在C#中保存用户设置 [英] Save user settings in c#

问题描述

我尝试将用户设置保存在c#中.

i try to save user settings in c#.

我可以读取该值并将其放在文本框中，但不能更改它.

I can read the value and put it in a textbox but i can not change it.

这是我的WindowsForm，带有一个文本框和一个保存按钮:

This is my WindowsForm with an textbox and a save button:

    namespace tool
{
    public partial class Form4 : Form
    {
        string source = Properties.Settings.Default.Source;
        public Form4()
        {
            InitializeComponent();
        }

        private void Form4_Load(object sender, EventArgs e)
        {
            textBox1.Text = source;
        }

        private void textBox1_TextChanged(object sender, EventArgs e)
        {

        }

        private void save_Click(object sender, EventArgs e)
        {
            Properties.Settings.Default.Source = source;
            Properties.Settings.Default.Save();
            Application.Exit();
        }
    }
}

这是一张带有我的设置的图片:

And here is a picture with my settings:

我希望有人能提出一个主意:-)

推荐答案

尝试一下:

private void save_Click(object sender, EventArgs e)
{
   Properties.Settings.Default.Source = textBox1.Text;
   Properties.Settings.Default.Save();
   Application.Exit();
}

您需要使用文本框中当前使用的内容，而不是您的成员变量.

You need to use what is currently in the text box, not your member variable.

或者您可以将此事件更改为如下(然后您无需修改​​以上内容):

Or you can change this event to be as follows (and then you don't have to modify the above):

private void textBox1_TextChanged(object sender, EventArgs e)
{
   source = textBox1.Text;
}
