我有一个应用程序查询Access数据库并显示数据。我想连接（con）2分钟后超时。

I have an app that queries an Access database and shows the data. I want the connection(con) to timeout after 2 minutes. Does anyone have any suggestions on how i can code this?

这是我在开始时所拥有的

this is what i have in the beginning

OleDbConnection con;
OleDbDataReader dr;
OleDbCommand cmd;

con.Open();
cmd = new OleDbCommand(str, con);
dr = cmd.ExecuteReader();

推荐答案

不要共享连接，在需要时创建连接，并使用块

Don't share the connection, create the connection when you need and wrap it by using block,

如果您需要设置超时，可以使用属性（例如.....; （OleDbConnection con = new OleDbConnection（connectionString））$ b $连接超时= 30

if you need to set the timeout, you can set by using ConnectionTimeout property in connection string (e.g. ".....;Connect Timeout=30"

using (OleDbConnection con = new OleDbConnection(connectionString))
using (OleDbCommand cmd = new OleDbCommand(str, con))
{
   con.Open();
   using (OleDbDataReader dr = cmd.ExecuteReader())
   {

   }
}
