推荐答案

这不是上载，而是指定文件的位置.您无需担心上传和保存.如果您只想将该文件保存到其他位置，请使用以下代码:

That is not uploading, but specifying the location of the file. You don''t need to bother about Uploading and Saving. If you just want to save that file to another location, use the following code:

string FileToCopy = null;
string NewCopy = null;

FileToCopy = "C:\\Users\\Owner\\Documents\\test.txt";
NewCopy = "C:\\Users\\Owner\\Documents\\NewTest.txt";


if (System.IO.File.Exists(FileToCopy) == true) {
    System.IO.File.Copy(FileToCopy, NewCopy);
    Interaction.MsgBox("File Copied");

}

您需要使用 System.IO;

you need to import system.io as

将system.io导入为

using System.IO;

Initialize the original path to FileToCopy variable and specify the Intended location to save the file in NewCopy variable.

在保存文件之前，您必须重命名文件名.

如果您上载的文件名类似于file.pdf，则在尝试保存时拆分文件名，直到找到字符``.''，然后在文件名旁边附加一些文本(例如_new)，然后再次连接文件名和扩展名，然后将其保存为file_new .pdf.

如果您使用的是fileUpload，请尝试这样

You have to rename the file name before saving it.

If your uploaded filename is like file.pdf , when trying to save split the file name till you find character ''.'' and append some text next to file name (like _new) and concatenate filename and extension again and save it like file_new.pdf.

If you are using fileUpload then try like this

if (fileUpload1.HasFile)
{
string strPath = Server.MapPath("~");
strPath = strPath + "\\Resumes\\" + txtUsername.Text;
Directory.CreateDirectory(strPath);
strPath = strPath + "\\";
fileUpload1.SaveAs(strPath + fileUpload1.FileName);
}
