Vulnerability Change this code to not construct the path from user-controlled data

I changed the code based on SonarQube suggestion. but still showing vulnerability. someone please help us.

byte[] blobData = blob.Buffer;
				strTempPath = strTempPath + @"\jpeg";                
                string strNewFilePath = string.Empty;
                strNewFilePath = Path.GetFullPath(System.IO.Path.Combine(strTempPath, savedFilePath.Substring(savedFilePath.LastIndexOf(@"\") + 1)));
                string fullDestDirPath = Path.GetFullPath(strTempPath + Path.DirectorySeparatorChar);                
                if (strNewFilePath.StartsWith(fullDestDirPath, StringComparison.Ordinal)) {
                    blobData = File.ReadAllBytes(strNewFilePath);
                } else
                    throw new IOException("Attempting to read bytes");
