将 Autoit 正则表达式转换为 C#

Question

我无法解决这个问题，我得到了这个搜索表达式

.*?(8986(.{8})8A4F03)

它在 autoit 中运行得非常快，并给了我 1 个结果，但如果我在 c# 中尝试它，它似乎会挂起。我也试过了

(8986(.{8})8A4F03)

它在 autoit 和 c# 中都非常有效，但给了我 2 个结果，但我只想要第一个结果。我已经阅读了 autoit 和 c# 的“备忘单”，但我就是不明白。

到目前为止的c#代码

if (File.Exists(file) == true)
        {
            FileStream inputFile = new FileStream(file, FileMode.Open , FileAccess.Read,FileShare.ReadWrite);
            byte[] byteBuffer = new byte[inputFile.Length];
            inputFile.Read(byteBuffer, 0, (int) inputFile.Length);
            inputFile.Dispose();
            StringBuilder client = new StringBuilder();
            for (int i = 0; i < byteBuffer.Length; i++)
            {
                client.Append(byteBuffer[i].ToString("X2"));
            }
            // Clipboard.SetText(client.ToString()); //get string to paste into regexbuddy

            Regex rx = new Regex(@".*?(8986(.{8})8A4F03)"); //works perfect in autoit but hangs here
            //Regex rx = new Regex(@"(8986(.{8})8A4F03)"); // too many groups + too many matches
            //Regex rx = new Regex(@"8986(.{8})8A4F03"); //one group but too many matches

            foreach (Match mx in rx.Matches(client.ToString()))
            {
                Console.WriteLine(mx);
                //Console.WriteLine(mx.Groups[1]);
            }
        }

我没有做出原始表达，我不声称知道它们是如何工作的

字符串的第一部分是

4D5A90000300000004000000FFFF0000B8000000000000004000000

我想要的结果是

6C040000

试试这个 C# sn-p：

string resultString = null;
resultString = Regex.Match(text, "(?<=8986).{8}(?=8A4F03)").Value;
