直接上代码：

using 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() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); string dll32 = System.Windows.Forms.Application.StartupPath + "\\lib\\SQLite32.DLL"; string dll64 = System.Windows.Forms.Application.StartupPath + "\\lib\\SQLite64.DLL"; string dllpath = System.Windows.Forms.Application.StartupPath + "\\System.Data.SQLite.dll"; if (Detect32or64() == "32") { // do 32bit things. try { using (FileStream fs = File.Create(dllpath)) { } File.Copy(dll32, dllpath, true); } catch { Console.WriteLine("ERR"); } } else if (Detect32or64() == "64") { //do 64bit things try { using (FileStream fs = File.Create(dllpath)) { } File.Copy(dll64, dllpath, true); } catch { Console.WriteLine("ERR"); } } Application.Run(new Form1()); } private static string Detect32or64() { try { string addressWidth = String.Empty; ConnectionOptions mConnOption = new ConnectionOptions(); ManagementScope mMs = new ManagementScope("\\\\localhost", mConnOption); ObjectQuery mQuery = new ObjectQuery("select AddressWidth from Win32_Processor"); ManagementObjectSearcher mSearcher = new ManagementObjectSearcher(mMs, mQuery); ManagementObjectCollection mObjectCollection = mSearcher.Get(); foreach (ManagementObject mObject in mObjectCollection) { addressWidth = mObject["AddressWidth"].ToString(); } return addressWidth; } catch (Exception ex) { Console.WriteLine(ex.ToString()); return String.Empty; } } }}
