SQLite no such table in C#
===

**I write this C# Code for insert one text data to my database table:**

    SQLiteConnection con = new SQLiteConnection("Data Source=tDB1.sqlite;Version=3;");
    string q1 = "INSERT INTO tMembers(mName) VALUES(?)";
    
    SQLiteCommand cmd1 = new SQLiteCommand(q1, con);
    cmd1.Parameters.AddWithValue("@mName", txtName.Text);
    
    con.Open(); 
    cmd1.ExecuteNonQuery(); 
    con.Close();

I copy my tDB1.sqlite  to my program folder and Create tMembers table in sqlite.

when i run my program,  program debugger show ""cmd1.ExecuteNonQuery();""  line and display to me:  SQLite error no such table

can any help me?
thank you.
