Here's a small sample

 <asp:TextBox ID="txtPlace" runat="server" Text = "Goregaon"></asp:TextBox>
    <asp:Button ID="btnSearch" runat="server" Text="Search" 
        onclick="btnSearch_Click" />
    <asp:GridView ID="GridView1" runat="server">
    </asp:GridView>

    protected void btnSearch_Click(object sender, EventArgs e)
    {
        DataSet ds = new DataSet();
        string url = "http://maps.google.com/maps/api/geocode/xml?address=" + txtPlace.Text + "&sensor=false";
        System.Net.WebRequest request = System.Net.WebRequest.Create(url);
        using (System.Net.WebResponse response = (System.Net.HttpWebResponse)request.GetResponse())
        {
            using (System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream(), Encoding.UTF8))
            {
                ds.ReadXml(reader);
                GridView1.DataSource = ds.Tables["result"];
                GridView1.DataBind();
            }
        }
    }
