我创建了一个转换，将数据从CSV文件复制到SQL Server表。由于我的CSV文件是动态的，并且在给定时间可以包含任意数量的列，因此我添加了 ScriptComponent 任务来维护映射b / w 'FlatFileSource'和 'OLEDBDestination'任务。
我现在能够复制数据但是列名称行也被添加为目标表中我不想要的数据行。下面是我在脚本任务中编写的代码，用于读取csv并将行添加到输出缓冲区。

SSIS方面并没有真正改变与StreamReader读取标题有关的任何内容，除非你想对标题行做一些有意义的事情。
只需在循环之前调用sr.ReadLine()（阅读第一行）并对其执行任何操作，如下所示：
...
sr.ReadLine();
while (!sr.EndOfStream)
{
string headline = sr.ReadLine();
if (!string.IsNullOrEmpty(headline))
...
