不打开revit判断rvt版本

上次是用程序直接读取rvt，来判断

还有一种方法，使用解压软件解压到文件夹，目录结构为

 其中rvt的版本在BasicFileInfo中

使用Java来判断

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class RevitVersion {

    public static void main(String[] args) {

        String fileName = "E:\\test\\BasicFileInfo";
        String version = rvtVersion(fileName);
        System.out.println(version);
    }

    public static String rvtVersion(String fileName) {
        File file = new File(fileName);
        System.out.println("fileName：" + fileName);
        BufferedReader reader = null;
        String version = "";
        String MatchVersion = "((?<=Autodesk Revit )\\d{4})";
        String finalStr ="";
        try {
            System.out.println("以行为单位读取文件内容，一次读一整行：");
            reader = new BufferedReader(new FileReader(file));
            String tempString = null;
            int line = 1;
            // 一次读入一行，直到读入null为文件结束
            while ((tempString = reader.readLine()) != null) {
                char[] strArr = tempString.toCharArray();
                //处理特殊字符
                for (int j = 0; j < strArr.length; j++) {
                    if ((int) strArr[j] == 0) {
                        strArr[j] = '*';
                    }
                }
                finalStr = String.valueOf(strArr);
                finalStr = finalStr.replace("*", "");
                Pattern pattern = Pattern.compile(MatchVersion);
                Matcher match = pattern.matcher(finalStr);
                if (match.find()) {
                    version = match.group(1);
                    break;
                }
                line++;
            }
            // 显示行号
            System.out.println("line " +  line+ ": " + finalStr);
            reader.close();
            return version;
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (reader != null) {
                try {
                    reader.close();
                } catch (IOException e1) {
                }
            }
        }
        return version;
    }
}
