How to use C # code to manage SharePoint Solutions

How to use C # code to manage SharePoint solutions This article describes how to use code to manage SharePoint solutions. We use the server-side object model extraction solution. There are two solutions in SharePoint: Sandbox solution and field solution. Sandbox solutions and field solutions are deployed in different ways and extracted using different object models. Note: spusersolution is used here to represent the sandbox solution; spfarmsolution represents the field solution. How to obtain the sandbox solution is deployed at the website set level. The following is a centralized solution for extracting all users from the website:

using (SPSite site = new SPSite("http://localhost")){    foreach (SPUserSolution solution in site.Solutions)    {        Console.WriteLine(solution.Name);        Console.WriteLine(solution.Status);    }}

The code for how to obtain a field solution to extract all the field solutions is as follows:

foreach (SPSolution solution in SPFarm.Local.Solutions){    Console.WriteLine(solution.Name);    Console.WriteLine(solution.SolutionId);    Console.WriteLine(solution.Status);}

Next, let's take a look at how to install the solution through the server-side object model. To install the sandbox solution, follow these steps: add to database and activate. The following code adds a solution to the database:

using (SPSite site = new SPSite("http://localhost")){    SPDocumentLibrary gallery              =(SPDocumentLibrary)site.GetCatalog(SPListTemplateType.SolutionCatalog);    SPFile file = gallery.RootFolder.Files.Add("SandboxedSolution.wsp",       File.ReadAllBytes("SandboxedSolution.wsp"));     SPUserSolution solution = site.Solutions.Add(file.Item.ID);}

Remove sandbox solution remove solution and disable function use the following code:

using (SPSite site = new SPSite("http://localhost")){    SPUserSolution solution = site.Solutions.Cast<SPUserSolution>().                                             Where(s => s.Name == "Your Solution").First();    site.Solutions.Remove(solution);}

Use the following code to install the on-site solution:

private static void InstallFarmSolution(){    SPSolution solution = SPFarm.Local.Solutions.Add("File Path here");    solution.Deploy(DateTime.Now, true, GetAllWebApplications(), true);}

We need to specify the solution path. The above Code allows the solution to be installed in all web applications. The main body of the getallwebapplication () method is as follows:

public static Collection<SPWebApplication> GetAllWebApplications(){    Collection<SPWebApplication> result = new Collection<SPWebApplication>();    SPServiceCollection services = SPFarm.Local.Services;    foreach (SPService s in services)    {        if (s is SPWebService)        {            SPWebService webService = (SPWebService)s;            foreach (SPWebApplication webApp in webService.WebApplications)            {                result.Add(webApp);            }        }    }    return result;}

Remove a farm solution remove a farm solution become a recovery solution. This is an appropriate method:

private void RetractFarmSolution(SPSolution solution){    solution.Retract(DateTime.Now);}

Create a timer job recovery solution. You can specify the start time. Only remove the solution from the specified web application. Refer to this method:

private void RetractFarmSolution(SPSolution solution, Collection<SPWebApplication> webApplications){    solution.Retract(DateTime.Now, webApplications);}

In summary, we learned how to use the server-side object model to extract sandbox solutions and field solutions.
