我需要創建一些接口來從iButton讀取數據。實際上,它的工作原理是這樣的:用戶將帶有磁鐵的小吊墜應用於iButton設備 - >登錄他。用戶帶走吊墜 - 註銷。更改字符串時引發事件
我的問題是,我知道如何重新登錄,通過簡單:
public static void sp_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
if (sp.ReadLine() == "logout")
{
logoutUser();
}
else
{
//put data into nonstatic textbox from another window
// or raise some event which will listen to changes in data and put string into textbox
}
}
但我怎麼能提高時,事件數據=「註銷」(例如A0019293881,如PIN碼)!
