Compare values from two datasets

[Ondrej Sevecek]

Hello,
I would like to compare two values in different datasets with no previous
knowledge of their type nor format...

dataset1.Tables[5].Rows[10]["CollumnName"] = =
dataset2.Tables[3].Rows[8]["OtherCollumn"]

Ondra.

Will this suffice for your purposes

dataset1.Tables[5].Rows[10]["ColumnName"].equals(dataset2.Tables[3].Rows[8]["OtherColumn"])

I thought that Equals() compares object pointer values, not contents of the
field, doesn't it?

dataset1.Tables[5].Rows[10]["ColumnName"].equals(dataset2.Tables[3].Rows[8][
"OtherColumn"])

I don't think so. I believe Equals() is something that can actually be overridden so that each object can define its own implementation of Equals().

I just ran a test where I filled two different DataSets with the same query from the database, and the following expression retruns true:

dataSet1.Tables[0].Rows[0]["TestTableID"].Equals(dataSet2.Tables[0].Rows[0]["TestTableID"])

Hi,

Equals should do the same as == operator.
Excerpt from help:
a.. Override the Equals method whenever you implement ==, and make them do
the same thing. This allows infrastructure code such as Hashtable and
ArrayList, which use the Equals method, to behave the same way as user code
written using ==.
