这个接口，只会拷贝文件内容，不会修改文件名，例如数据库缓存，可以使用它，把备份数据库，替换正常的数据库文件，逻辑参考：
|
||
|
|
|
||
|
|
``` cs
|
||
|
|
/// <summary>
|
||
|
|
/// 从备份数据库中，恢复数据库
|
||
|
|
/// </summary>
|
||
|
|
/// <param name="backupPath"></param>
|
||
|
|
/// <param name="dbPath"></param>
|
||
|
|
/// <returns></returns>
|
||
|
|
private bool BackupDB(string backupPath,string dbPath)
|
||
|
|
{
|
||
|
|
if (File.Exists(backupPath))
|
||
|
|
{
|
||
|
|
File.Copy(backupPath,dbPath,true);
|
||
|
|
Debug.Log("已从备份恢复数据库");
|
||
|
|
return true;
|
||
|
|
}
|
||
|
|
else
|
||
|
|
{
|
||
|
|
File.Delete(dbPath);
|
||
|
|
Debug.LogError("无备份可用，已删除 损坏数据库");
|
||
|
|
return false;
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
