.NET Core MySqlBulkCopy 批量新增数据
MySqlConnector有个MySqlBulkCopy批量新增数据方法，不过只能用DataTable，需要把list转成DataTable代码如下：MySqlBulkCopy mySqlBulkCopy = new MySqlBulkCopy(conn)
{
DestinationTableName = "userinfo"
};
mySqlBulkCopy.ColumnMappings.AddRange(table.Columns.Cast<DataColumn>().Select(colum => new MySqlBulkCopyColumnMapping { DestinationColumn = colum.ColumnName, SourceOrdinal = colum.Ordinal }).ToList());
mySqlBulkCopy.WriteToServer(table);
