Lets' say I pull data from a sql server table into a local data table
fld1 fld2 fld3
a1 a2 a3
b1 b2 b3
c1 c2 c3
Here is the data content from my array
a1 a2 a3
b1 b2 b3
c1 c2 c3
I want to compare the two data sets against each other (all string content) to see if they contain the same data. I was thinking I may want to add these contents to List1 and List2 and compare the lists -- or would it be better to add the contents to a couple of string vars? If this is a good approach then I have 2 questions:
1) Do I need to loop through each dataset (loop through the rows in the table and the rows in the array) and add the strings to a list or string vars or is there Linq that can do this?
2) what is the correct way to compare 2 such lists? Does List1 = List2? or str1 = str2
If this approach is not the ideal approach I would be grateful for suggestions of a better way, otherwise, I would be grateful if someone could share a good technique for creating/comparing some structure for comparing the contents from these datasets.
Thanks in advance
