定义

命名空间:

Microsoft.SqlServer.Dts.Tasks.FileSystemTask

程序集:

Microsoft.SqlServer.FileSystemTask.dll

确定要对文件或目录设置的属性。

此枚举具有 FlagsAttribute 特性，允许其成员值的按位组合。

此枚举支持其成员值的按位组合。

属性

FlagsAttribute

字段

Archive	1	文件或目录可供存档。
Hidden	2	文件或目录不可见。
Normal	0	文件或目录没有其他属性集。 仅在单独使用时才有效。
ReadOnly	4	文件或目录为只读。
System	8	文件或目录是操作系统文件。

示例

下面的代码示例在 FileSystemTask 包中创建一个作为一个 Executable 。 该 FileSystemTask 测试文件夹将包含两个子文件夹和一个.txt文件的测试文件夹复制到另一个文件夹。 源文件夹的文件夹和子文件夹的属性设置为只读，因为 Attributes 该属性在代码示例中设置为 ReadOnly 。
