asp.net文件夹上传如何解决？
我在做的时候，可能需要上传文件夹，如何解决？
[解决办法]
把文件夾壓縮后再上傳，上傳后再解壓，下面是代碼，可能需要相應做修改
1.拷贝Rar.exe到程序根目录下
2.将要上传的文件打包成rar文件，注意我目前做的是该rar下直接包含图片文件，如1.rar下包含a.jpg,b.jpg等
3.aspx页面代码
<table border=0 cellPadding=4 cellSpacing=1 align="center" class=table-Kang>
<TR>
<TD colSpan=4 align="center"> <div class=biaoti>图片批量上传 </div> </TD>
</TR>
<tr>
<td align=right class=table-TitleBG>上传路径： </td>
<td align=left class=table-Sbg> <asp:FileUpload ID="myfile" runat="server" Width="400px" /> </td>
</tr>
<tr>
<td colspan=2 align=center class=table-TitleBG> <asp:Button ID="Button1" runat="server" Text="上 传" OnClick="Button1_Click" />
td>
</tr>
</table>
4.cs代码（注意：下面代码有设计到数据库方面的，要相应做修改）
protected void Button1_Click(object sender, EventArgs e)

if (myfile.HasFile)
{
if (myfile.PostedFile.FileName.EndsWith(".rar") ¦ ¦ myfile.PostedFile.FileName.EndsWith(".RAR"))

[解决办法]
压缩在上传吧
然后服务器上自动解压。
protected void Button1_Click(object sender, EventArgs e)
{
if (myfile.HasFile)
{
if (myfile.PostedFile.FileName.EndsWith(".rar") ¦ ¦ myfile.PostedFile.FileName.EndsWith(".RAR"))
#region//rar文件
{
string strListCode = Request.QueryString["sListCode"];
string strCategory = Request.QueryString["Category"];
//当前虚拟目录路径
string _strPicSavePath = "../";
string strGenerPath = GetPictureid();
string strDir = HttpContext.Current.Server.MapPath(_strPicSavePath + "Picture/" + strGenerPath + "/");//图片的保存目录
if (!Directory.Exists(strDir))
{
Directory.CreateDirectory(strDir);
}
string path = strDir + myfile.PostedFile.FileName.Substring(myfile.PostedFile.FileName.LastIndexOf("\\"));
myfile.PostedFile.SaveAs(path);
//Response.Write("文件上传成功：" + path);
//Response.End();
// 在此处放置用户代码以初始化页面
Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
p.StartInfo.FileName = "cmd.exe";
p.Close();
//解压Rar文件
// Response.Write(HttpContext.Current.Server.MapPath(_strPicSavePath));
string ServerDir = HttpContext.Current.Server.MapPath(_strPicSavePath); //@"C:\Program Files\WinRAR";//rar路径

string strFileNames = strFileName.Substring(1, strFileName.Length - 1);

//解压后文件夹绝对路径
string strCurPath = path + ".files" + "\\" + strFileName + "\\";
//解压后文件相对路径

if (strProdNames.Split('-').Length > 1)
{
strProdName = strProdNames.Split('-')[0];
strTitle = strProdNames;
}
else
{
strProdName = strProdNames;
strTitle = strProdNames;
}
string strSql = "insert into xpvProdPic(sProdCode,spath,sremark,spictureName,sPicTitle) values ('" + strProdName + "','" + strDataPath + "','','" + strName + "','"+strTitle+"' )";
DbHelperSQL.ExecuteSql(strSql);
}
string messageContent = "上传成功！";
StringHelp.WinAlert(Page, messageContent);
//Page.RegisterStartupScript("d", " <script language='javascript'>ReturnBefore('" + strListCode + "','" + strCategory + "'); </script>");
}

}
}

}
}
private string GetPictureid()
{
string id = System.DateTime.Now.Year.ToString() + System.DateTime.Now.Month.ToString().PadLeft(2, '0') + System.DateTime.Now.Day.ToString().PadLeft(2, '0') + System.DateTime.Now.Hour.ToString().PadLeft(2, '0') + System.DateTime.Now.Minute.ToString().PadLeft(2, '0') + System.DateTime.Now.Millisecond.ToString().PadLeft(3, '0');
//string id=id+
int i = new System.Random().Next(0, 5);
int k = new System.Random().Next(0, 9);
id = id + i.ToString() + k.ToString();
return id;
}
就像这样的代码。
