在Visual Studio 2010 C＃中找不到数据库

Question

I've been creating an application using Visual Studio 2010 C# and Microsoft Access 2007. I am new to this and I am experiencing some errors. I've tried using MySQL as a database before but when I changed it to MS Access 2007, there are errors occured stating that the database format is not recognized.

Here's the print screen:

The file type of the database I created is .accdb . Please help. Thanks

Answer 1

您用于连接accdb数据库的驱动程序已过时，请安装Access 2010驱动程序 ，然后以这种方式更改您的连接字符串：

string MyConString = Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\pathofyourDatabase.accdb

Answer 2

Either the database is encrypted or you don't have the proper Access engine for the architecture (x86/x64). Visual Studio is also 32-bit and probably can't connect to x64 database. See this post .
