About C # Joining a database is a workaround for the ' not registered on local computer ' error

There's a weird problem with using C # to connect to an Access database today.

The Microsoft.ACE.OLEDB is not registered on the local computer. 12.0"Provider

Some of our code is as follows:

            string " Provider=microsoft.ace.oledb.12.0;data source= " ;             string str = System.Environment.CurrentDirectory;             " \\Database.accdb " ;    

So the question is in the first sentence, actually just see this thing, my roommate and I look like this

Because this code is the last semester of our C # final work of the code, is the test of the defense can run code!!! (10,000 head Grass Mud horse ~)

However, we have no way, can only first go to Baidu, hehe, did not solve.

Then I search for stack overflow and find a solution that most people agree with, but

Step Big Big trouble, I do a little trivial, this input is not proportional to output.

Finally, this problem is resolved by a degenerate format (. mdb) that was saved as 2000 after opening the file with access2016

Then change the top code to

string " Provider=Microsoft.Jet.OLEDB.4.0;Data source= ";

Then you can change the file name. ~ ~ ~
