How to create a database after MDF files and LDF files __ Database

Today downloaded a C # source code, used to the database.

The source project has the file to create the database, is the database master file and log file, the format is MDF (database Master file) and a LDF (log file).

The steps to create a database with these two files are as follows:

1. Create a database using the file name of the MDF file (you can create it with the SQL Server Management Studio tool)

2. Shut down the database program and stop the database service

3. Find the directory where the database file you just created is located, typically under C:/Program Files/microsoft SQL Server/mssql.1/mssql/data (I'm using SQL Server Express Edition)

3. Overwrite the database file you just created with the two files you downloaded.

4. Restart the database service and reopen the database to see the data in the database.
