Use SQLite in C #

(1) download SQLite (sqlite-netFx40-setup-bundle-x64-2010-1.0.83.0) from the following URL ):

Http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki

Using: using system. Data. SQLite;

Add code: sqliteconnection. createfile (datasource); the following error is reported during running (the first time you use C #, please help analyze the cause of the error ):

Csdn user reply may be due to the following reasons:
It may be that the Framework configuration is incorrect. SQLite is. Net 4.0, and your console is. Net 4.0 client profile;
. Net 4.0 is greater than. Net 4.0 client profile to view project properties. try to change it.
. Net 4.0 client profile takes less space than. Net 4.0, but supports less types than. Net 4.0.
The dynamic library of SQLite is not supported by. Net 4.0 client profile.
Not verified.

(2) downloaded: SQLite-1.0.66.0-setup.exe, installed in vs2010 menu "Add new data source" "New Connection..." finally found the SQLite option.
Then, modify the target framework of the project from 4.0 to 3.5. Otherwise, an error is reported during compilation.
Finally, add reference in the project and select system. Data. SQLite. dll and system. Data. SQLite. dll in the \ SQLite. Net \ bin directory (optional)

(3) create a database
