any suggestions?

Answer 1

The value that was provided for the
connection string may be wrong, or it
may contain an invalid syntax.
My suggestion is to fix the configuration string.

Answer 2

This MSDN article contains all allowed keyword values within the ConnectionString for SqlConnection object. "Provider" is not in the list.
You have two options:
remove "provider" keyword;
use an OleDbConnection instead of SqlConnection.

Answer 3

Also When your connection string parameter "User ID" use the space, if it is written as "UserID" then also it gives error

Answer 4

Remove "Provider=MSDORA" from your connection string. And then this should work.

Answer 5

Watch for keywords in the connectionstring which NEED spaces. Like User ID is correct but UserID will fail.
