Hi There,

I have two forms, each with a public datatable declared in them. To spare you the details of why, I want to know how I can compare the two datatables to see if they are equal.

I need to know that all data in each datatable is exactly the same. I have tried the following, but to now avail:
VB.NET:
if form1.datatable.tostring = form2.datatable.tostring then
the problem with this is that it is true for all datatables, even when they are not the same.
and...
VB.NET:
if form1.datatable.select is form2.datatable.select then
but this is false for all datatables, even when they are the same.

How can I successfully compare two datables to define whether they are equal or not?

I can't use:
VB.NET:
if form1.datatable = form2.datatable then
because it says that you can't compare reference types in this way, and, I can't use:
VB.NET:
if form1.datatable is form2.datatable then
because it is false for every datatable even when they are the same.


Please response asap, your help with this will be much appreciated!


Thanks,
Michelle
