解决方案
解决方案二：
dbobj.getcom("insertinto"+intoSQL);改为：dbobj.getcom(intoSQL);试试看
解决方案三：
1楼正解，还有你下断点调试，把执行的sql字符串拿出来单独调试就明白了。
解决方案四：
你的代码看~~最后执行出来的SQL应该是~~"insertintoinsertintowebabout(nFile,nTitle,nHtmlText)values。。。。“SQL明显语法就不对了嘛！！一楼正解哦！！！
解决方案五：
关键字'insert'附近有语法错误。]报这样的错误肯定是SQL语句写错了一般如果你不知道语句错在哪里调试复制intoSQL字符串到数据库执行下就知道了
解决方案六：
stringintoSQL="";intoSQL="insertintowebabout(nFile,nTitle,nHtmlText)values(";intoSQL+=""+txtid.Text+",";intoSQL+="'"+txtitle.Text+"',";intoSQL+="'"+txtContent.Text+"')";stringtest=intoSQL;dbobj.getcom(intoSQL);//这行设置断点，看看上一行的test值是什么？你就会明白了
很简单
