C # store values in ini format (for example, the user name and logon number on the login interface)

This is the first blog post. In the future, I will summarize and share all the things I have found through my own materials during development, so that I can take a look at them later ~~~

PS: Of course, I feel like I am still a small dish ~ For the great gods, the content may be relatively simple ~ A lot of things are also sorted out on the Internet. It would be a great honor for me to help you a little bit.

First, if you have created a login interface, you must enter the "user name" [username] and password to log on. To avoid entering the user name every time you open the system, now we need to implement a file storage function,

The file will be stored in ". ini" format:

Write File:

1 [DllImport("kernel32")]2 private static extern long WritePrivateProfilesString(string section,string key,string val,string filepath);3 private static void WriteToIni(string name,string key,string value)4 {5     WritePrivateProfilesString(name,key,value,Directory.GetCurrentDirectory()+@"\User.ini");6 }

Write

Read data from a file:

1 [DllImport("kernel32")]2 private static extern int GetPrivateProfileString(string section,string key,string def,StringBuilder returnval,int size,string iniPath);3 private string GetStringIni(string section,string key)4 {5      StringBuilder strbuider=new StringBuilder(1024);6      string def=null;7        GetPrivateProfileString(section,key,def,strbuilder,1024,Directory.GetCurrentDirectory()+@"\User.ini");8      return strbuilder.ToString();9 }
