C# -如何从一个路径复制SQLite db并将其粘贴到另一个路径？

Question

使用下面的代码，如何在SQLiteConnetion对象中设置代码？

public SQLiteConnection dbConnection = new SQLiteConnection();

string fileName = "test.s3db";
        string sourcePath = @"E:\File\DMS\DAL\Model";
        string targetPath = @"C:\ProgramData\CompanyName\appName";
        string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
        string destFile = System.IO.Path.Combine(targetPath, fileName);
        if (!System.IO.Directory.Exists(targetPath))
        {
            System.IO.Directory.CreateDirectory(targetPath);

        }
        System.IO.File.Copy(sourceFile, destFile, true);
        if (System.IO.Directory.Exists(sourcePath))
        {
            string[] files = System.IO.Directory.GetFiles(sourcePath);
        }

如果路径不存在，我希望自动创建DB路径。

dbConnection = ??

我有一种复制数据库的方法：

public static void BackupDatabase(string sourceFile, string destFile)
{
    using (SQLiteConnection source = new SQLiteConnection(String.Format("Data Source = {0}", sourceFile)))
    using (SQLiteConnection destination = new SQLiteConnection(String.Format("Data Source = {0}", destFile)))
    {
        source.Open();
        destination.Open();
        source.BackupDatabase(destination, "main", "main", -1, null, -1);
    }
}
