我的C#代码有问题,我似乎无法使我的if语句正常工作,我认为由于某种原因它试图引用错误的代码部分。我检查了是否具有所有正确的引用以及所有正确的用途。我粘贴了下面的令人讨厌的代码:
FolderBrowserDialog dlg2 = new FolderBrowserDialog();
if (dlg2.ShowDialog() == DialogResult.OK)
//do whatever with dlg.SelectedPath
{
string searchPattern = "*";
DirectoryInfo source = new DirectoryInfo(dlg.SelectedPath);
DirectoryInfo target = new DirectoryInfo(dlg2.SelectedPath);
DirectoryInfo dir = new DirectoryInfo(dlg.SelectedPath);
FileInfo[] fi = dir.GetFiles("*", SearchOption.AllDirectories);
{
if (fi.LastWriteTime.Date == DateTime.Today.Date)
{
FileInfo[] sourceFiles = source.GetFiles(searchPattern, SearchOption.AllDirectories);
for (int i = 0; i < sourceFiles.Length; ++i)
File.Copy(sourceFiles[i].FullName, target.FullName + "\\" + sourceFiles[i].Name, true);
}
}
感谢您提供的任何帮助。
最佳答案
您想做的可能是这个吗?
FileInfo[] fis = dir.GetFiles("*", SearchOption.AllDirectories);
foreach (FileInfo fi in fis)
{
if (fi.LastWriteTime.Date == DateTime.Today.Date)
{
FileInfo[] sourceFiles = source.GetFiles(searchPattern, SearchOption.AllDirectories);
for (int i = 0; i < sourceFiles.Length; ++i)
File.Copy(sourceFiles[i].FullName, target.FullName + "\\" + sourceFiles[i].Name, true);
}
}
