示例
下面演示的SPBackupRestoreObjectCollection类正在使用中的方法，将确保该组件名称由用户提交唯一标识单个组件进行备份或还原操作的组件的树的顶部。有关完整的示例和详细的讨论，请参阅How to: Programmatically Back Up Content。
private static SPBackupRestoreObject EnsureUniqueValidComponentName(SPBackupRestoreSettings settings, ref Guid operationGUID)
{
SPBackupRestoreObjectCollection list = SPBackupRestoreConsole.FindItems(operationGUID, settings.IndividualItem);
SPBackupRestoreObject component = null;
if (list.Count <= 0)
{
Console.WriteLine("There is no component with that name. Run again with a new name.");
Console.WriteLine("Press Enter to continue.");
Console.ReadLine();
}
else if (list.Count > 1) // The component name specified is ambiguous. Prompt user to be more specific.
{
Console.WriteLine("More than one component matches the name you entered.");
Console.WriteLine("Run again with one of the following:");
for (int i = 0; i < list.Count; i++)
{
Console.WriteLine("\t{0}", list[i].ToString());
}
Console.WriteLine("Press Enter to continue.");
Console.ReadLine();
}
else
{
component = list[0];
}
return component;
}// end EnsureUniqueValidComponentName
