Last updated at Posted at 2020-01-02

概要

cscの作法、調べてみた。
ファイルダイアログやってみた。

サンプルコード

using System;
using System.Windows.Forms;
using System.Drawing;

class form1: Form {
	form1() {
		Text = "open";
		ClientSize = new Size(200, 200);
		Button btn1 = new Button();
		btn1.Location = new Point(50, 50);
		btn1.Text = "test";
		btn1.Click += btn1_Click;
		Controls.AddRange(new Control[] {
			btn1
		});
	}
	void btn1_Click(object sender, System.EventArgs e) {
		string fileContent = string.Empty;
		string filePath = string.Empty;
		using (OpenFileDialog openFileDialog = new OpenFileDialog())
		{
			openFileDialog.InitialDirectory = "c:\\";
			openFileDialog.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
			openFileDialog.FilterIndex = 2;
			openFileDialog.RestoreDirectory = true;
			if (openFileDialog.ShowDialog() == DialogResult.OK)
			{
				filePath = openFileDialog.FileName;
				MessageBox.Show(filePath);
			}
		}
	}
	[STAThread]
	public static void Main() {
		Application.Run(new form1());
	}
}
