使用SqlBulkCopy进行批量数据插入 

 1 Dim dt As DataTable = New DataTable()
 2             dt.Columns.Add("DtCostProductRuleGUID", GetType(Guid))
 3             dt.Columns.Add("RecollectGUID", GetType(Guid))
 4             dt.Columns.Add("ProjCode", GetType(String))
 5             dt.Columns.Add("ProductGUID", GetType(Guid))
 6             dt.Columns.Add("CostCode", GetType(String))
 7             dt.Columns.Add("CostShortName", GetType(String))
 8             dt.Columns.Add("ParentCode", GetType(String))
 9             dt.Columns.Add("CostLevel", GetType(Integer))
10             dt.Columns.Add("IfEndCost", GetType(Integer))
11             dt.Columns.Add("DtCost", GetType(Decimal))
12             dt.Columns.Add("IsAttend", GetType(Integer))
