Hi Try like this Using normal loop private void button1_Click(object sender EventArgs e) { char[] array1 = new char[5] { 'a' 'b' 'c' 'd' 'e' }; char[] array2 = new char[3] { 'x' 'b' 'd' }; string data = string.Empty; for (int i = 0; i { char chr = array2[i]; if (array1.Contains(chr)) { data = data + chr.ToString(); } } textBox1.Text = data; } Using Linq private void button1_Click(object sender EventArgs e) { char[] array1 = new char[5] { 'a' 'b' 'c' 'd' 'e' }; char[] array2 = new char[3] { 'x' 'b' 'd' }; string data = string.Empty; var result = from s in array1 where array2.Contains(s) select s; foreach (var chr in result) { data = data + chr.ToString(); } textBox1.Text = data; } Regards Iftikar

Try this replace your values... char[] abc = new char[9] { '1' '2' '3' '4' '5' '6' '7' '8' '9' }; char[] xyz = new char[5] { '1' '2' '3' '4' '5' }; List query =(from p in abc where xyz.Contains(p) select p).ToList();

thx u Ravi & Hussain.... but I don't get it what u mean... here is what I want... Form1 has 30 textboxes which are stored 'char' values. Form2 has only one textbox which is stored 'string' value. For example; char[] abc = new char[30] {'a' 'b' 'c' 'd' 'e' 'f' 'g' 'h' 'i' 'j' 'k'......'z'}; // from Form1 string xyz = apple; // from Form2 each character in the word apple is need to check whether is equal to one of the character in the array char[] abc. if they are matched each other..... I want to show the results in another textbox..
