Параметры

• applicationDatabaseFileGroup
  The parent ApplicationDatabaseFileGroup object for the database file.

• name
  A String, between 1 and 128 characters in length, specifying the logical name of the data file.

  You cannot change the name. To alter an application database after creating the application, use the SQL Server tools, such as SQL Server Management Studio.

Замечания

In addition to providing values for the parameters, you also must set the FileName property.

The name parameter specifies the logical name of the database data file. The logical name is used to refer to the file when managing the data file.

Using Notification Services Management Objects (NMO), you cannot update any database properties after creating the application.

Пример

The following examples show how to define an application database file:

// Define and add a filegroup
ApplicationDatabaseFileGroup adb_fg = 
    new ApplicationDatabaseFileGroup(adb, "PRIMARY");
adb.ApplicationDatabaseFileGroups.Add(adb_fg);

// Define and add a database file
ApplicationDatabaseFile adb_file1 = 
    new ApplicationDatabaseFile(adb_fg, "MyApp_PrimaryFile1");
adb_file1.FileName = @"C:\NS\Full\MyApp_PrimaryFile1.mdf";
adb_file1.InitialSize = "10MB";
adb_file1.MaxSize = "50MB";
adb_file1.GrowthIncrement = "10%";
adb_fg.ApplicationDatabaseFiles.Add(adb_file1);

' Define and add a filegroup
Dim adb_fg As ApplicationDatabaseFileGroup = _
    New ApplicationDatabaseFileGroup(adb, "PRIMARY")
adb.ApplicationDatabaseFileGroups.Add(adb_fg)

' Define and add a database file
Dim adb_file1 As ApplicationDatabaseFile = _
    New ApplicationDatabaseFile(adb_fg, "MyApp_PrimaryFile1")
adb_file1.FileName = "C:\NS\Full\MyApp_PrimaryFile1.mdf"
adb_file1.InitialSize = "10MB"
adb_file1.MaxSize = "50MB"
adb_file1.GrowthIncrement = "10%"
adb_fg.ApplicationDatabaseFiles.Add(adb_file1)
