add reference od system.text.regularexpression

and then use this code: 

private void txtEmail_Leave(object sender, EventArgs e)

        {

            Regex mRegxExpression;

            if (txtEmail.Text.Trim() != string.Empty)

            {

                mRegxExpression = new Regex(@"^([a-zA-Z0-9_\-])([a-zA-Z0-9_\-\.]*)@(\[((25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9])\.){3}|((([a-zA-Z0-9\-]+)\.)+))([a-zA-Z]{2,}|(25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9])\])$");

                if (!mRegxExpression.IsMatch(txtEmail.Text.Trim()))

                {

                    MessageBox.Show("E-mail address format is not correct.", "MojoCRM", MessageBoxButtons.OK, MessageBoxIcon.Error);
