C # webbrowser automatic form submission

Every day, the company needs to log on to several specific websites. It is uncomfortable to lose the account password. use C # webbrowser to automatically fill out the table and submit the Logon Request. the result shows that there is a login button in the form of the website to be logged on without a name. The form is as follows:

C # code

<Form ID = "f_login" name = "f_login" target = "_ top" method = "Post" onsubmit = "Return checkinput (); "> <input type =" text "name =" ID "name =" ID "> <input type =" password "id =" passwd "name =" passwd "> <Input type = "Submit" tabindex = "6" Title = "Logon" value = ""/> </form>

 

Because no logon button name exists

You can directly submit without clicking the "Log on" button. For example, webbrowser1.document. getelementbyid ("f_login"). invokemember ("Submit ");
