兩個(gè)數(shù)組比較，去掉重復(fù)的數(shù)據(jù)后生成第三個(gè)數(shù)組，這個(gè)怎么實(shí)現(xiàn)？

.NET

string arr1 ["11","33","2","5555","9999"]string arr2 ["11","9999"]比較這兩個(gè)數(shù)組，得到第三個(gè)數(shù)組（去掉兩個(gè)數(shù)組中的重復(fù)數(shù)據(jù)）的結(jié)果是arr3["33","2","5555"]那么要得到第三個(gè)數(shù)組應(yīng)該怎么實(shí)現(xiàn)呢？

string[] arr1={"11","33","2","5555","9999","10"};
            string[] arr2={"11","9999","1","2"};
            List<string> arr=new List<string>();
            foreach(string c1 in arr1)

            foreach (string c2 in arr2)

                if (!arr1.Contains(c2))
