c#中的几种Dialog

1、OpenFileDialog

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

            openFile.InitialDirectory = @"E:";//打开初始目录
            openFile.Title = "选择打开文件";//窗体标题
            openFile.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";//过滤条件
            openFile.FilterIndex = 2;//获取第二个过滤条件开始的文件
            openFile.Multiselect = true;//是否多选

            if (openFile.ShowDialog() == DialogResult.OK)//页面弹出判断是否点击确定按钮
            {
                //没勾选多选时
                //string filename = openFile.FileName;
                //string name=openFile.SafeFileName; 

                //勾选多选时
                for (int i = 0; i < openFile.SafeFileNames.Length; i++)//获取文件名，拓展名
                {
                    rictbo.Text += openFile.SafeFileNames[i] + "
";
                }
                for (int i = 0; i < openFile.FileNames.Length; i++)//获取文件全部路径
                {
                    rictbo.Text += openFile.FileNames[i] + "
";
                }
            }
        }

2、SaveFileDialog

 SaveFileDialog与OpenFileDialog属性基本相同就简单写了

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

            saveFile.InitialDirectory= @"E:";//打开初始目录
            saveFile.Title = "选择保存文件";
            saveFile.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*|图片(.jpg)|*.jpg";//过滤条件
            saveFile.FilterIndex = 1;//获取第二个过滤条件开始的文件拓展名
            saveFile.FileName = "新建";//默认保存名称
            
            if (saveFile.ShowDialog()==DialogResult.OK)//页面弹出判断是否点击确定按钮
            {
                string txt = rictbo.Text;
                //写入
                File.WriteAllText(saveFile.FileName, txt);
            }
        }
    }

3、FolderBrowserDialog

这个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 = "选择匹配目录"; ;//左上角提示
            string path = string.Empty;

            if (dialog.ShowDialog() == DialogResult.OK)
            {
                path = dialog.SelectedPath;//获取选中文件路径
            }
        }

4、FontDialog

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

            fontDialog.ShowColor=true;//显示颜色选择
            fontDialog.Font = rictbo.Font;
            fontDialog.Color = rictbo.ForeColor;

            if (fontDialog.ShowDialog()==DialogResult.OK)//页面弹出判断是否点击确定按钮
            {
                rictbo.Font = fontDialog.Font;//字体
                rictbo.ForeColor = fontDialog.Color;//字体颜色
            }
        }

5、ColorDialog

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

            //colorDialog.AllowFullOpen = false;是否启用自定义颜色
            colorDialog.Color = rictbo.ForeColor;
            if (colorDialog.ShowDialog()==DialogResult.OK)
            {
                rictbo.ForeColor = colorDialog.Color;
            }
        }
