我想使用准备好的语句将一些数据插入到 SQL Server 数据库中。
我想要的查询是：
INSERT INTO salesdata([OriginalFilename], [InterchangeReceiverID], [Distributor],
[DE_Date], [DE_VendorNR], [DE_VendorDEANR], [DE_VendorName],
[DE_DistributionCenterNR], [DE_DistributionCenterID],
[DE_DistributionCenterName], [DE_ItemNR],[DE_ItemNDCNR], [DE_ProductUOM],
[DE_CustomerAccountNR], [DE_CustomerDEANR], [DE_CustomerNPINR],
[DE_CustomerHINNR], [DE_CustomerName], [DE_CustomerAddress1],
[DE_CustomerAddress2], [DE_CustomerCity], [DE_CustomerState],
[DE_CustomerZipcode], [DE_CustomerCountry], [DE_InvoiceNR], [DE_Invoicedate],
[DE_QuantitySold], [DE_QuantityReturned], [DE_SalesReturnCode],
[DE_ContractNR], [DE_Price])
VALUES(@OriginalFilename, @InterchangeReceiverID, @Distributor,
@DE_Date, @DE_VendorNR, @DE_VendorDEANR, @DE_VendorName,
@DE_DistributionCenterNR, @DE_DistributionCenterID,
@DE_DistributionCenterName, @DE_ItemNR, @DE_ItemNDCNR, @DE_ProductUOM,
@DE_CustomerAccountNR, @DE_CustomerDEANR, @DE_CustomerNPINR,
@DE_CustomerHINNR, @DE_CustomerName, @DE_CustomerAddress1,
@DE_CustomerAddress2, @DE_CustomerCity, @DE_CustomerState,
@DE_CustomerZipcode, @DE_CustomerCountry, @DE_InvoiceNR, @DE_Invoicedate,
@DE_QuantitySold, @DE_QuantityReturned, @DE_SalesReturnCode,
@DE_ContractNR, @DE_Price)
我像这样遍历所有参数：
command.Parameters.Add(new SqlParameter("@InterchangeReceiverID", SqlDbType.NVarChar,500));
command.Parameters["@InterchangeReceiverID"].Value = "VALUEGOESHERE";
我也尝试了该Parameters.Add(name,value)方法，但已弃用。
我不断收到的错误是：
System.InvalidOperationException：SqlCommand.Prepare 方法要求所有参数都具有明确设置的类型。
不幸的是，他没有提到导致问题的参数。我正在使用大小为 500 的 NVarchar 和大小为 18 且比例为 6 的小数。
我做错了什么，或者我怎样才能找出导致问题的参数？我将所有参数写入文件（带有大小/比例和值），所有参数看起来都很好......
