Asp. NET to TXT file related operation (read, write, Save) _ Practical skills

ASP. NET read TXT file (Notepad) content:

 using System; 
Using System.Collections; 
Using System.Configuration; 
Using System.Data; 
Using System.Web; 
Using System.Web.Security; 
Using System.Web.UI; 
Using System.Web.UI.HtmlControls; 
Using System.Web.UI.WebControls; 
Using System.Web.UI.WebControls.WebParts; 
Using System.IO; Get TXT file stream namespace test {public partial class Text:System.Web.UI.Page {protected void Page_Load (object send 
  Er, EventArgs e) {Response.Write (Getinteridlist ("Asp.txt")); 
   //Read TXT file content public string getinteridlist (String strfile) {string strout; 
   Strout = ""; if (! File.exists (System.Web.HttpContext.Current.Server.MapPath (strfile))) {} else {StreamReader sr = new 
    StreamReader (System.Web.HttpContext.Current.Server.MapPath (strfile), System.Text.Encoding.Default); String input = Sr. 
    ReadToEnd (); Sr. 
    Close (); 
   Strout = input; 
  return strout; } 
 } 
}

Read TXT file content is to get the file stream, remember to reference using System.IO;.

Asp. NET Write TXT file (Notepad):

String txtpath = Server.MapPath ("~\\public\\attinfo\\") + "Test.txt"; 
StreamWriter sw = new StreamWriter (Txtpath, False, System.Text.Encoding.Default); 
Sw. WriteLine ("Hello World"); 
Sw. WriteLine (""); Output empty line 
SW. WriteLine ("ASP. NET programming-cloud-dwelling community! "); 
Sw. Close ();

Note: If write Notepad does not need to wrap, you can use write, you need to wrap, you can use WriteLine.

Asp. NET Save txt file (Notepad):

public void ProcessRequest (HttpContext context)
  {context

   . Response.Clear ();
   Context. Response.Buffer = true;
   Server.URLEncode prevents saved file names from garbled context
   . Response.AddHeader ("Content-disposition", "attachment;filename=" + context. Server.URLEncode ("Consumption detail" + string.) Format ("{0:YYYYMMDDHHMMSS}", System.DateTime.Now) + ". txt"); 
   Context. Response.ContentType = "Text/plain"; 
   String message = "Hello World";
   If the exported file is to be wrapped, use environment.newline message
   = + "Hello World" + Environment.NewLine;
   Context. Response.Write (message);
   Stops the execution context of the page  
   . Response.End (); 
  }

Note 3 points:

1. Save file name garbled problem: using Server.URLEncode encoding

Line wrapping in 2.txt file: Environment.NewLine

3. Calls can be js:window.location.href= "Download.ashx" or window.open ("Download.ashx")

The above is about TXT file related operation, if my article is helpful to you, just order a praise.
