Before you continue reading this post, I hope you have read the basic task to start using lambda expression in SOM here.
A. Find existing job definition, named “Change Log”
SPWebApplication spWebApplication = SPContext.Current.Site.WebApplication;
var jobs = spWebApplication.JobDefinitions.Where(x => x.Title == "Change Log");
foreach(SPJobDefinition job in jobs)
Console.WriteLine(job.Id);
B. Find existing custom job definition MyCustomJobDefinition, named “My Custom Job”
SPWebApplication spWebApplication = SPContext.Current.Site.WebApplication;
var jobs = spWebApplication.JobDefinitions.OfType<MyCustomJobDefinition>().Where(x => x.Title == "My Custom Job");
foreach(SPJobDefinition job in jobs)
Console.WriteLine(job.Id);
C. Find site collection from “STS” template
SPWebApplication webApplication = SPContext.Current.Site.WebApplication;
var allSPSite = webApplication.Sites.OfType<SPSite>().Where(s => s.RootWeb.WebTemplate.Equals("STS", StringComparison.InvariantCultureIgnoreCase));
foreach(SPSite spSite in allSPSite)
{
// operation in the SPSite
}
D. Find All RootWeb (of Site collection)
SPWebApplication spWebApplication = SPContext.Current.Site.webApplication;
var rootWebs= spWebApplication.Sites.OfType<SPSite>().Select ( s => s.RootWeb );
foreach (SPWeb spWeb in rootWebs)
{
// Do your task here
}
E. Find if Site Collection with RootWeb contains list named “Sample List”
SPWebApplication spWebApplication = SPContext.Current.Site.webApplication;
var sites = spWebApplication.Sites.OfType<SPSite>().Where(
s => s.RootWeb.Lists.OfType<SPList>().Where(
l => l.Title.Equals("Sample List",StringComparison.InvariantCultureIgnoreCase)).Count() > 0);
foreach (SPSite spSite in sites)
{
// Do your task here
}
F. Find if RootWeb which contains list named “Sample List”
SPWebApplication spWebApplication = SPContext.Current.Site.webApplication;
var rootWebs = spWebApplication.Sites.OfType<SPSite>().Select(s => s.RootWeb).Where(
r => r.Lists.OfType<SPList>().Where(
l => l.Title.Equals("Sample List",StringComparison.InvariantCultureIgnoreCase)).Count() > 0);
foreach (SPWeb spWeb in rootWebs)
{
// Do your task here
}
