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

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 = ;//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
             }
         }

FolderBrowserDialog使用

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;
             }
         }
