c# 创建文件/文件夹对话框

1.创建选择文件夹对话框

 1 List<FileInfo> ImageFileInfo = new List<FileInfo>(); //文件信息
 2 FolderBrowserDialog fbd = new FolderBrowserDialog(); //选择文件夹
 3             if (fbd.ShowDialog() == DialogResult.OK)
 4             {
 5                 directory.Text = fbd.SelectedPath; //显示目录
 6                 CheckImageFile（fbd.SelectedPath，True) //根目录还是全部目录

7  }
 8 void CheckImageFile(string TargetPath, bool TopOption)
 9         {
10             if (TargetPath == "")
11             {
12                 return;
13             }
14 
15             var Option = TopOption == true ? SearchOption.TopDirectoryOnly : SearchOption.AllDirectories;
16 
17             DirectoryInfo di = new DirectoryInfo(TargetPath);
18             InspectImageFileInfo.Clear();
19             InspectImageFileInfo.AddRange(di.GetFiles("*.jpg", Option));
20             InspectImageFileInfo.AddRange(di.GetFiles("*.jpeg", Option));
21             InspectImageFileInfo.AddRange(di.GetFiles("*.bmp", Option));
22             InspectImageFileInfo.AddRange(di.GetFiles("*.png", Option));
23 
24             lbl_ImageCount.Text = "Image Count : " + InspectImageFileInfo.Count;
25         }

2.创建选择文件对话框

using System.Windows.Forms;

1             OpenFileDialog dlg = new OpenFileDialog();
2             dlg.Filter = "图片文件(*.png;*.jpg;*.bmp;*.jpeg)|*.png;*.jpg;*.bmp;*.jpeg"; //过滤文件后缀
3             dlg.Multiselect = true;  //是否可以选择多张图片
4             if (dlg.ShowDialog() == DialogResult.OK)
5             {
6                 this.PicPath = dlg.FileName;  //获取单个文件名
7             }

 1 　　　　　　　　
List<string> FileNames = new List<string>();
 OpenFileDialog dlg = new OpenFileDialog();
 2             dlg.Filter = "图片文件(*.png;*.jpg;*.bmp;*.jpeg)|*.png;*.jpg;*.bmp;*.jpeg";
 3             dlg.Multiselect = true;
 4             if (dlg.ShowDialog() == DialogResult.OK)
 5             {
 6                 this.PicPath = dlg.FileName; //获取首个文件名
 7             }   
 8             for(int i=0;i<dlg.FileNames.Length;i++) //遍历所有文件名
 9             {
10                 FileNames.Add(dlg.FileNames.GetValue(i).ToString());  //加入List<string>
11             }
