two string array matching in c sharp

Hi friend,

By the below coding you can get unique string from array a.

 string[] a = new string[] { "a","b","c","d" };
 string[] b = new string[] { "a","f","c","d" };

for (int i = 0; i < a.Length ; i++)
            {
                for (int j = 0; j < b.Length ; j++)
                {
                    if (i != j)
                    {
                        if (a[i] == a[j])
                        {
                            a[i] = "";
                            j = j + 4;
                        }
                    }
                    if (a[i] == b[j])
                    {
                        a[i] = "";
                        j = j + 4;
                    }

                }
               
            }
