Microsoft.SqlServer.Management.Smo.Agent Namespace
The Microsoft.SqlServer.Management.Smo.Agent namespace contains classes that represent the Microsoft SQL Server Agent.
已更新的文本：2006 年 7 月 17 日
The Microsoft.SqlServer.Management.Smo.Agent namespace represents the SQL Server Agent. After a connection to an instance of SQL Server has been established by using the Server object variable, you can use the objects in the Microsoft.SqlServer.Management.Smo.Agent namespace to manage the SQL Server Agent.
The Microsoft.SqlServer.Management.Smo.Agent namespace resides in the Microsoft.SqlServer.Sm.dll assembly file. Also, some of the enumeration classes are in the Microsoft.SqlServer.SqlEnum.dll and Microsoft.SqlServer.SmoEnum.dll assembly files. You will have to import all three files to access the classes in the Microsoft.SqlServer.Management.Smo.Agent namespace.
By using the Microsoft.SqlServer.Management.Smo.Agent namespace, you can do the following:
View and modify SQL Server Agent settings.
Set up and manage operators.
Set up and manage alerts based on system messages or performance conditions.
Set up and manage jobs with multiple steps and schedules.
Manage proxy accounts for the subsystems on which jobs run.
Manage jobs that run on multiple servers.

Enumerations
| Enumeration | Description |
|---|---|

| CategoryType | The CategoryType enumeration is a list of constant values that specify the type of category, such as whether the category refers to local jobs or multiserver administration. |
| CompletionAction | The CompletionAction enumeration is a list of constant values that specify the circumstances when a job completes after which another action is executed. |
| CompletionResult | The CompletionResult enumeration is a list of constant values that specify the status on completion of a job or job step. |
| FindOperand | The FindOperand enumeration represents a list of operands that are used to evaluate the DateJobCreated and DateJobLastModified properties to specify a range of dates in a job filter. |
| FrequencyRelativeIntervals | The FrequencyRelativeIntervals enumeration contains values that are used to specify the ordinal position of a recurring occurrence within a specified period. |
| FrequencySubDayTypes | The FrequencySubDayTypes enumeration contains values that are used to specify the way in which scheduling is managed within the period of a day. |
| FrequencyTypes | The FrequencyTypes enumeration contains values that are used to specify how often a schedule is executed. |
