Okay, I'm a newbie in C# but I need to create a simple GUI, but I don't have Visual Studio (I use Geany and Mono).
The problem is, when I tried the following code that I found by Google:
using System;
using System.Windows.Forms;
using System.ComponentModel;
using System.Drawing;
public class FirstForm : Form
{
private Container components;
private Label howdyLabel;
public FirstForm()
{
InitializeComponent();
}
private void InitializeComponent()
{
components = new Container ();
howdyLabel = new Label ();
howdyLabel.Location = new Point (12, 116);
howdyLabel.Text = "Howdy, Partner!";
howdyLabel.Size = new Size (267, 40);
howdyLabel.AutoSize = true;
howdyLabel.Font = new Font (
"Microsoft Sans Serif",
26, System.
Drawing.FontStyle.Bold);
howdyLabel.TabIndex = 0;
howdyLabel.Anchor = AnchorStyles.None;
howdyLabel.TextAlign = ContentAlignment.MiddleCenter;
Text = "First Form";
Controls.Add (howdyLabel);
}
public static void Main()
{
Application.Run(new FirstForm());
}
}
I just get these errors when trying to compile:
C:\C#\test2.cs(2,14): error CS0234: The type or namespace name 'Windows' does not exist in the namespace 'System'. Are you missing an assembly reference?
C:\C#\test2.cs(4,14): error CS0234: The type or namespace name 'Drawing' does not exist in the namespace 'System'. Are you missing an assembly reference?
C:\C#\test2.cs(9,11): error CS0234: The type or namespace name 'Label' could not be found. Are you missing a using directive or an assembly reference?
Compilation failed: 3 error(s), 0 warnings
I downloaded both DLL's, but I don't know what to do next. Link to the code: http://www.informit.com/articles/article.aspx?p=27316

You are using WinForm on mono, maybe will be better use GTK#, however if you want use WinForms on mono it is possible. Take a look at this documentation for more information .
You have to use gmcs
in this way to compile your program :
gmcs Program.cs -r:System.Windows.Forms.dll

You're using the Microsoft WinForms UI library, which Mono does not include.
You need to use a Mono-compatible UI library, such as GTK#.
You can also use the Mono port of WinForms.
