Install Features Programmatically in SharePoint
Generally, we use STSADM command line to install features by “STSADM –o installfeature –name FeatureName” or Install-SPFeature PowerShell Cmdlet. At times, we may have to execute stsadm programmatically to install a Feature. Say for e.g. from console applications or from another feature activation code. Here is how it can be achieved.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Administration;
using System.Diagnostics;
namespace InstallFeature
{
class Program
{
static void Main(string[] args)
{
string site;
if (args.Length == 0)
{
Console.WriteLine("Enter the Web Application URL:");
site = Console.ReadLine();
}
else
{
site = args[0];
}
SPSite tmpRoot = new SPSite(site);
//Get the particular Feature, if installed already
SPFarm farm = tmpRoot.WebApplication.Farm;
SPFeatureDefinitionCollection features = farm.FeatureDefinitions;
SPFeatureDefinition feature = features[new Guid("05BA4E54-C1E9-4244-8276-06451EBBB260")];
if (feature == null) //Feature is not installed!
{
// install the feature
Process oProcess = new Process();
ProcessStartInfo oProcInfo = new ProcessStartInfo();
// Get the STSADM command's path
string commonFilesPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.CommonProgramFiles);
oProcInfo.FileName = commonFilesPath + @"\Microsoft Shared\web server extensions\12\BIN\" + "stsadm.exe ";
oProcInfo.Arguments = " -o installfeature -name Crescent.Support.Link -force";
oProcInfo.WindowStyle = ProcessWindowStyle.Hidden;
oProcInfo.UseShellExecute = true;
oProcess.StartInfo = oProcInfo;
//execute the stsadm command.
oProcess.Start();
oProcess.WaitForExit();
}
}
}
}
