Directory.Move 方法
将文件或目录及其内容移到新位置。
**命名空间:**System.IO
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
Public Shared Sub Move ( _
sourceDirName As String, _
destDirName As String _
)
用法
Dim sourceDirName As String
Dim destDirName As String
Directory.Move(sourceDirName, destDirName)
public static void Move (
string sourceDirName,
string destDirName
)
public:
static void Move (
String^ sourceDirName,
String^ destDirName
)
public static void Move (
String sourceDirName,
String destDirName
)
public static function Move (
sourceDirName : String,
destDirName : String
)
参数
- sourceDirName
要移动的文件或目录的路径。
- destDirName
指向 sourceDirName 的新位置的路径。
异常
| 异常类型 | 条件 |
|---|---|
试图将一个目录移到不同的卷。 - 或 - destDirName 已存在。 - 或 - sourceDirName 和 destDirName 参数引用相同的文件或目录。 |
|
调用方没有所要求的权限。 |
|
sourceDirName 或 destDirName 是一个零长度字符串，仅包含空白或者包含一个或多个由 InvalidPathChars 定义的无效字符。 |
|
sourceDirName 或 destDirName 为 空引用（在 Visual Basic 中为 Nothing）。 |
|
指定的路径、文件名或者两者都超出了系统定义的最大长度。例如，在基于 Windows 的平台上，路径必须小于 248 个字符，文件名必须小于 260 个字符。 |
|
由 sourceDirName 指定的路径无效（例如，它位于未映射的驱动器上）。 |
备注
举例来讲，如果您尝试将 c:\mydir 移到 c:\public，并且 c:\public 已存在，则此方法引发 IOException。您必须将“c:\\public\\mydir”指定为 destDirName 参数（假设“c:\\public”下不存在“mydir”），或者指定一个新的目录名，例如“c:\\newdir”。
允许 sourceDirName 和 destDirName 参数指定相对或绝对路径信息。相对路径信息被解释为相对于当前工作目录。若要获取当前工作目录，请参见 GetCurrentDirectory。
