Question

I am loading three dataset from the database which has

Dataset 1 > Table 1 > 10 rows
Dataset 2 > Table 1 > 3 rows
Dataset 3 > Table 1 > 5 rows

(All dataset has same column name, same datatype) actually they contains the data based on different select condition)
now I want to merge all three dataset into one like this

Dataset 4 > Table 1 > 18 rows

Please help how can I do it

Answer 1

Try the DataSet.Merge Method (DataSet) method. Something like this (not tested):

C#:

dataset1.Merge(dataset2);

DataSet dataset4 = dataset1.Merge(dataset3);

VB.NET:

dataset1.Merge(dataset2)

Dim dataset4 As New DataSet = dataset1.Merge(dataset3)
