Comparing two data tables
- Thread starter zrefugee
- Start date
What do you mean "comparing" tables? compare data?
In general, all objects have a method called "equals", but a table is a reference type, so equals returns true only if both references refer to the same object, and I assume this is not what you are looking for.
I don't think there is a function that does it.
You need to write it yourself, but you can make a table class that inherit from DataTable and override the equals method as you wish so your code will lokk nice (Don't forget to override the GetHashCode method).
If you want a challenge, make a general equals method that uses reflection to get all members of an instance and compare them to another instace members, but I don't think it worth.
