Hello all,

I am trying to merge 2 datatables into one. I do not want the merge the second datatable to the below of the first one. I need them to be side by side. I have tried;

C#

dtAll = dt1.Copy();
dtAll = dt2.Merge(); // This adds the dt2 below

After googling, I have found that site[^].Is there a better way to solve this?
Thanks in advance.

We can't really answer that.
The problem is that we don't know how the two tables are interrelated: or even if they are!

If you have two tables which have a common element - a UserID say - then you need to merge them into a new table so that a row in TableA with UserID 1234 is combined with the row from TableB where it's UserID is also 1234 and so forth. If there is no such element, then the two sets of information are not interdependent and probably shouldn't be combined anyway.

And if you do have such a relationship, then you are probably better filling a single table from your datasource in the first place!

I think you need to re-think your problem in terms of "why am I trying to do this?" before you continue any further.

Solution 2

dtAll = dt1.Copy();

dtAll.Merge(dt2);
