SharedPreferences 但在 c# Windows 表单应用程序 C# Visual Studio

Question

I'm creating a simple messages program, in which u can talk to other people.

Currently, I'm working on the login screen and I want to create a "remember me" option which will save your credentials the next time u enter the app. I worked a bit with android Studio,and Unity, and they both use something called SharedPreferences , I used it and it's great. So I wanna know if there is a SharedPreferences for C# and how to use it on a Windows Form App.

Any help is accepted.

Answer 1

In winforms, we usually use Settings to keep the user setting info.

To achieve the requirement, you can refer to the following steps:

1.Click "Project" and choose "Setting Properties…", then choose "Settings"

2.Add new setting in "Settings"

3.Try the following code:

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    // Save the current state of the checkbox
    Properties.Settings.Default.cb = checkBoxRememberMe.Checked;
    Properties.Settings.Default.str = textBox1.Text;
    Properties.Settings.Default.Save();
}

private void Form1_Load(object sender, EventArgs e)
{
    // load checkbox state from settings
    checkBoxRememberMe.Checked = Properties.Settings.Default.cb;
    textBox1.Text = Properties.Settings.Default.str;
}
