Visual C#: Move multiple files with the same extensions into another directory

Question

guys. I\'ve got a problem I can\'t solve: I have a 2 folders I choose with folderBrowserDialog and tons of files in source directory I need to move to the target directory.

Answer 1

First get all the files with specified extension using Directory.GetFiles() and then iterate through each files in the list and move them to target directory.

//Assume user types .txt into textbox
string fileExtension = "*" + textbox1.Text;

string[] txtFiles = Directory.GetFiles("Source Path", fileExtension);

foreach (var item in txtFiles)
{
   File.Move(item, Path.Combine("Destination Directory", Path.GetFileName(item)));
}
