A quick look on Sharepoint object model programs

Here I am going to show you that the actions which we perform normally with UI, those also can be done programmatically, the same thing I am going to show in this post, this post is mainly targeted for beginners those who are new to Sharepoint object model, a quick watch on programs to create sub sites, lists, showing web apps etc.
Creating Sub Site:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWeb myWeb = mySite.OpenWeb();
SPWebCollection myWebCol = myWeb.Webs;
SPWeb mynewweb = myWebCol.Add("Web url", "Web Title", "Web Description", 1033, "STS#0", false, false);
Console.WriteLine("Press any key to continue.....");
Console.ReadLine();
}

Creating List:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWeb myWeb = mySite.OpenWeb();
myWeb.Lists.Add("My New List", "My new list description", myWeb.ListTemplates["Custom List"]);
SPList newList = myWeb.Lists["My New List"];
newList.OnQuickLaunch = true;
newList.Update();
Console.WriteLine("Press any key to continue.....");
Console.ReadLine();
}

Show all top-level sites in a farm

static void Main()        
 {
 foreach (SPWebApplication myWebApp in SPWebService.ContentService.WebApplications)
 {
 foreach (SPSite mySiteCol in myWebApp.Sites)
 {
 try
 {
 Console.WriteLine(mySiteCol.Url);
 }
 catch (Exception e)
 {
 Console.WriteLine(e);
 }                   
 }
 }
 Console.WriteLine("Press any key to continue.....");
 Console.ReadLine();
 }

Show all site collection in web application:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWebApplication myWebApp = mySite.WebApplication;
SPSiteCollection mySiteCol = myWebApp.Sites;
foreach (SPSite SingleSite in mySiteCol)
{
Console.WriteLine(SingleSite.Url.ToString());
}
Console.WriteLine("Press any key to continue.....");
Console.ReadLine();
}

Show all subsites in site collection:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
foreach (SPWeb myWeb in mySite.AllWebs)
{
Console.WriteLine(myWeb.Url.ToString());
}
Console.WriteLine("Press any key to continue.....");
Console.ReadLine();
}

Show all Roles in a site:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWeb myWeb = mySite.OpenWeb();            
foreach (SPRoleDefinition myRoleDef in myWeb.RoleDefinitions)
{
Console.WriteLine(myRoleDef.Name);
}
Console.WriteLine("Press any key to continue.....");
Console.ReadLine();
}

Show all Alerts in a site:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWeb myWeb = mySite.OpenWeb();            
foreach (SPAlert myAlerts in myWeb.Alerts)
{
Console.WriteLine(myAlerts.Title);
}
Console.WriteLine("Press any key to continue.....");
Console.ReadLine();
}

Show all Lists in a site:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWeb myWeb = mySite.OpenWeb();
foreach (SPList myList in myWeb.Lists)
{
Console.WriteLine(myList.Title.ToString());
}
Console.WriteLine("Press any key to continue.....");
Console.ReadLine();
}

Show all List Templates in a site:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWeb myWeb = mySite.OpenWeb();            
foreach (SPListTemplate myListTemplate in myWeb.ListTemplates)
{
Console.WriteLine(myListTemplate.Name);
}
Console.WriteLine("Press any key to continue.....");
Console.ReadLine();
}

Show all Fields in a List:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWeb myWeb = mySite.OpenWeb();
SPList myList = myWeb.Lists["List Name"];
foreach (SPField myField in myList.Fields)
{
Console.WriteLine(myField.InternalName);  
}  
Console.WriteLine("Press any key to continue.....");  
Console.ReadLine();  
}

Show all Items in a List column:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWeb myWeb = mySite.OpenWeb();
SPList myList = myWeb.Lists["List Name"];
SPQuery myQuery = new SPQuery();
myQuery.Query = "";//Your Query
SPListItemCollection myItemCol = myList.GetItems(myQuery);
foreach (SPListItem myListItem in myItemCol)
{
Console.WriteLine(myListItem["Column Name"].ToString());
}
Console.WriteLine("Press any key to continue.....");
Console.ReadLine();
}

Delete all Items from a list:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWeb myWeb = mySite.OpenWeb();
SPList myList=myWeb.Lists["List Name"];
myWeb.AllowUnsafeUpdates = true;
int count = 1;
for (int i = 0; i < myList.ItemCount; i++)
{
SPListItem myListitem = myList.Items[0];                
myListitem.Delete();
Console.WriteLine(count + " item(s) deleted");
count++;
}
myWeb.AllowUnsafeUpdates = false;
Console.WriteLine("Press any key to continue.....");
Console.ReadLine();
}

Show all Groups in a site:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWeb myWeb = mySite.OpenWeb();
foreach (SPGroup myGroup in myWeb.Groups)  
{  
Console.WriteLine(myGroup.Name);  
}  
Console.WriteLine("Press any key to continue.....");  
Console.ReadLine();  
}

Show all Users in a group:

static void Main(string[] args)
{
SPSite mySite = new SPSite("http://servername:port");
SPWeb myWeb = mySite.OpenWeb();
SPGroup myGroup = myWeb.Groups["Group Name"];
foreach (SPUser myUser in myGroup.Users)  
{  
Console.WriteLine(myUser.Name);  
}  
Console.WriteLine("Press any key to continue.....");  
Console.ReadLine();  
}

Show all Users in a group from UserCollection:

static void Main(string[] args)
        {
            SPSite mySite = new SPSite("http://servername:port");
            SPWeb myWeb = mySite.OpenWeb();
            SPUserCollection myUserCollection = myWeb.Groups["Group Name"].Users;
            foreach (SPUser myUser in myUserCollection)
            {
                Console.WriteLine(myUser.LoginName);
            }
            Console.WriteLine("Press any key to continue.....");
