CSCとFSCのメモ

(form1.cs)
using System;
using System.Drawing;
using System.Windows.Forms;

namespace MyFrmApp
{
    public class MyForm : Form
    {
        public MyForm()
        {
            Label label = new Label();
            label.Text = "Welcome to C#!";
            label.Font = new Font("Geneva",18,FontStyle.Regular);
            label.Height = 30;
            label.Width = 300;
            this.Controls.Add(label);
            this.Width = 300;
            this.Height = 200;
        }
    }
}

(main1.cs)

using System;

using System.Windows.Forms;

namespace MyFrmApp

{

    class Program

    {

        [STAThread]

        private static void Main(string[] args)

        {

            Application.Run(new MyForm());

        }

         

    }

}

上記ファイルを同一フォルダにおき

csc /out:form1.exe *.cs で実行ファイルができる！
