C# SQLite 在32位和64位下自动切换不同的dllusing System; using System.Collections.Generic; using System.Windows.Forms; using System.Management; using System.IO; namespace SqliteAuto { static class Program { /// <summary> /// 应用程序的主入口点。 /// </summary> [STAThread] static void Main() {
st_jar说的有理
但是实现起来,有一些现实的困难,在我的项目中没办法,只能改x86了
