C#读取某台服务器的硬件信息(winform实现)
总的来说 FRAMEWORK 好像不提供这些功能,如果你想调用的话,就得C#内调 USR32DLL 这些系统内部的DLL文件
下面是我以前复制来的,总的道理就是 调用USER32DLL 然后用它里面的函数初始化C#结构,里面有各种硬件信息

都存在服务器上, cs程序端也是通过URL形式访问,如SystemNetWebClient类可以读取远程, 本质上和BS结构一样,只不过BS结构是浏览器帮你实现读取远程这一步。
当然,服务器端得架设一个web站点提供服务。
在客户端服务器的WCF服务代码里调用ReadFile方法,传入公司服务器上文件的物理路径,即可在客户端服务器端获取到公司服务器文件的二进制流了,之后可以保存下来,也可以直接回发给客户客户端
可以用SQL语句来获取文件:
select Tc from openrowset(bulk N'D:\DB_Backup\E5KST01\audit_trail_20130419bak', single_blob) T(c)
lz要先知道什么是socket,它是TCP/IP协议的API。再上层是http udp之类传输报文协议。而什么是服务器,如你所说tomcat服务器,他是一个http(s)服务器。处理由客户发送的HTTP报文。并返回报文给客户。
简单来说,http就是socket的一个封装。所以c语言使用socket理所当然能访问任何服务器。至于使用什么格式,你可以看看HTTP报文格式。
目前,C语言主要用于嵌入式软件的开发,很少用C语言开发PC软件。不知道帅哥是不是要在PC上用C语言操作Execl文件、操作原因。
既然要操作,请试一下下面的方法:
A, 用Excel打开要读取的excel文件。
B, 点击Excel菜单“文件”-> “另存为”,选择文件类型为“CSV(逗号分隔)”。这样,原来的excel文件会被另存为csv格式的文件,该文件是文本文件,
可以用文本文件编辑工具打开的。原excel文件的每一行记录,被转换为一行文本了。一行记录各列的值,用逗号隔开了。
C, 用C语言的文件IO函数接口,读取上面文本文件即可。
