Creating a series of SQLite tables from a list of classes

Question

I have generated a list of public classes that need to be added into an SQLite database.

I get the class names like this

private List<Type> types = new List<Type>();
...
var pathName = Directory.GetFiles(string.IsNullOrEmpty(dirPath) ? "SQLClasses" : dirPath);
foreach (var path in pathName)
    types.AddRange(Assembly.LoadFrom(path).GetTypes());

types now contains my classes that need to be turned into SQLite tables.

Normally, I would create my tables like this

using (SQLiteConnection sqlCon = new SQLiteConnection(DBPath))
{
     sqlCon.CreateTable<TableName>();

As I already have my list of classes held in types, I'm trying to insert these tables into the database using a simple foreach

Currently I have this

foreach(var t in types)
{
    var T = Activator.CreateInstance(t);
    sqlCon.CreateTable<T>();
}

neither this nor the simpler

sqlCon.CreateTable<typeof(t)>();

or

sqlCon.CreateTable<t>();

work (all three give T [or t] doesn't exist in the current context)

Can I use this simple foreach method to insert the table names or do I have to do something more complex?

Answer 1

The answer is that CreateTable has two overloaded methods

sqlCon.CreateTable<T>();

and

sqlCon.CreateTable(t);

the second allowing for a type to be used rather than a generic class of T to be used. I was unaware of this second method until I noticed some obscure reference on a website than mentioned a second method but failed to say what it was. Digging around found this.

My apologies for not providing a fuller answer earlier
