Adding a ListViewWebPart to Page

[UPDATE 01.Feb.2012: wp.ViewGuid = string.Empty gilt nur für 2007]
Hier eine Erklärung für 2010

[ENDUPDATE]

[UPDATE: Set View to "Summary View"]

using Microsoft.SharePoint;
using Microsoft.SharePoint.WebPartPages;

// Get a reference to a web and a list
SPSite site = new SPSite("http://localhost:8000");
SPWeb web = site.OpenWeb();
SPList list = web.Lists["Contacts"];

// Instantiate the web part
ListViewWebPart wp = new ListViewWebPart();
wp.ZoneID = "Left";
wp.ListName = list.ID.ToString("B").ToUpper();

// wp.ViewGuid = list.DefaultView.ID.ToString("B").ToUpper();
// Set the ViewGuid to string.Empty to get the "Summery View"
// including the "Add New Item"-Button



// Thanks to sadomovale

wp.ViewGuid = string.Empty;

// Get the web part collection
SPWebPartManager mgr = new SPWebPartManager("default.aspx", Storage.Shared);

// Add the web part
coll.Add(wp);
