c#中的幾種Dialog

1、OpenFileDialog

        private void FileOpen_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFile = new OpenFileDialog();//創建OpenFileDialog對象

            openFile.InitialDirectory = @"E:\";//打開初始目錄
            openFile.Title = "選擇打開文件";//窗體標題
            openFile.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";//過濾條件
            openFile.FilterIndex = 2;//獲取第二個過濾條件開始的文件
            openFile.Multiselect = true;//是否多選

            if (openFile.ShowDialog() == DialogResult.OK)//頁面彈出判斷是否點擊確定按鈕
            {
                //沒勾選多選時
                //string filename = openFile.FileName;
                //string name=openFile.SafeFileName; 

                //勾選多選時
                for (int i = 0; i < openFile.SafeFileNames.Length; i++)//獲取文件名，拓展名
                {
                    rictbo.Text += openFile.SafeFileNames[i] + "\r\n";
                }
                for (int i = 0; i < openFile.FileNames.Length; i++)//獲取文件全部路徑
                {
                    rictbo.Text += openFile.FileNames[i] + "\r\n";
                }
            }
        }

2、SaveFileDialog

 SaveFileDialog與OpenFileDialog屬性基本相同就簡單寫了

        private void button1_Click(object sender, EventArgs e)
        {
            SaveFileDialog saveFile = new SaveFileDialog();

            saveFile.InitialDirectory= @"E:\";//打開初始目錄
            saveFile.Title = "選擇保存文件";
            saveFile.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*|圖片(.jpg)|*.jpg";//過濾條件
            saveFile.FilterIndex = 1;//獲取第二個過濾條件開始的文件拓展名
            saveFile.FileName = "新建";//默認保存名稱
            
            if (saveFile.ShowDialog()==DialogResult.OK)//頁面彈出判斷是否點擊確定按鈕
            {
                string txt = rictbo.Text;
                //寫入
                File.WriteAllText(saveFile.FileName, txt);
            }
        }
    }

 

3、FolderBrowserDialog

這個使用的不多日后用到再添加

        private void button2_Click(object sender, EventArgs e)
        {
            FolderBrowserDialog dialog = new FolderBrowserDialog();
            dialog.Description = "選擇匹配目錄"; ;//左上角提示
            string path = string.Empty;

            if (dialog.ShowDialog() == DialogResult.OK)
            {
                path = dialog.SelectedPath;//獲取選中文件路徑
            }
        }

4、FontDialog

        private void button3_Click(object sender, EventArgs e)
        {
            FontDialog fontDialog = new FontDialog();

            fontDialog.ShowColor=true;//顯示顏色選擇
            fontDialog.Font = rictbo.Font;
            fontDialog.Color = rictbo.ForeColor;

            if (fontDialog.ShowDialog()==DialogResult.OK)//頁面彈出判斷是否點擊確定按鈕
            {
                rictbo.Font = fontDialog.Font;//字體
                rictbo.ForeColor = fontDialog.Color;//字體顏色
            }
        }

5、ColorDialog

        private void color_Click(object sender, EventArgs e)
        {
            ColorDialog colorDialog = new ColorDialog();

            //colorDialog.AllowFullOpen = false;是否啟用自定義顏色
            colorDialog.Color = rictbo.ForeColor;
            if (colorDialog.ShowDialog()==DialogResult.OK)
            {
                rictbo.ForeColor = colorDialog.Color;
            }
        }
