此方法适用于磁盘卷，如果源和目标相同，则不会引发异常。
请注意，如果尝试通过将同名文件移动到该目录中来替换文件，
IOException
则会引发 。 避免此问题的方法：
在 .NET Core 3.0 及更高版本中，可以调用
Move(String, String, Boolean)
将 参数
overwrite
true
设置为 ，这将替换文件（如果存在）。
在所有 .NET 版本中，可以调用
Copy(String, String, Boolean)
以使用 overwrite 进行复制，然后调用
Delete
以删除多余的源文件。 如果要复制的文件较小，并且你正在寻找“原子”文件操作，则建议使用此策略。
Delete
如果文件优先，并且系统或程序崩溃，则目标文件将不再存在。
在所有 .NET 版本中，可以在调用
Move
之前调用
Delete(String)
，这只会删除文件（如果存在）。
sourceFileName
和
destFileName
参数可以包含相对或绝对路径信息。 相对路径信息解释为相对于当前工作目录。 若要获取当前工作目录，请参阅
GetCurrentDirectory
。
跨磁盘卷移动文件等效于复制文件并从源中删除文件（如果复制成功）。
如果尝试跨磁盘卷移动文件，并且该文件正在使用中，则会将该文件复制到目标，但不会从源中删除该文件。
