推荐答案

好.

因为您说没有错误，所以我查看了您的代码.注意到一件事:
您可以:

Ok.

I looked at your code since you said no error. Noticed one thing:
You do:

Report.SetDataSource(ds)

但是，ds从未填充.
相反，dt是:

Though, ds was never populated.
Instead, dt was:

da.Fill(dt)

因此，请对其进行更改并尝试以下操作:

So, change it and try something like:

Report.SetDataSource(dt)

看看，是否有帮助.

See, if it helps.
