Well there are many ways you could achieve this and this is just one of them. It simply creates a new instance of the SPExecuteAdministrationServiceJobs class and calls its Run method. This will start and wait for all currently registered and/or running timer jobs to finish. The code is below:
string stsadmPath = SPUtility.GetGenericSetupPath(“BIN”);
Assembly stsadmAsm = Assembly.LoadFile(Path.GetFullPath(stsadmPath + “\\STSADM.EXE”));
Type admSvcJobType = stsadmAsm.GetType(“Microsoft.SharePoint.StsAdmin.SPExecuteAdministrationServiceJobs”);
ConstructorInfo ci = admSvcJobType.GetConstructor(new Type[] { typeof(SPGlobalAdmin) });
using (SPGlobalAdmin admin = new SPGlobalAdmin())
{
object svcjobs = ci.Invoke(new object[] { admin });
MethodInfo runMi = admSvcJobType.GetMethod(“Run”, BindingFlags.Instance | BindingFlags.Public);
runMi.Invoke(svcjobs, new object[] { new StringDictionary() });
}
One place this could be handy is when you provision a web application on multiple front ends using SPWebApplication.ProvisionGlobaly(). This method creates a timer job and returns immediately. However if you need the web application to be created before you continue you need to wait for the timer job(s) to finish. One way to do this programmatically is using the code above.
