1这是最简单的方法
DirectoryInfo di = new DirectoryInfo(string Path);
di.Delete(true);
注：path是你要删除的非空目录；
true：你要删除里面所有的文件，包括文件夹和子文件夹
2
/// <summary>
/// 删除非空文件夹
/// </summary>
/// <param name="path">要删除的文件夹目录</param>
void DeleteDirectory(string path)
{
DirectoryInfo dir = new DirectoryInfo(path);
if (dir.Exists)
{
DirectoryInfo[] childs = dir.GetDirectories();
foreach (DirectoryInfo child in childs)
{
child.Delete(true);
}
dir.Delete(true);
}
}
3 递归方法：(这是删除文件的方法)
private staticv oid DeleteDirectory(File tmpFile) {
if (!tmpFile.exists()) {
System.out.println("file is not exist!");
return;
}
if (tmpFile.isDirectory()) {
File[] fileList = tmpFile.listFiles();
for (int i =0; i < fileList.length; i++) {
if (fileList[i].isDirectory()) {
DeleteDirectorys(fileList[i]);s
}
}
}
}
