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] + "\r\n";
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] + "\r\n";
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         }

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             }
11         }
