推荐答案

尝试阅读一些内容.

Try reading a bit. Google is your friend

1,640,000 results... Try something. If you have issues at that point, ask something more specific. (i.e. Make an effort, please)

假设您有一个名为tbl的表，该表已被填充并具有行:

Assume you have a table called tbl that has been filled and has rows:

Random rndm = new Random();
DataRow rndm_row;

foreach(DataRow row in tbl.Rows)
{

     rndm_row = tbl.Rows[rndm.Next(0,tbl.Rows.Count - 1)];

     // Do something with rndm_row

}

出于好奇，您为什么要这么做?

Out of curiousity, why would you want to do that?
