如何在 c# 中添加 Properties.Settings.Default

Question

I am not able to write "Properties.Settings.Default". It is not coming in the dropdown list. Is there any namespace that we can add?

Answer 1

Add your project namespace to the Properties namespace. The default namespace defined in the project settings.

For instance if your project default namespace is MyApp.

MyApp.Properties.Settings.Default

Answer 2

Make sure you are on the same namespace and try to access the properties like this :

namespace.Properties.Settings.Default

or if you are on different namespace don't forget to use

using namespace

Answer 3

An additional hint on top of the above answers:

Go to solution explorer -> Properties folder -> Settings.settings -> Settings.Designer.cs file

and see which namespace is being used there. Ensure that you are using this namespace in your code file as others have suggested

Answer 4

Once you setup your environment in the settings under properties of the app. You want to reference it to the project like this:

using App.Properties.Settings

Then in the code you write you can use as example:

userName.Settings.Default

In this case userName is set within the settings.

Answer 5

1. Set your Setting in your project go to Project => property => go to setting

2. Set your element (string,int, ecc...)

3. Save from program all values

Properties.Settings.Default.User = txtUser.Text; Properties.Settings.Default.Password = txtPass.Text; Properties.Settings.Default.Save();

if you use Windows 10, this is the directory of setting Values: C:\\Users\\AppData\\Local<ProjectName.exe_Url_somedata>\\1.0.0.0<filename.config>
