获取错误为“不是虚拟虚拟路径”同时保存图像 [英] Getting error as "Is not a vaild virtual path" while saving the image

问题描述

 <  表格    id   =  form1    runat   =  server >  
 <   div  >  
 
 < ;   asp：按钮    ID   =  Button1    runat   =  server    onclick   =  Button1_Click   文字  =  按钮    /  < span class =code-keyword>>  
 
 <   br     /  >  
 <   asp：FileUpload     ID   =  filUpload    runat   =  server    /  >  
 
 <   / div  >  
 <   /表格 >  

 protected void Button1_Click（object sender，EventArgs e）
 {
 string savepath =; 
 var directoryInfo = new DirectoryInfo（C：\\Users \\viki \\Documents \\Visual Studio 2008 \\WebSites\\WebSite3）; 
 if（directoryInfo.Exists）
 {
 string a =NewFolder1; 
 directoryInfo.CreateSubdirectory（a）; 
 savepath = a; 
} 
 
 
 if（filUpload.PostedFile！= null）
 {
 //SaveFile(filUpload.PostedFile）; 
 
 HttpFileCollection colFiles = HttpContext.Current.Request.Files; 
 HttpPostedFile objCurrentFile = colFiles.Get（0）; 
 
 
 string fileNameWithoutExtension = Path.GetFileNameWithoutExtension（objCurrentFile.FileName）; 
 string fileExtension = Path.GetExtension（objCurrentFile.FileName）; 
 
 filUpload.PostedFile.SaveAs（Server.MapPath（directoryInfo +\\+ savepath）+ fileNameWithoutExtension + fileExtension）; 
 
} 
} 

我收到保存为line.it的错误说该路径不是虚拟路径。



帮我完成此文件上传通过创建一个新的动态文件夹来处理。



提前谢谢..

解决方案

在网络应用程序中你无法访问以在本地计算机上保存文件。您只能将文件保存在Web应用程序的子文件夹中。这是有效路径的示例：〜\ MyFolder并且表示来自我的Web应用程序根目录的文件夹MyFoloder。

< blockquote>

  if （filUpload.PostedFile！=  null ）
 {
 
  string  fileNameWithoutExtension = Path.GetFileNameWithoutExtension（filUpload.PostedFile.FileName）; 
  string  fileExtension = Path.GetExtension（filUpload.PostedFile.FileName）; 
 filUpload.PostedFile.SaveAs（Server.MapPath（savepath +   / + fileNameWithoutExtension + fileExtension））; 
 
} 

工作正常..感谢大家，你的想法让它解决了。再次感谢你。

<form id="form1" runat="server">
    <div>

        <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />

        <br />
        <asp:FileUpload ID="filUpload" runat="server" />

    </div>
    </form>

protected void Button1_Click(object sender, EventArgs e)
        {
        string savepath="";
        var directoryInfo = new DirectoryInfo("C:\\Users\\viki\\Documents\\Visual Studio 2008\\WebSites\\WebSite3");
        if (directoryInfo.Exists)
            {
            string a = "NewFolder1";
            directoryInfo.CreateSubdirectory(a);
            savepath = a;
            }

        
        if (filUpload.PostedFile != null)
            {
            //SaveFile(filUpload.PostedFile);

            HttpFileCollection colFiles = HttpContext.Current.Request.Files;
            HttpPostedFile objCurrentFile = colFiles.Get(0);
           
            
            string fileNameWithoutExtension = Path.GetFileNameWithoutExtension(objCurrentFile.FileName);
            string fileExtension = Path.GetExtension(objCurrentFile.FileName);
            
            filUpload.PostedFile.SaveAs(Server.MapPath(directoryInfo+"\\"+savepath)+ fileNameWithoutExtension + fileExtension);

            }
        }

I'm getting the error in the save as line.it's saying that the path is not a vaild virtual path.

Help me to complete this file upload process by creating a new dynamic folder.

Thanks in advance..

解决方案

In web application you have not access to save the file on your local computer. You can save the files only in subfolders of your web application. This is an example of valid path: "~\MyFolder" and means the folder ""MyFoloder" from my web application root.

if (filUpload.PostedFile != null)
                {
                
string fileNameWithoutExtension = Path.GetFileNameWithoutExtension(filUpload.PostedFile.FileName);
string fileExtension = Path.GetExtension(filUpload.PostedFile.FileName);
filUpload.PostedFile.SaveAs(Server.MapPath(savepath + "/" + fileNameWithoutExtension + fileExtension));
                
                }

It's working fine.. Thanks to everyone,your ideas made it to solve.Thank you Once again.
