即使连接在trycatch中,连接也会在不生成错误消息的情况下超时。我怀疑连接字符串有问题。这就是我目前所拥有的:
string path = @"C:\PATH\TO\wantedDB.mdb";
if (!File.Exists(path))
throw new FileNotFoundException("File not found.");
else
Console.WriteLine("File found."); // File is found, so nothing wrong with that.
string connectionstring = "Database=wantedDB;AttachDBFilename=" +
path + ";Server=(local)";
using (SqlConnection conn = new SqlConnection(connectionstring))
{
Console.WriteLine("Opening connection...");
conn.Open();
Console.WriteLine("Connection opened."); // Program never gets here.
我还尝试了连接字符串中的关系路径,如:
string connectionstring = "Database=wantedDB;AttachDBFilename=\"wantedDB.mdb\";Server=(local)";
db不受密码保护。我安装了MS Access,这会以某种方式影响这个吗?我错过了什么?

要连接到mdb文件,您应该使用OLEDB连接器:
var con = new OleDbConnection("Provider=Microsoft.JET.OLEDB.4.0;" + "data source=C:\\wantedDB.mdb;");
