Loading Access DB Table to Datatable
提问by Marcelo
I have a database in .ACCDB format with some tables.
我有一个带有一些表的 .ACCDB 格式的数据库。
I'm successfully loading it into an OleDbDataReader with the following code:
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();
I'd like to load the table "clientes" to a datatable instead. How should I do it ?
我想将表“clientes”加载到数据表中。我该怎么做？

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);
}
