示例1: foreach
string sourceDir = @"c:\current";
string backupDir = @"c:\archives\2008";
try
{
string[] picList = Directory.GetFiles(sourceDir, "*.jpg");
string[] txtList = Directory.GetFiles(sourceDir, "*.txt");
// Copy picture files.
foreach (string f in picList)
{
// Remove path from the file name.
string fName = f.Substring(sourceDir.Length + 1);
// Use the Path.Combine method to safely append the file name to the path.
// Will overwrite if the destination file already exists.
File.Copy(Path.Combine(sourceDir, fName), Path.Combine(backupDir, fName), true);
}
// Copy text files.
foreach (string f in txtList)
{
// Remove path from the file name.
string fName = f.Substring(sourceDir.Length + 1);
try
{
