我猜你需要這樣的東西。

SqlConnection connection = new SqlConnection("[your connection string goes here]"); 
    connection.Open(); 

    SqlCommand cmd = new SqlCommand("INSERT INTO tblAdd_Subject(Subject1, Subject2, Subject3, Subject4, Subject5) values(@Subject1, @Subject2, @Subject3, @Subject4, @Subject5)", connection); 

    cmd.Parameters.Clear(); 
    cmd.Parameters.AddWithValue("@Subject1", chk1.Checked ? "some value for subject 1" : string.Empty); 
    cmd.Parameters.AddWithValue("@Subject2", chk2.Checked ? "some value for subject 2" : string.Empty); 
    cmd.Parameters.AddWithValue("@Subject3", chk3.Checked ? "some value for subject 3" : string.Empty); 
    cmd.Parameters.AddWithValue("@Subject4", chk4.Checked ? "some value for subject 4" : string.Empty); 
    cmd.Parameters.AddWithValue("@Subject5", chk5.Checked ? "some value for subject 5" : string.Empty); 

    cmd.ExecuteNonQuery();
