As Vishal said, the 'dynamic' keyword can only be used with .NET Framework 4.0 or later - it can't be used with .NET Framework 2.0.
I'd only use it as a last resort in any case because it's 'late bound' and therefore much slower than normal C# code. It also needs to pull in an additional component known as the Dynamic Language Runtime (or DLR) and so increases the memory footprint of your application.
Using the object type should work fine here:
object value = 'Y'; // or value = 3
if (textBox1.Text == textBox2.Text) {    textBox2.Text = value.ToString(); }
As TextBox.Text is a string property, you either have to call the ToString() method on value or use this little hack:
textBox2.Text = "" + value;

private void button1_Click(object sender, EventArgs e)
{
dynamic value;
if (textBox1.Text == textBox2.Text)
{ textBox2.Text = value; }
}

i try to find these refencees but could no may b this is due to because i am using .net2 frame work or there is other problem

Hello Friend,
yes you can assign integer or char value to a variable in any .net framework
For .Net Framework less than 4.0
you can do this by declaring an object variable
for eg:
object value='Y';
or
object value=10;
In case of .net framework 4.0 you are provided with a new special datatype named dynamic, we can make use of it for dynamically assigning character or integer or any other value to the variable. All you need to  do is declare a dynamic variable.
dynamic value='Y';
or
dynamic value=10;
Hope that solves your issue.
With Regards,
