可能重复:
SQLBulkCopy的任何方式"插入或更新,如果存在"？

我SQLBulkCopy用来插入批量记录

如何对已存在的记录执行更新(而不是插入)？这有可能SQLBulkCopy吗？

这是我的SQLBulkCopy代码

using (var bulkCopy = new SqlBulkCopy(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString, SqlBulkCopyOptions.KeepNulls & SqlBulkCopyOptions.KeepIdentity))
{
    bulkCopy.BatchSize = CustomerList.Count;
    bulkCopy.DestinationTableName = "dbo.tCustomers";
    bulkCopy.ColumnMappings.Clear();
    bulkCopy.ColumnMappings.Add("CustomerID", "CustomerID");
    bulkCopy.ColumnMappings.Add("FirstName", "FirstName");
    bulkCopy.ColumnMappings.Add("LastName", "LastName");
    bulkCopy.ColumnMappings.Add("Address1", "Address1");
    bulkCopy.ColumnMappings.Add("Address2", "Address2");
    bulkCopy.WriteToServer(CustomerList);
}
