用法
Dim instance As SPFarm
[GuidAttribute("674DA553-EA77-44a3-B9F8-3F70D786DE6A")]
[UpgradableAttribute]
[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel = true)]

IBackupRestore, IMigratable
备注
SPFarm是用于在配置数据存储区进行交互的可扩展的配置对象模型中的顶级节点。它包含所有服务器、 服务和解决方案安装在服务器场中的全局设置。使用Servers， Services或Solutions属性以检索这些集合。
若要访问在当前服务器场对象，您可以在SPFarm.Local上使用成员。例如，若要返回一个SPServiceCollection对象，代表在当前服务器场中的服务的集合，请使用SPFarm.Local.Services。此外，您可以使用SPPersistedObject类中派生的类的Farm属性，或者可以使用SPSolution类的Farm属性来获取当前对象，或者解决方案的服务器场。
示例
下面的示例注册一个自定义的作业定义在当前服务器场中每个 Web 应用程序上。
Dim farm As SPFarm = SPFarm.Local
Dim service As SPWebService = farm.Services.GetValue < SPWebService > ""
Dim webApp As SPWebApplication
For Each webApp In service.WebApplications
Dim job As SPJobDefinition
For Each job In webApp.JobDefinitions
If job.Name = "MyCustomJobDefinitionName" Then
j.Delete()
End If
Next job
Dim newJob As New MyCustomJobDefinition("MyCustomJobDefinitionName", webApp)
Dim schedule As SPSchedule = SPSchedule.FromString("every 5 minutes between 0 and 59")
newJob.Schedule = schedule
newJob.Update()
Next webApp
SPFarm farm = SPFarm.Local;
SPWebService service = farm.Services.GetValue<SPWebService>("");
foreach (SPWebApplication webApp in service.WebApplications)
{
foreach (SPJobDefinition job in webApp.JobDefinitions)
{
if (job.Name == "MyCustomJobDefinitionName")
{
j.Delete();
}
}
MyCustomJobDefinition newJob = new
MyCustomJobDefinition("MyCustomJobDefinitionName", webApp);
SPSchedule schedule = SPSchedule.FromString("every 5 minutes between 0 and 59");
newJob.Schedule = schedule;
newJob.Update();
}
