Do you have a backup of your wallet.dat?
Usually files don't get corrupted when moving them into the recycle bin, but in windows you can't be sure.
You need to place the wallet.dat into the data directory of core.
To open the directory you can do the following (assuming you are on windows):
- Press WinKey + R (Run command)
- Type: %APPDATA%\Bitcoin
- Press Enter
The right folder should open automatically.
Backup your wallet.dat which is in the datadir (rename it) and move your recovered wallet.dat into the folder.
The standard path of the datadir is: C:\Users\YourUserName\Appdata\Roaming\Bitcoin
