How to restore, make changes and create a backup database in C#

Restore

To restore a database in C#, you can use the SqlConnection and SqlCommand classes to execute a RESTORE SQL query. Here is an example code snippet:

main.cs
using System.Data.SqlClient;

// Set up connection string
string connectionString = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;"

// Execute restore query
string restoreQuery = "RESTORE DATABASE [YourDatabaseName] FROM DISK = 'C:\\YourBackupFile.bak' WITH REPLACE";
using (SqlConnection connection = new SqlConnection(connectionString))
{
    using (SqlCommand command = new SqlCommand(restoreQuery, connection))
    {
        connection.Open();
        command.ExecuteNonQuery();
        connection.Close();
    }
}

Make Changes

To make changes to a database in C#, you can use the SqlConnection and SqlCommand classes to execute SQL queries. Here is an example code snippet that updates a table:

main.cs
using System.Data.SqlClient;

// Set up connection string
string connectionString = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;"

// Execute update query
string updateQuery = "UPDATE YourTable SET Column1 = 'NewValue' WHERE Column2 = 'SomeCondition'";
using (SqlConnection connection = new SqlConnection(connectionString))
{
    using (SqlCommand command = new SqlCommand(updateQuery, connection))
    {
        connection.Open();
        command.ExecuteNonQuery();
        connection.Close();
    }
}

Backup

To create a backup of a database in C#, you can use the SqlConnection and SqlCommand classes to execute a BACKUP SQL query. Here is an example code snippet:

main.cs
using System.Data.SqlClient;

// Set up connection string
string connectionString = "Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;"

// Execute backup query
string backupQuery = "BACKUP DATABASE [YourDatabaseName] TO DISK = 'C:\\YourBackupFile.bak'";
using (SqlConnection connection = new SqlConnection(connectionString))
{
    using (SqlCommand command = new SqlCommand(backupQuery, connection))
    {
        connection.Open();
        command.ExecuteNonQuery();
        connection.Close();
    }
}

Note that in all of these examples, you will need to substitute YourDatabaseName with the actual name of your database, and C:\\YourBackupFile.bak with the file path and name of your backup file.
