I have 2 forms.
for example, One form has 30 textboxes which fill up with one char and another form has only one textbox which fill up with one word(5 char).
i make 2 arrays. 30 indexes of array1 and 5 indexes of array2.
i want to show the result characters in another textbox when each index of array2 is equal to each index of array1.
how to write the function()?

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 < array2.Length; 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;
}

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..

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();
