How to use settings in Visual C#

问题:

I have been a VB.net developer for a long time and changed recently to C#. When I was using VB.net, to call user settings, I just need to create a new setting using the designer and then call it from code with the My namespace.
Here's the code
My.settings.anysetting
I can change or get data from it. However in C# the My keyword doesn't work, so what can I do to call settings??

回答1:

Settings are stored under the Application folder and as such, use that as their namespace.

int myInt = Properties.Settings.Default.myVariable;
Properties.Settings.Default.myVariable = 12;
Properties.Settings.Default.Save();

Using Settings in C#

回答2:

Kinda like this:

this.BackColor = Properties.Settings.Default.myColor;

回答3:

// Retrieving connection string from Web.config.
String connStringMSQL = WebConfigurationManager.ConnectionStrings["andi_msql"].ToString();

In my case this was for my connectionStrings setting but depending on what node your setting is in you can change this accordingly.

Hope this helps
