hi wilbyang,
lets say you have one column which display name of images, and that is editable and user rename it, and there is button OK, so on OK click you write your code. Loop through all rows and by using System.IO.File.Move(sourcefileName, destFileName) you can rename all images.

Hi wilbyang,

I have made a sample for you which can rename all jpg files in a folder to MyPic[X ].jpg
"X " will be increase by 1 for each file.
public void RenameAllFile(string folderPath)
{
DirectoryInfo dirInfo = new DirectoryInfo(folderPath);
FileInfo[] fileInfo = dirInfo.GetFiles("*.jpg");
for (int i = 0; i < fileInfo.Length; i++)
{
fileInfo[i].MoveTo(folderPath + "\\MyPic" + i.ToString() + ".jpg");
}
}
.NET doesn't offer Rename method. So I have to use MoveTo method. Once the destination folder is the same as the source folder. The file will be renamed.

I think this will help you to solve the problem.

If you have anything unclear, please feel free to tell me.

Sincerely,
Kira Qian
