网上说先压缩 然后在下载 可是他代码他多了 我有点不理解 我找到一个简单的代码 String the_rar;
RegistryKey the_Reg;
Object the_Obj;
String the_Info;
ProcessStartInfo the_StartInfo;
Process the_Process;
try
{
string dir = @"E:\nnewexam\upload";
the_Reg = Registry.ClassesRoot.OpenSubKey(@"Applications\WinRAR.exe\Shell\Open\Command");
the_Obj = the_Reg.GetValue("");
the_rar = the_Obj.ToString();
the_Reg.Close();
the_rar = the_rar.Substring(1, the_rar.Length - 7);
the_Info = " a " + " 052.rar " + " " +@"E:\nnewexam\upload\052";
the_StartInfo = new ProcessStartInfo();
the_StartInfo.FileName = the_rar;
the_StartInfo.Arguments = the_Info;
the_StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
the_StartInfo.WorkingDirectory = dir;//获取或设置要启动的进程的初始目录。
the_Process = new Process();
the_Process.StartInfo = the_StartInfo;
the_Process.Start();
Response.Write("压缩成功");
}
catch (Exception ex)
{
Response.Write(ex.ToString());
}
}
这个能压缩成功.但是不是我想要的结果.他压缩的内容包含了 虚拟目录的名 我想压缩的只包含upload 下的一个文件夹052的内容
RegistryKey the_Reg;
Object the_Obj;
String the_Info;
ProcessStartInfo the_StartInfo;
Process the_Process;
try
{
string dir = @"E:\nnewexam\upload";
the_Reg = Registry.ClassesRoot.OpenSubKey(@"Applications\WinRAR.exe\Shell\Open\Command");
the_Obj = the_Reg.GetValue("");
the_rar = the_Obj.ToString();
the_Reg.Close();
the_rar = the_rar.Substring(1, the_rar.Length - 7);
the_Info = " a " + " 052.rar " + " " +@"E:\nnewexam\upload\052";
the_StartInfo = new ProcessStartInfo();
the_StartInfo.FileName = the_rar;
the_StartInfo.Arguments = the_Info;
the_StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
the_StartInfo.WorkingDirectory = dir;//获取或设置要启动的进程的初始目录。
the_Process = new Process();
the_Process.StartInfo = the_StartInfo;
the_Process.Start();
Response.Write("压缩成功");
}
catch (Exception ex)
{
Response.Write(ex.ToString());
}
}

string dir = @"E:\nnewexam\upload";
改成
string dir = @"E:\nnewexam\upload\052";
试一试
很感激 对了 我现在还不太清楚:the_Info = " a " + " 052.rar " + " " +@"E:\nnewexam\upload\052"; 这句话 尤其是哪个"a" 为什么是A 还有就是the_StartInfo.WorkingDirectory = dir; 这话加不加都可以啊
