Introduction
Most of the time our clients
need to use their email contacts from their application, they believe in the
good application which reduces their effort to go other websites, they know
everything can not be possible to implement but not impossible, so here
requirement comes to implement a section to import contacts from Gmail and send
email to the selected email id from the asp.net application.
A good application is one who can complete your all or
maximum work from one browser window or from one application.
I tried here to describe "Import Gmail contacts in
ASP.NET". Hope I'll explain it here in a better way so that everyone facing
this issue can done this like the way I done.
Requirement
We all know while the
implementation of any third party tool in ASP.net we need concerned dlls to add
references in the application.
To import Gmail contacts in ASP.NET application we need to
download "Google API setup" from the below link
Download
Google API setup
This link I'll download following dll’s in to your PC :
- Google.GData.Apps.dll
- Google.GData.Client.dll
- Google.GData.Contacts.dll
- Google.GData.Extensions.dll
When you got these dll’s on your PC we need to add these to
our application.
Add references in to your application by right click ->
add reference ->Browse dll’s -> OK
Source Code
Add below source code to create a design like I created :
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Import gmail contacts in to asp.net | Neha Sharma</title>
<style type="text/css">
.auto-style1 {
height: 26px;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div>
<table align="center" style="height: 104px; width: 301px; background-color: #F0F0F0">
<tr>
<td>
Gmail ID</td>
<td>
<asp:TextBox ID="txtgmailusername" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td class="auto-style1">
Password</td>
<td class="auto-style1">
<asp:TextBox ID="txtpassword" runat="server" TextMode="Password"></asp:TextBox>
</td>
</tr>
<tr>
<td>
<asp:Button ID="Button1" runat="server" Text="Get" OnClick="Button1_Click" />
</td>
<td>
</td>
</tr>
<tr>
<td colspan="2">
You have below contacts in Gmail ID</td>
</tr>
<tr>
<td colspan="2">
<asp:GridView ID="gridemails" runat="server">
<EmptyDataTemplate>
You dont have any contacts yet.
</EmptyDataTemplate>
</asp:GridView>
</td>
</tr>
</table>
</div>
<div>
<%--<asp:DropDownList ID="ddlemails" runat="server"></asp:DropDownList>--%>
</div>
</form>
</body>
</html>
Code behind :
Add the following namespaces first:
using Google.GData.Contacts;
using Google.GData.Client;
using Google.GData.Extensions;
using Google.Contacts;
using System.Data;
using System.Data.SqlClient;
Now,
public partial class Default3 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
public DataSet GetGmailContacts(string p_name, string e_id, string psw)
{
DataSet ds = new DataSet();
DataTable dt = new DataTable();
DataColumn dc = new DataColumn();
dc.DataType = Type.GetType("System.String");
dc.ColumnName = "emailid";
dt.Columns.Add(dc);
RequestSettings rs = new RequestSettings(p_name, e_id, psw);
rs.AutoPaging = true;
ContactsRequest cr = new ContactsRequest(rs);
Feed<Contact> f = cr.GetContacts();
foreach (Contact t in f.Entries)
{
foreach (EMail email in t.Emails)
{
DataRow dr1 = dt.NewRow();
dr1["emailid"] = email.Address.ToString();
dt.Rows.Add(dr1);
}
}
ds.Tables.Add(dt);
return ds;
}
public void getcontacts()
{
DataSet ds = GetGmailContacts("MyNetwork Web Application!", txtgmailusername.Text, txtpassword.Text);
gridemails.DataSource = ds;
gridemails.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
getcontacts();
}
}
Save the whole work and run the
page.
