C implements the method of copying files in a folder to another folder

This article illustrates how C # implements copying files from a folder to another folder. Share it for your reference. The details are as follows:

private void CopyDir(string srcPath, string aimPath)
{
 　 try
 　 {
 　 //  Check whether the destination directory ends with a directory dividing character. If not, add 
 　 if (aimPath[aimPath.Length - 1] != System.IO.Path.DirectorySeparatorChar)
 　 {
 　 aimPath += System.IO.Path.DirectorySeparatorChar;
 　 }
 　 //  Determine whether the target directory exists. If it does not exist, create a new one 
 　 if (!System.IO.Directory.Exists(aimPath))
 　 {
 　 System.IO.Directory.CreateDirectory(aimPath);
 　 }
 　 //  Get the file list of the source directory, which contains the file and directory path 1 Array of numbers 
 　 //  If you point to copy Use the following method for files below the target file without directories 
 　 // string[] fileList = Directory.GetFiles ( srcPath ); 
 　 string[] fileList = System.IO.Directory.GetFileSystemEntries(srcPath);
 　 //  Traverse all files and directories 
 　 foreach (string file in fileList)
 　 {
 　 //  Treat it as a directory first. If this directory exists, recursive Copy Files under this directory 
 　 if(System.IO.Directory.Exists(file))
 　 {
 　 CopyDir(file, aimPath + System.IO.Path.GetFileName(file));
 　 }
 　 //  Otherwise directly Copy Documents 
 　 else
 　 {
 　 System.IO.File.Copy(file, aimPath + System.IO.Path.GetFileName(file),true);
 　 }
 　 }
 　 }
 　 catch(Exception e)
 　 {
 　 throw;
 　 }
 　 }
}

I hope this article is helpful to everyone's C # programming.
