How to specify a relative SQLite database path in C#?

Question

My database is located outside the application folder Example:

Database: SampleApplication\Database\Database.sqlite

Application: SampleApplication\Application\program.cs

My code is as below.

string relativePath = @"SampleApplication\Database\Database.sqlite";
string currentPath;
string absolutePath;
string connectionString;
currentPath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
absolutePath = Path.Combine(currentPath, relativePath);
connectionString = string.Format("Data Source={0};Version=3;Pooling=True;Max Pool Size=100;", absolutePath);
m_dbConnection = new SQLiteConnection(connectionString);
m_dbConnection.Open();

Solution

Alright, I figured it out guys.

string relativePath = @"Database\Database.sqlite";
var parentdir = Path.GetDirectoryName(Application.StartupPath);
string myString = parentdir.Remove(parentdir.Length -34, 34);
string absolutePath = Path.Combine(myString, relativePath);
string connectionString = string.Format("Data Source={0};Version=3;Pooling=True;Max Pool Size=100;", absolutePath);
m_dbConnection = new SQLiteConnection(connectionString);
m_dbConnection.Open();

I removed the characters from the parentdir till SampleApplication\ and added it with the relativePath. That makes an absolutePath to the database. The number 34 in the third line signifies how many characters to be remove from the end of parentdir.
