There are mainly five types of Set Operators in Linq.
1. Distinct
2. Concat
3. Union
4. Intersect
5. Except
1.Distinct
public void DistinctFunction()
{
int[] seq1 = { 1, 2, 3, 3, 4, 2, 5, 4, 5, 2, 1 };
var distinctValues = seq1.Distinct();
Console.WriteLine("Distinct Values in the array : ");
foreach (var n in distinctValues)
{
Console.WriteLine(n);
}
}
OutputDistinct Values in the array :
1
2
3
4
5
2.Concat
public void ConcatFunction()
{
int[] seq1 = { 1, 2, 3 }, seq2 = { 3, 4, 5 };
var concatValues = seq1.Concat(seq2);
Console.WriteLine("Concatenation of two array : ");
foreach (var n in concatValues)
{
Console.WriteLine(n); }
}
OutputConcatenation of two array :
1
2
3
3
4
5
3.Union
public void UnionFunction()
{
int[] seq1 = { 1, 2, 3 }, seq2 = { 3, 4, 5 };
var unionValues = seq1.Union(seq2);
Console.WriteLine("Union of two array : ");
foreach (var n in unionValues)
{
Console.WriteLine(n);
}
}
Output
Union of two array :
1
2
3
4
5
4.Intersect
public void IntersectFunction()
{
int[] seq1 = { 1, 2, 3 }, seq2 = { 3, 4, 5 };
var unionValues = seq1.Intersect(seq2);
Console.WriteLine("Intersection of two array : ");
f oreach (var n in unionValues)
{
Console.WriteLine(n);
}
}
OutputIntersection of two array :
3
5.Except
public void ExceptFunction()
{
int[] seq1 = { 1, 2, 3 }, seq2 = { 3, 4, 5 };
var unionValues = seq1.Except(seq2);
Console.WriteLine("Applying Except Function on two arrays : ");
foreach (var n in unionValues)
{
Console.WriteLine(n);
}
}
OutputApplying Except Function on two arrays :
1
2
