在vb.net里面开发的一个函数
Option Strict Off
Imports System
Imports NXOpen
Imports NXOpen.UF
Imports NXOpen.Utilities

Module NXJournal
Sub Main

      Dim s As Session = Session.GetSession()
      Dim ufs As UFSession = UFSession.GetUFSession()

      Dim wp As Part = s.Parts.Work()

      Dim cyl_feat_tag As NXOpen.Tag
      Dim orig() As Double = {1, 1, 0}
      Dim dir() As Double = {1, 1, 1}

      ufs.Modl.CreateCylinder(FeatureSigns.Nullsign, Nothing, orig, "50","25", dir, cyl_feat_tag)

      Dim cyl_body_tag As Tag

      ufs.Modl.AskFeatBody(cyl_feat_tag, cyl_body_tag)
      Dim cyl_body As Body = CType(NXObjectManager.Get(cyl_body_tag), Body)

      cyl_body.Color = 3 ‘ //更改颜色
      cyl_body.RedisplayObject()
End Sub
End Module
我把它转换到c#里面遇到问题了
      Session s = Session.GetSession();
      UFSession ufs  = UFSession.GetUFSession();

      Part wp  = s.Parts.Work;

      NXOpen.Tag cyl_feat_tag;
      NXOpen.Tag cyl_feat_tag2;
      Double[] orig  = new double[3] {1, 1, 0};
      Double[] dir  = new double[3]{1, 1, 1};
try
{
ufs.Modl.CreateCylinder(FeatureSigns.Nullsign,cyl_feat_tag2,orig, "50","25", dir,out cyl_feat_tag);
}
catch(NXException pp)
{
MessageBox.Show(pp.Message);
}

      Tag cyl_body_tag;

      ufs.Modl.AskFeatBody( cyl_feat_tag,out cyl_body_tag);
      Body cyl_body = CType(NXObjectManager.Get(cyl_body_tag), Body);

      cyl_body.Color = 3;
      cyl_body.RedisplayObject();
因为我查看了CreateCylinder函数在c#里面的api，第二个和最后一个参数均为tag枚举，我定义了两个tag，但是程序出现异常，我用null代替第二个参数，提示不能转换null为tag，我查看api里面的NXOpen.tag为枚举，但是里面的内容为NULL，就一个东西，还有后面的CType函数不知道怎么用，而且ctype函数的第二个参数为一个类不知道怎么转换了，那位达人能给我将vb的程序转换到c#里面，小弟将不胜感激，跪谢了

UFSession和Session有什么区别？
