這是我的代碼;

string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=http://www.acoin.co.il/database1.mdb;Persist Security Info=False"; 
OleDbConnection conn = new OleDbConnection(connectionString); 
conn.Open();

好像該URL被打破（無關OLEDB連接）：

http://www.acoin.co.il/database1.mdb：

404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.

不過，我會感到驚訝，如果你可以使用一個HTTP URL作爲數據庫文件位置
