Question

这是C＃Winforms。

我在这段代码中有一个字符串列表：

List<string> WaveAndPickFields = new List<string>(new string[] { "ID", "TransactionID", "OrderNumber", "WarehouseID", "StoreOrderNumber", "OrderType", "CustomerID", "CustomerPONumber", "DepartmentCode", "LoadNumber", "ReverseLoadSequence", "BOLNumber", "MasterBOLNumber", "ProNumber", "Carrier", "CarrierSCAC", "FreightTerms", "RushOrderFlag", "OrderEntryDate", "ExpectedCarrierArrivalDate", "DatePromised", "OrderWeight", "OrderCubicVolume", "OrderCartonCounts", "ShippingShort", "PrepaidFreight", "CODAmount", "InsuranceAmount", "PIPAmount", "TotalFreightCost", "ShipToCustomerCode", "ShipToName", "ShipToAddress1", "ShipToAddress2", "ShipToAddress3", "ShipToCity", "ShipToState", "ShipToZipCode", "ShipToCountryCode", "ShipToCountryName", "BillToCustomerCode", "BillToName", "BillToAddress1", "BillToAddress2", "BillToAddress3", "BillToCity", "BillToState", "BillToZipCode", "BillToCountryCode", "BillToCountryName", "DeliveryAddressName", "DeliveryAddress1", "DeliveryAddress2", "DeliveryAddress3", "DeliveryCity", "DeliveryState", "DeliveryZipCode", "DeliveryCountryCode", "DeliveryCountryName", "DeliveryPhone", "BillFreightCustomerCode", "BillFreightAddressName", "BillFreightAddress1", "BillFreightAddress2", "BillFreightAddress3", "BillFreightCity", "BillFreightState", "BillFreightZipCode", "BillFreightCountryCode", "BillFreightCountryName", "CartonLabel", "ShipVerificationFlag", "PartialOrderFlag", "EarliestShipDate", "LatestShipDate", "EarliestDeliveryDate", "LatestDeliveryDate", "PromoCode", "Route", "Stop", "ToteFlag", "Status" });

我想做的就是遍历这段代码并将一堆字段添加到数据表中。我在这段代码中这样做：

foreach (string field in WaveAndPickFields)
{
    dtWaveAndPicks.Columns.Add(field);
}

我也尝试过：

for (int i = 0; i < WaveAndPickFields.Count; i++)
{
    DataColumn column = new DataColumn(WaveAndPickFields[i]);
    dtWaveAndPicks.Columns.Add(column);
}

无论出于何种原因，这些行似乎都会执行，但整个函数会停止，没有其他任何事情都会执行而没有异常错误。

dtWaveAndPicks.Columns.Add(field);

和

dtWaveAndPicks.Columns.Add(column);

有谁知道为什么会这样？对我有用的替代方法是使用一行添加一列。问题是，当我有这样的循环时，我不想要有80多行来添加字段。

我强烈建议使用windbg来确定这里发生了什么 - 如果你没有使用它之前它有点令人生畏但是有很好的教程（特别是来自Tess see here）

安装windbg后，在挂起时通过任务管理器获取进程转储在windbg中打开转储文件

然后运行.symfix c:\sos以修复符号路径

下一步加载sos .loadby sos mscorwks

最后检查任何线程运行.foreach (ex {!dumpheap -type Exception -short}){.echo "********************************";!pe –nested ${ex} }

上的异常

试试这个＆amp;看看你如何上场

代码停止执行没有明显的原因
