System.ArgumentException: 不支持关键字: “provider”
===================================================
不是你提供的protected static string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source= " +dppath+ "; ";这一行
它找到的错误是小写的(大小写不关键,但你的代码那里还有小写的provider)
[解决办法]
改用 OLEDB
[解决办法]
Data Source= 'fdc.mdb ';Jet OLEDB:database password=123; Provider= 'Microsoft.Jet.OLEDB.4.0 ';User ID=Admin
连接字符串
[解决办法]
呀，LZ 你竟然要 SqlConnection 去连 Access ？？？？
请使用 OleDbConnection 以及相关类
public static DataTable GetDataTable(string strSQL)
{
SqlConnection Conn = new SqlConnection(strConn);
//DataTable datatable=new DataTable();
try
{
Conn.Open();
SqlDataAdapter sda = new SqlDataAdapter(strSQL,Conn);
DataTable dt = new DataTable( "dt ");
sda.Fill(dt);
return dt;
}
catch(System.Data.SqlClient.SqlException e)
{
throw new Exception(e.Message);
}
finally
{
Conn.Close();
}
}
》》》
public static DataTable GetDataTable(string strSQL)
{
OleDbConnection Conn = new OleDbConnection(strConn);
//DataTable datatable=new DataTable();
try
{
Conn.Open();
OleDbDataAdapter sda = new OleDbDataAdapter(strSQL,Conn);
DataTable dt = new DataTable( "dt ");
sda.Fill(dt);
return dt;
}
catch(System.Data.OleDbClient.OleDbException e)
{
throw new Exception(e.Message);
}
finally
{
Conn.Close();
}
}
Good Luck！

呵呵，才发现，楼上说的对
