连接总是超时,即使它在trycatch内也不会生成错误消息。我怀疑连接字符串有问题。这是我目前有:使用SqlDataReader连接到本地.mdb文件的正确方法?
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.
我也尝试了关系路径的连接字符串,如:
string connectionstring = "Database=wantedDB;AttachDBFilename=\"wantedDB.mdb\";Server=(local)";
的DB是不是受密码保护。我有MS Access安装,这是否影响这个莫名其妙?我错过了什么?
有什么问题是什么呢?任何错误消息? – ChrisWue 2012-03-07 05:34:59
