使用 WriteToServer 方法日期时间列插入数据会出现异常

Question

我正在尝试将 DateTime 插入到数据类型为日期时间的列中。该值是使用 DateTime.Now 分配的，因此我知道代码中不存在类型不正确的问题。

我得到的异常是：

The given value of type String from the data source cannot be converted
to type datetime of the specified target column.

这就是我指定数据表列的方式：

DataTable HODetails = new DataTable();
HODetails.Columns.Add("MasterID", typeof(long));
HODetails.Columns.Add("ItemID", typeof(int));
HODetails.Columns.Add("SubCategoryID", typeof(int));
HODetails.Columns.Add("BatchNo", typeof(string));
HODetails.Columns.Add("ExpiryDate", typeof(DateTime));

这是我设置数据的方式：

HODetails.Rows[HODetails.Rows.Count - 1]["ItemID"] = Convert.ToInt32(lblItemId.Text);
HODetails.Rows[HODetails.Rows.Count - 1]["MasterID"] =HOReceipt_ID;
HODetails.Rows[HODetails.Rows.Count - 1]["SubCategoryID"] = SubCatID;
HODetails.Rows[HODetails.Rows.Count - 1]["BatchNo"] = Convert.ToString(txtBatchNo.Text == "" ? "" : txtBatchNo.Text);
HODetails.Rows[HODetails.Rows.Count - 1]["ExpiryDate"] = DateTime.Now;

那么为什么 WriteToServer() 认为 "value of type String from the data source cannot be converted to type datetime"？

我的问题解决了我更改了我的 writeToServer 方法

                if (DtWithTableName.Rows.Count > 0)
                {
                using (SqlBulkCopy s = new SqlBulkCopy(strConnection))
                {

                try
                {
                    s.DestinationTableName = "HOMaterialReceiptDetails";
                    s.ColumnMappings.Add("MasterID", "MasterID");
                    s.ColumnMappings.Add("ItemID", "ItemID");
                    s.ColumnMappings.Add("SubCategoryID", "SubCategoryID");
                    s.ColumnMappings.Add("ExpiryDate", "ExpiryDate");
                    s.ColumnMappings.Add("BrandName", "BrandName");
                    s.ColumnMappings.Add("Qty", "Qty");
                    s.ColumnMappings.Add("FreeQty", "FreeQty");
                    s.ColumnMappings.Add("ReturnQty", "ReturnQty");
                    s.ColumnMappings.Add("ReplacementQty", "ReplacementQty");
                    s.WriteToServer(DtWithTableName);
                }
                catch (Exception)
                {

                    IsInserted = false;
                }

            }
        }

使用 WriteToServer 方法日期时间列插入数据会出现异常

insert data using WriteToServer method datetime column gives exception

c#

sql-server

datetime

sqlbulkcopy
