Question

我将从套接字（由于错误）获得的1行字符串转换为哈希：

     #the server-response: 
     $r = "8=FIX.4.4°9=77°35=0°34=98°49=COUNTERPARTY°52=20140531-22:45:04.752°56=FIXPUSHER°112=Testing°10=055"
     #convert to a hash:
     $hash = ConvertFrom-StringData -StringData ($r).Replace("°","`n")
     # let's try again..
     $hash.Clear() # or $hash = @{}
     $r = "8=FIX.4.4°9=77°35=0°34=98°49=COUNTERPARTY°52=20140531-22:45:04.752°56=FIXPUSHER°112=Testing°10=055"
     $hash = ConvertFrom-StringData -StringData ($r).Replace("°","`n")

（嗯？我必须找到一种重复错误的方法..）

现在我换了s.th.在我的程序中再次发送我的请求到服务器，我得到部分相同的行，特别是哈希的大多数键将返回。所以我试图清空那个哈希 - 但是没有任何东西真的有效：

     $hash = @{}

，也不

     $hash.Clear()

我总是得到错误（我的德语错误文本的英文翻译）：
elemet＆＃34; 8＆＃34;在线＆＃34; 8 = FIX.4.4＆＃34;已定义...
所有的沟通都从这部分开始。

如何重新使用我的$ hash-variable来分析服务器的响应？

请知道吗？提前谢谢，

我可以给你更多信息。错误发生在更大的循环中。如果我的脚本在调试模式下通过comd运行cmd，那么第一次（没有错误）只会滑过：

      $hash = ConvertFrom-StringData -StringData ($r).Replace("°","`n")

第二次时间（$ hash已被清空）同一行跳转到ConvertFrom-StringData，产生此错误文本：

（我的英文翻译）有什么想法吗？

PowerShell：清空哈希似乎不起作用:(
