//数据库名的后缀你可以直接指定，甚至没有后缀都可以

//方法一：创建一个空sqlite数据库，用IO的方式

FileStream fs = File.Create(“c:\\test.db“);

//方法二：用SQLiteConnection

SQLiteConnection.CreateFile(“c:\\test.db“);

SQLiteConnection.CreateFile（“c:\\test2.db“);

SQLiteConnection cnn = new SQLiteConnection(“Data Source=c:\\test2.db“);

SQLiteConnection cnn = new SQLiteConnection(“Data Source=D:\\test2.db“);

cnn.Open();

cnn.ChangePassword(“password“);

SQLiteConnection cnn = new SQLiteConnection(“Data Source=c:\\test.db“);

cnn.Open();

cnn.ChangePassword(“password“);

//方法一

SQLiteConnection cnn = new SQLiteConnection(“Data Source=c:\\test2.db“);

cnn.SetPassword(“password“);

cnn.Open();

//方法二

SQLiteConnectionStringBuilder builder = new SQLiteConnectionStringBuilder();

builder.DataSource = @”c:\test.db“;

builder.Password = @”password“;

SQLiteConnection cnn = new SQLiteConnection(builder.ConnectionString);

cnn .Open();
