C# – How to get the application specific data folder (ProgramData)

appdatacprogramdatawinforms

I need to read and write files that contain application specific data, shared between all the users.

I tried to use Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData), but it returns only C:\ProgramData.

My question is :

Does it exist a system like Path.GetDirectoryName(Application.UserAppDataPath), which will give me the exact folder to write, according to my application name and version?

Or is ProgramData not the right place to do that.

Thanks.

I think CommonApplicationData is exactly what you're looking for, as it's the global folder for all applications which are not bound to a user.

var commonpath = GetFolderPath(SpecialFolder.CommonApplicationData);
var path = Path.Combine(commonpath, "YourAppName\\YourApp.exe");
try { 
    Process.Start(path);
    // or put data there or whatever
} 
catch (Exception ex)
{
    MessageBox.Show(path);
}

There's also SpecialFolder.LocalApplicationData for user-bound data.

C# – How to get the index of the current iteration of a foreach loop

Ian Mercer posted a similar solution as this on Phil Haack's blog:

foreach (var item in Model.Select((value, i) => new { i, value }))
{
    var value = item.value;
    var index = item.i;
}

This gets you the item (item.value) and its index (item.i) by using this overload of LINQ's Select:

the second parameter of the function [inside Select] represents the index of the source element.

The new { i, value } is creating a new anonymous object.

Heap allocations can be avoided by using ValueTuple if you're using C# 7.0 or later:

foreach (var item in Model.Select((value, i) => ( value, i )))
{
    var value = item.value;
    var index = item.i;
}

You can also eliminate the item. by using automatic destructuring:

<ol>
foreach ((MyType value, Int32 i) in Model.Select((value, i) => ( value, i )))
{
    <li id="item_@i">@value</li>
}
</ol>

C# – How to save application settings in a Windows Forms application

If you work with Visual Studio then it is pretty easy to get persistable settings. Right click on the project in Solution Explorer and choose Properties. Select the Settings tab and click on the hyperlink if settings doesn't exist.

Use the Settings tab to create application settings. Visual Studio creates the files Settings.settings and Settings.Designer.settings that contain the singleton class Settings inherited from ApplicationSettingsBase. You can access this class from your code to read/write application settings:

Properties.Settings.Default["SomeProperty"] = "Some Value";
Properties.Settings.Default.Save(); // Saves settings in application configuration file

This technique is applicable both for console, Windows Forms, and other project types.

Note that you need to set the scope property of your settings. If you select Application scope then Settings.Default.<your property> will be read-only.
