通过c＃regex帮助查找所有“rect NAME = null”。（在全局和全球之间）

    //Text example:
...
         globals
            ...
        boolexpr cj_true_bool_4896bnao87
        string udg_globals = "endglobals"
        trigger gg_trg___________________________u=null
        rect gg_rct_MyReg1=null
        rect     ra2462346  =            null
            ...
          endglobals
...

我的代码（，工作）：

private void openFileDialog1_FileOk（object sender，CancelEventArgs E） { string startglobs = @“^ \ s * globals \ s * $”; string endglobs = @“^ \ s * endglobals \ s * $”; string currrect = @“^ \ s * rect \ s +（。）\ s = \ s * null \ s *”;

                using (StreamReader file = new StreamReader(openFileDialog1.FileName))
                {
                    string currline;
                    bool globalstate = false;
                    while ((currline = file.ReadLine()) != null)
                    {
                        /* find globals */
                        Regex startr = new Regex(startglobs);
                        Match startm = startr.Match(currline);
                        if (startm.Success)
                            globalstate = true;


                        /* find endglobls */
                        Regex endr = new Regex(endglobs);
                        Match endm = endr.Match(currline);
                        if (endm.Success)
                            globalstate = false;

                        /* if opened globals find global rect */
                        if (globalstate)
                        {
                            Regex foundrectr = new Regex(currrect);
                            Match foundrectm = foundrectr.Match(currline);
                            if (foundrectm.Success)
                            {
                                MessageBox.Show(foundrectm.Groups[1].ToString());
                            }
                        }
                    }

                }

            }

我会给你一个提示......

你想要的正则表达式是

rect (.*)\s?=\s?null

您现在需要学习如何使用正则表达式运行它，并且您可能会发现MatchCollections和Groups很有趣。

现在已经足够让你在10分钟内解决问题，但你必须自己做一些阅读...
