这是我的代码；

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();

Answer 1

似乎该URL已损坏（与OleDB连接无关）：

http://www.acoin.co.il/database1.mdb ：

404-找不到文件或目录。
您正在寻找的资源可能已被删除，名称已更改或暂时不可用。

但是，如果您可以使用HTTP URL作为数据库文件位置，我会感到惊讶
