c#中的几种Dialog

1、OpenFileDialog

 1         private void FileOpen_Click(object sender, EventArgs e)
 2         {
 3             OpenFileDialog openFile = new OpenFileDialog();//创建OpenFileDialog对象
 4 
 5             openFile.InitialDirectory = @"E:";//打开初始目录
 6             openFile.Title = "选择打开文件";//窗体标题
 7             openFile.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";//过滤条件
 8             openFile.FilterIndex = 2;//获取第二个过滤条件开始的文件
 9             openFile.Multiselect = true;//是否多选
10 
11             if (openFile.ShowDialog() == DialogResult.OK)//页面弹出判断是否点击确定按钮
12             {
13                 //没勾选多选时
14                 //string filename = openFile.FileName;
15                 //string name=openFile.SafeFileName; 
16 
17                 //勾选多选时
18                 for (int i = 0; i < openFile.SafeFileNames.Length; i++)//获取文件名，拓展名
19                 {
20                     rictbo.Text += openFile.SafeFileNames[i] + "
";
21                 }
22                 for (int i = 0; i < openFile.FileNames.Length; i++)//获取文件全部路径
23                 {
24                     rictbo.Text += openFile.FileNames[i] + "
";
25                 }
26             }
27         }

2、SaveFileDialog

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

 1         private void button1_Click(object sender, EventArgs e)
 2         {
 3             SaveFileDialog saveFile = new SaveFileDialog();
 4 
 5             saveFile.InitialDirectory= @"E:";//打开初始目录
 6             saveFile.Title = "选择保存文件";
 7             saveFile.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*|图片(.jpg)|*.jpg";//过滤条件
 8             saveFile.FilterIndex = 1;//获取第二个过滤条件开始的文件拓展名
 9             saveFile.FileName = "新建";//默认保存名称
10             
11             if (saveFile.ShowDialog()==DialogResult.OK)//页面弹出判断是否点击确定按钮
12             {
13                 string txt = rictbo.Text;
14                 //写入
15                 File.WriteAllText(saveFile.FileName, txt);
16             }
17         }
18     }

3、FolderBrowserDialog

这个使用的不多日后用到再添加

 1         private void button2_Click(object sender, EventArgs e)
 2         {
 3             FolderBrowserDialog dialog = new FolderBrowserDialog();
 4             dialog.Description = "选择匹配目录"; ;//左上角提示
 5             string path = string.Empty;
 6 
 7             if (dialog.ShowDialog() == DialogResult.OK)
 8             {
 9                 path = dialog.SelectedPath;//获取选中文件路径
10             }
11         }

FolderBrowserDialog使用

4、FontDialog

 1         private void button3_Click(object sender, EventArgs e)
 2         {
 3             FontDialog fontDialog = new FontDialog();
 4 
 5             fontDialog.ShowColor=true;//显示颜色选择
 6             fontDialog.Font = rictbo.Font;
 7             fontDialog.Color = rictbo.ForeColor;
 8 
 9             if (fontDialog.ShowDialog()==DialogResult.OK)//页面弹出判断是否点击确定按钮
10             {
11                 rictbo.Font = fontDialog.Font;//字体
12                 rictbo.ForeColor = fontDialog.Color;//字体颜色
13             }
14         }

5、ColorDialog

 1         private void color_Click(object sender, EventArgs e)
 2         {
 3             ColorDialog colorDialog = new ColorDialog();
 4 
 5             //colorDialog.AllowFullOpen = false;是否启用自定义颜色
 6             colorDialog.Color = rictbo.ForeColor;
 7             if (colorDialog.ShowDialog()==DialogResult.OK)
 8             {
 9                 rictbo.ForeColor = colorDialog.Color;
10             }
