将Access DB表加载到Datatable

我有一个.ACCDB格式的数据库和一些表。

我使用以下代码成功将其加载到OleDbDataReader中：

string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;data source=C:\\marcelo.accdb"; OleDbConnection conn = new OleDbConnection(connectionString); string sql = "SELECT * FROM Clientes"; OleDbCommand cmd = new OleDbCommand(sql, conn); conn.Open(); OleDbDataReader reader; reader = cmd.ExecuteReader(); 

我想将表“clientes”加载到数据表中。 我该怎么办？

 string connString = "Provider=Microsoft.ACE.OLEDB.12.0;data source=C:\\marcelo.accdb"; DataTable results = new DataTable(); using(OleDbConnection conn = new OleDbConnection(connString)) { OleDbCommand cmd = new OleDbCommand("SELECT * FROM Clientes", conn); conn.Open(); OleDbDataAdapter adapter = new OleDbDataAdapter(cmd); adapter.Fill(results); }
