標(biāo)題: C#上位機(jī)程序索引超出數(shù)組界限?

運(yùn)行上位機(jī)，十秒不到就崩，不知道怎么解決？求助

就是收到的數(shù)據(jù)沒那么多，或者分多次（分段）上傳了

那具體應(yīng)該怎么修改？

大佬們，代碼應(yīng)該怎么修改呀？

作者: Hephaestus 時(shí)間: 2022-5-10 21:17
增加item.SubItems的數(shù)量。

作者: silicon 時(shí)間: 2022-5-13 20:07
最后是用if(info.length>=7){}將傳感器代碼括起來解決問題的

作者: lhzw2001 時(shí)間: 2022-5-14 11:56
把工程傳上來看看

作者: yaoyao2022 時(shí)間: 2022-5-14 17:18
string[] info = data.Split('/'); 這個(gè)里面的' ' 改成雙引號

這樣會出錯(cuò)
