asp.net中如何创建与数据库的连接类?
以下是用VB编写的.????可是不行...../????/
关键就是在server.mappath("demo.mdb")这个位置不行!!!
Public Function CreateConnDB()
Dim ConnAll As New OleDbConnection
ConnAll.ConnectionString = "Provider=Microsoft.Jet.OleDb.4.0;Data Source=" + server.mappath("demo.mdb")
ConnAll.Open()
CreateConnDB = ConnAll
End Function

是不是少个“;”

public bool conn()
{
SqlConnection conn = new SqlConnection("server=机器名;pwd=sa;uid=sa;database=数据库名");

try
{
conn.Open();
return true;
}
catch(Exception e)
{
return false;
}
finally
{
conn.Close();
}
}
