如何保存上传的文件？ c＃mvc [英] How save uploaded file? c# mvc

问题描述

我想上传一个图像文件到项目的文件夹，但我有一个错误在我的catch：
找不到路径的一部分'C：\ project \uploads\logotipos\11111\ '。

我做错了什么？我想保存我的客户端上传的那个图片在那个文件夹中...那个文件夹是存在的...如果我给folder_exists3放置一个断点，它显示我真正的值！

我的代码是：

  try 
 {
 var fileName = dados.cod_cliente; 
 bool folder_exists = Directory.Exists（Server.MapPath（〜/ uploads））; 
 if（！folder_exists）
 Directory.CreateDirectory（Server.MapPath（〜/ uploads））; 
 bool folder_exists2 = Directory.Exists（Server.MapPath（〜/ uploads / logo））; 
 if（！folder_exists2）
 Directory.CreateDirectory（Server.MapPath（〜/ uploads / logo））; 
 bool folder_exists3 = Directory.Exists（Server.MapPath（〜/ uploads / logo /+ fileName））; 
 if（！folder_exists3）
 Directory.CreateDirectory（Server.MapPath（〜/ uploads / logo /+ fileName））; 
 
 file.SaveAs（Server.MapPath（〜/ uploads / logo /+ fileName +/））; 
 
 catch（例外e）
 {
} 
  

有人知道我做错了吗？

谢谢：）

解决方案试试这个：

$ $ $ $ $ $ c $ string> targetFolder = ）;
字符串targetPath = Path.Combine（targetFolder，yourFileName）;
file.SaveAs（targetPath）;

I want upload an image file to project's folder but I have an error in my catch: Could not find a part of the path 'C:\project\uploads\logotipos\11111\'.

What am I do wrong? I want save that image uploaded by my client in that folder... that folder exists... ah if I put a breakpoint for folder_exists3 that shows me a true value!

My code is:

try
{
    var fileName = dados.cod_cliente;
    bool folder_exists = Directory.Exists(Server.MapPath("~/uploads"));
    if(!folder_exists)
        Directory.CreateDirectory(Server.MapPath("~/uploads"));
    bool folder_exists2 = Directory.Exists(Server.MapPath("~/uploads/logo"));
    if(!folder_exists2)
        Directory.CreateDirectory(Server.MapPath("~/uploads/logo"));
    bool folder_exists3 = Directory.Exists(Server.MapPath("~/uploads/logo/" + fileName));
    if(!folder_exists3)
        Directory.CreateDirectory(Server.MapPath("~/uploads/logo/"+fileName));

    file.SaveAs(Server.MapPath("~/uploads/logo/" + fileName+"/"));
}
catch(Exception e)
{
}

Someone knows what I'm do wrong?

Thank you :)

解决方案

Try this:

string targetFolder = HttpContext.Current.Server.MapPath("~/uploads/logo");
string targetPath = Path.Combine(targetFolder, yourFileName);
file.SaveAs(targetPath);
