Revit二次开发，获取模型版本信息

string path = @"C:xxx.rfa";//模型地址

BasicFileInfo fileInfo =BasicFileInfo.Extract(path);//引入Autodesk.Revit.DB.BasicFileInfo

MessageBox.Show(fileInfo.SavedInVersion); 

 该方法在Revit 2020下已失效。

以下这是在谷歌找到的模型版本信息获取方式，理论山兼容所有版本，亲测可用

  private string ReadFileVersion(string filePath)
        {
            string fileVersion = null;
            var rawData = GetRawBasicFileInfo(filePath);
            var rawString = System.Text.Encoding.Unicode.GetString(rawData);
            var fileInfoData = rawString.Split(new string[] { "", "
" }, StringSplitOptions.RemoveEmptyEntries);
            foreach (var item in fileInfoData)
            {
                if (item.StartsWith("Revit Build"))
                {
                    int colonIndex = item.IndexOf("k");
                    if (colonIndex > -1)
                    {
                        fileVersion = item.Substring(colonIndex + 1);
                        int bracketsIndex = fileVersion.IndexOf("(");
                        fileVersion = fileVersion.Substring(0, bracketsIndex);
                    }
                }   
            }
            return fileVersion;
