C＃如何遍历Properties.Settings.Default.Properties更改值 [英] C# How to loop through Properties.Settings.Default.Properties changing the values

问题描述

我有以下代码：

foreach (SettingsProperty currentProperty in Properties.Settings.Default.Properties)
{
    if (Double.TryParse(GenerateValue()), out result))
    {
        currentProperty.DefaultValue = result.ToString();

        Properties.Settings.Default.Save();
    }
}

它从mysql数据库获取新值。如果我添加一个MessageBox.Show来显示新值，则似乎工作正常，但实际上并没有保存它。我认为这是因为我正在将值分配给变量...是否有某种方法可以做到这一点？

It gets the new value from a mysql database. If I add a MessageBox.Show to show the new value it seems to be working fine but it doesn't actually save it. I assume this is because I am assigning the value to a variable...is there some way to do this?

Properties.Settings.Default.IndexOf(currentProperty.name).DefaultValue = result

推荐答案

这可能起作用：

foreach (SettingsProperty  currentProperty in Properties.Settings.Default.Properties)
{
    Properties.Settings.Default[currentProperty.Name] = result.ToString();
    Properties.Settings.Default.Save();
}

请记住，属性应具有范围 User才能保存

Keep in mind that properties should have scope 'User' in order to be saved.
