Question

My WCF service function return type is Dictionary(Of String, String). So I have to convert my Dataset to Dictionary.

Here is my dataset example.

Account AccountNames

abc abc1

abc abc2

abc abc3

xyz xyz1

xyz xyz2

xyz xyz3

xyz xyz4

pqr pqr1

pqr pqr2

pqr pqr3

pqr pqr4

pqr pqr5

pqr pqr6

Using LINQ or without LINQ, How can I convert Dataset To Dictionary(Of String, String)

Answer 1

Assuming the 2nd column are the keys you can do this:

Dim ds As DataSet = someValueHere
Dim dc As New Dictionary(Of String, String)
For Each r As DataRow In ds.Tables(0).Rows
     dc.Add(r.Item(1).ToString(), r.Item(0).ToString())
Next

I don’t know if there will be a shortcut for linq.
Note: dictionary cannot contain duplicate keys, so if the 1st column corresponds the key and the 2nd column for the values, it is not possible.
