如何从ASP.NET中的Web服务器搜索文件 [英] How to search a file from a Web server in ASP.NET

问题描述

大家好

我需要在托管我的网站的服务器中搜索pdf，doc，jpg等文件.我现在正在开发一个将在Intranet中托管和使用的网站.我现在在文件系统中工作.

我的实际问题是我不知道如何通过程序表示服务器，即不知道如何设置将文件上传到服务器的路径.

可以在上面的代码上帮助我吗..


我尝试了以下代码:-

hi all

i need to search files like, pdf,doc,jpg etc in a server where my site is hosted. i am now developing a website that is to be hosted and used in intranet. i am now working in file system.

my actual problem is i don''t know how to represent the server through program , that is, don''t know how to set the path to upload the files to server.

can any on help me with code for the above..


i tried the following code:-

protected void Button1_Click(object sender, EventArgs e)
   {
       string filename = TextBox1.Text;
       if (File.Exists(Server.MapPath("testit" + ( filename))))

      // if (File.Exists(Server.MapPath(filename)))
       {
           Response.Write("file exist");
       }
       else
       {
           Response.Write("no");
       }
   }

testit是我用来在IIS中托管我的网站的虚拟目录


在此先感谢.....

我上一个问题中的解决方案无法正常工作，请任何人帮助我

testit is the virtual directory that i made for hosting my website in IIS


thanks in advance.....

Solution in my previous question is not working any one plz help me

推荐答案

//string filename = TextBox1.Text;
 if (File.Exists(Server.MapPath("Image/untitled.png")))
     // if (File.Exists(Server.MapPath(filename)))

     Response.Write("file exist");
 else
 {
     Response.Write("no");
 }

这里"Image"是解决方案中的文件夹，"untitled.png"是此文件夹中的文件，我能够得到它.我认为在文本框中您没有获得正确的文件路径.

here "Image" is folder in solution and "untitled.png" is file in this folder and i am able to get this. I think in text box you are not getting correct file path.

您可以尝试以下代码在目录中搜索文件:

You can try this code to search files in the directory:

public static void disp(string source)
    {

        DirectoryInfo dr = new DirectoryInfo(source);

        DirectoryInfo dir = new DirectoryInfo(des);

        foreach (FileInfo fs in dr.GetFiles())
        {

            path = fs.Extension;

            switch (path)
            {

                case ".doc":

                    if (!Directory.Exists("DOC"))
                    {

                        dir.CreateSubdirectory("DOC");

                    }



                    Console.WriteLine("file" + fs.Name);

                   

                    break;

                case ".txt":

                    if (!Directory.Exists("txt"))
                    {

                        dir.CreateSubdirectory("txt");

                    }



                    Console.WriteLine("file" + fs.Name);

                    

                    break;

                case ".pdf":

                    if (!Directory.Exists("txt"))
                    {

                        dir.CreateSubdirectory("txt");

                    }



                    Console.WriteLine("file" + fs.Name);

                    

                    break;

            }



        }
    }
