In a method I am using following code.
string[] Array1 =newstring[] {"Orange","Mango","welcome","power","Street","Visual"};
string[] Array2 =newstring[] {"Orange","Mango","welcome"};
string[] Array3 =newstring[] {"Orange","Mango", "power","Street" };
string[] Array4 =newstring[] {"Orange","welcome","power","Street" };
I have total 4 arrays some items are repeating in the array. I want to take only the common items from all the array.
What is the best technique to improve the performance.
