.Count() == 0)
    {
        var PriceFile = new RFQ_SoldTo_PriceList();
        PriceFile.UserId = ERepGuid;
        PriceFile.RFQ_SoldTo_CustNbr = strSoldTo[0];
        PriceFile.RFQ_SoldTo_CustSeq = strSoldTo[1];
        PriceFile.IngresFileName = strPriceFile;
        PriceFile.CreatedBy_UserName = strCreatorName;
        PriceFile.CreatedBy_DateTime = DateTime.Now;
        PriceFile.Active_YN = true;

        DbContext.RFQ_SoldTo_PriceLists.InsertOnSubmit(PriceFile);
    }
}

只要您使用 RadScheduler、RadListBox 和 RadTreeView，您的问题可能是由 Google Chrome 放大/缩小问题引起的，如 Hristo Valyavicharski 在下面的链接。在这种情况下，您可以通过放大或缩小 Google Chrome 并再次执行回发来重现此问题。

以下是 Hristo Valyavicharski 提供的修复:

对于 RadScheduler:

<script type="text/javascript">
Telerik.Web.UI.RadScheduler.prototype.saveClientState = function () {
    return '{"scrollTop":' + Math.round(this._scrollTop) + ',
    "scrollLeft":' + Math.round(this._scrollLeft) + ',
    "isDirty":' + this._isDirty + '}';
} </script>

对于 RadTreeView:

<script type="text/javascript">
Telerik.Web.UI.RadTreeView.prototype.saveClientState = function () {
    return "{\"expandedNodes\":" + this._expandedNodesJson +
    ",\"collapsedNodes\":" + this._collapsedNodesJson +
    ",\"logEntries\":" + this._logEntriesJson +
    ",\"selectedNodes\":" + this._selectedNodesJson +
    ",\"checkedNodes\":" + this._checkedNodesJson +
    ",\"scrollPosition\":" + Math.round(this._scrollPosition) + "}";
} </script>

对于 RadListBox:

<script type="text/javascript">
    Telerik.Web.UI.RadListBox.prototype.saveClientState = function() {
        return "{" +
                    "\"isEnabled\":" + this._enabled +
                    ",\"logEntries\":" + this._logEntriesJson +
                   ",\"selectedIndices\":" + this._selectedIndicesJson +
                   ",\"checkedIndices\":" + this._checkedIndicesJson +
                   ",\"scrollPosition\":" + Math.round(this._scrollPosition) +
               "}";
    } </script>

希望这对您有所帮助。
