以上這部分是用Visual Basic 讀取托利多電子秤重量的，用的是Socket 網口方式。
然后我在轉化成C#的時候，提示我連接被拒絕。
有沒有高手看看怎么把這段VB的代碼弄成C#的，并且正常作業。
謝謝謝謝謝謝。

連接是否要發送特定的指令，你看看通信協議uj5u.com熱心網友回復：
關鍵VB代碼中也沒什么特殊指令啊，直接用一個Socket控制元件就連接上去了。總不會到了C#下面就要用特殊指令了吧。

用socket除錯助手試試，https://www.jianshu.com/p/3e16e5dab8a6轉載請註明出處，本文鏈接：https://www.uj5u.com/net/60529.html
