我正在.NETFramework4.5上创建一个应用程序
每当我想加载app config值(appsettings部分)并写入更改时,如果刷新该部分,就看不到我的更改。我做错什么了?我该怎么解决呢?
代码

    private void LoadConfig()
    {
        NameValueCollection appSettings = ConfigurationManager.AppSettings;
        for (int i = 0; i < appSettings.Count; i++)
        {
            switch (appSettings.GetKey(i))
            {
                case "initialCatalog":
                    txtInitialCatalog.Text = appSettings.GetValues(i)[0];
                    break;
                case "dataSource":
                    txtDatasource.Text = appSettings.GetValues(i)[0];
                    break;
                case "userName":
                    txtUsername.Text = appSettings.GetValues(i)[0];
                    break;
                case "password":
                    txtPassword.Text = appSettings.GetValues(i)[0];
                    break;
                case "portalUrl":
                    txtUrl.Text = appSettings.GetValues(i)[0];
                    break;
            }
        }
    }

    private void SaveConfig()
    {
        System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        KeyValueConfigurationCollection appSettings = config.AppSettings.Settings;
        appSettings["initialCatalog"].Value = txtInitialCatalog.Text;
        appSettings["dataSource"].Value = txtDatasource.Text;
        appSettings["userName"].Value = txtUsername.Text;
        appSettings["password"].Value = txtPassword.Text;
        appSettings["portalUrl"].Value = txtUrl.Text;
        config.Save(ConfigurationSaveMode.Modified);
        ConfigurationManager.RefreshSection("appSettings");
    }

app.config文件
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
  </startup>
  <appSettings>
    <add key="initialCatalog" value="a" />
    <add key="dataSource" value="b" />
    <add key="password" value="c" />
    <add key="userName" value="d" />
    <add key="portalUrl" value="e" />
    <add key="poolingTime" value="60000" />
    <add key="ClientSettingsProvider.ServiceUri" value="" />
  </appSettings>

当表单被激活时,我调用readconfig()并在按下按钮(确定或应用)时保存数据我关闭应用程序我重新运行它,但没有对app.config文件进行任何更改
有什么想法吗???

最佳答案

我认为发生的情况是,您正在visual studio中进行测试,它会将app.config复制到调试/发布目录,并将其重命名为application.vshost.exe.config,每次启动应用程序时,它都会重置。请尝试在visual studio外部运行可执行文件,该文件将使用yourcapplication.exe.config文件,并查看该文件是否适合您。如果我在visual studio之外运行应用程序,则您的代码对我有效,并在应用程序重新启动时保留您的更改。
