在SQLite数据库中出现错误“文件已加密还是未加密数据库”？

Question

I am using SQLite Database in C# and trying to encrypt it but when I am setting the Password in Connection.SetPassword it is giving me above error.

connection.SetPassword("12345");
trans=connection.BeginTransaction();

I am getting the error on BeginTransaction() method. Is there any way to resolve it and set password successfully to SQLite Database.

Answer 1

You need to open the connection after setting the password.

Follow this example:

 connection = new SQLiteConnection(connString);
 //Set the password
 connection.SetPassword("12345");
 //Open the connection
 connection.Open();
 connection.Close();

If you want to connect to the same DB and remove the password then do as following:

 connection = new SQLiteConnection(connString);
 connection.SetPassword("12345");
 connection.Open();
 connection.ChangePassword("");
 connection.Close();
