C Sharp(C#)中如何删除文件(文件夹)
C Sharp(C#)中如何删除文件(文件夹)
直接删除:
using System.IO;
...
string filePath = @"D:\...\xxx.xxx";
if (File.Exists(filePath))
{
File.Delete(filePath);
}
else
{
Console.WriteLine("file not exist.");
Console.ReadLine();
}
删除到回收站:
using System.Runtime.InteropServices;
namespace CSharp
{
class Program
{
private const int FO_DELETE = 3;
private const int FOF_ALLOWUNDO = 0x40;
private const int FOF_NOCONFIRMATION = 0x0010;
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto, Pack = 1)]
public struct SHFILEOPSTRUCT
{
public IntPtr hwnd;
[MarshalAs(UnmanagedType.U4)]
public int wFunc;
public string pfrom;
public string pTo;
public short fFlags;
[MarshalAs(UnmanagedType.Bool)]
public bool fAnyOperationsAborted;
public IntPtr hNameMappings;
public string lpszProgressTitle;
}
[DllImport("shell32.dll", CharSet = CharSet.Auto)]
static extern int SHFileOperation(ref SHFILEOPSTRUCT FileOp);
static void Main(string[] args)
{
string filePath = @"D:\...\xxx.xxx";
if (File.Exists(filePath))
{
SHFILEOPSTRUCT fileop = new SHFILEOPSTRUCT();
fileop.wFunc = FO_DELETE;
fileop.pfrom = filePath + '\0' + '\0';
fileop.fFlags = FOF_ALLOWUNDO | FOF_NOCONFIRMATION;
SHFileOperation(ref fileop);
Console.WriteLine("delete ok");
Console.ReadLine();
}
else
{
Console.WriteLine("file not exist.");
Console.ReadLine();
}
}
}
}

用 Java 解密 C# 加密的数据(DES)
[原文地址：http://yidinghe.cnblogs.com/articles/449212.html]
今天碰上一件令我头大的事情。我们的系统要和一个外部系统进行通讯，传输方式是采用 DES 算法对消息进行加密，再用 BASE64 编码。不过对方系统是用 C# 写的。平台不一样，于是我和对面的老兄先测试一下加密解密。 ......
