 <p>Concatenate them like this:</p> <pre><code>Response.Redirect("Default2.aspx?adi=" + adi + "&amp;soyadi=" + soyadi); </code></pre> <p>When passing query string parameters, use the <code>?</code> symbol just after the name of the page and if you want to add more than one parameter, use the <code>&amp;</code> symbol to separate them</p> <p>In the consuming page:</p> <pre><code> protected void Page_Load(object sender, EventArgs e) { var adi = this.Request.QueryString["adi"]; var soyadi = this.Request.QueryString["soyadi"]; } </code></pre>
