主题：这个,net连接SQLITE的方法在FT里如何使用？

先下载ADO.NET2.0 Provider for SQLite。下载binaries zip版就可以了。下载完后解压缩，可以在bin目录下找到System.Data.SQLite.DLL。在vs2008中用Add Reference功能把System.Data.SQLite.DLL加到工程里就可以了。运行下面代码试试：
string datasource = "e:/tmp/test.db";
System.Data.SQLite.SQLiteConnection.CreateFile(datasource);
//连接数据库
System.Data.SQLite.SQLiteConnection conn = new System.Data.SQLite.SQLiteConnection();
System.Data.SQLite.SQLiteConnectionStringBuilder connstr = new System.Data.SQLite.SQLiteConnectionStringBuilder();
connstr.DataSource = datasource;
connstr.Password = "admin";//设置密码，SQLite ADO.NET实现了数据库密码保护
conn.ConnectionString = connstr.ToString();
conn.Open();
//创建表
System.Data.SQLite.SQLiteCommand cmd = new System.Data.SQLite.SQLiteCommand();
string sql = "CREATE TABLE test(username varchar(20),password varchar(20))";
cmd.CommandText = sql;
cmd.Connection = conn;
cmd.ExecuteNonQuery();
//插入数据
sql = "INSERT INTO test VALUES('a','b')";
cmd.CommandText = sql;
cmd.ExecuteNonQuery();
//取出数据
sql = "SELECT * FROM test";
cmd.CommandText = sql;
System.Data.SQLite.SQLiteDataReader reader = cmd.ExecuteReader();
StringBuilder sb = new StringBuilder();
while (reader.Read())
{
sb.Append("username:").Append(reader.GetString(0)).Append("\n")
.Append("password:").Append(reader.GetString(1));
}
MessageBox.Show(sb.ToString());
