推荐答案
试试这个代码,
public void ConnectToAccess()
{
System.Data.OleDb.OleDbConnection conn = new
System.Data.OleDb.OleDbConnection();
// TODO: Modify the connection string and include any
// additional required properties for your database.
conn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;" +
@"Data source= C:Documents and Settingsusername" +
@"My DocumentsAccessFile.mdb";
try
{
conn.Open();
// Insert code to process data.
}
catch (Exception ex)
{
MessageBox.Show("Failed to connect to data source");
}
finally
{
conn.Close();
}
}
