将多个键/值对保存到 app.config

发布于 2025-01-12 17:28:45 字数 857 浏览 0 评论 0原文

我正在开发一个 winform 应用程序，我在 app.config 文件中存储一些设置（用户名、电子邮件、邮政编码）。

public static void Set(string key, string value)
    {

        var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

        var entry = config.AppSettings.Settings[key];
        if (entry == null)
            config.AppSettings.Settings.Add(key, value);
        else
            config.AppSettings.Settings[key].Value = value;

        config.Save(ConfigurationSaveMode.Modified);
    }

我想将设置保存到 app.config 文件中。所以我有这个代码。问题是：我只能使用变量密钥一次......所以我无法保存电子邮件和邮政编码。我正在考虑使用数组，但我不知道如何实现它。有什么建议吗？

private void button_savesettings_Click(object sender, EventArgs e)
    {
        string key = "username";
        string username = textBox_user.Text;

        Set(key, username);

        

    }

非常感谢！

I'm working on an winform application, where I store some setting (username, email, zipcode) in the app.config file.

public static void Set(string key, string value)
    {

        var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

        var entry = config.AppSettings.Settings[key];
        if (entry == null)
            config.AppSettings.Settings.Add(key, value);
        else
            config.AppSettings.Settings[key].Value = value;

        config.Save(ConfigurationSaveMode.Modified);
    }

I'd like to save the settings to the app.config file. So I have this code.
Problem is: I can only use the variable key once.... So i can't saven the email and zipcode.
I was thinking of working with an array, but I have no idea on how to implement this. Any suggestions?

private void button_savesettings_Click(object sender, EventArgs e)
    {
        string key = "username";
        string username = textBox_user.Text;

        Set(key, username);

        

    }

Many thanks!

一个简单的循环就可以解决这个问题

void SetAppSettingsValues(Dictionary<string, string> dict)
{
    // bit of validation
    if (dict == null || !dict.Any())
        return;

    var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

    foreach (var key in dict.Keys)
    {
        var configItem = config.AppSettings.Settings[key];

        if (configItem == null)
            config.AppSettings.Settings.Add(key, dict[key].Value);
        else
            config.AppSettings.Settings[key].Value = dict[key].Value;
    }

    config.Save(ConfigurationSaveMode.Modified);
}

A simple loop will solve the problem

void SetAppSettingsValues(Dictionary<string, string> dict)
{
    // bit of validation
    if (dict == null || !dict.Any())
        return;

    var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

    foreach (var key in dict.Keys)
    {
        var configItem = config.AppSettings.Settings[key];

        if (configItem == null)
            config.AppSettings.Settings.Add(key, dict[key].Value);
        else
            config.AppSettings.Settings[key].Value = dict[key].Value;
    }

    config.Save(ConfigurationSaveMode.Modified);
}
