C#中实现在32位、64位系统下自动切换不同的SQLite dll文件

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;
      }
    }
  }
}
