ASP.NET-016: save file dialog box in ASP. NET

ASP.NET-016: save file dialog box in ASP. NET
I wanted to use savediallog in asp.net to save the file. The result showed that the displayed mode dialog box or form is invalid when the application is not running in UserInteractive mode.

Use the following method in ASP. NET to save the file. In the following example, an excel file is saved.

Response. contentType = @ "application/x-xls"; Response. appendHeader ("Content-Disposition", "attachment; filename =" + @ "\ test.xls"); // write the Content to a file, for example, Response. flush (); // Response. writeFile ("file with content", true); // Response. write (parameter); Response. end ();

The code is simple.

In the preceding example, the running effect is as follows:


ContentType indicates the file type;
The AppendHeader is a prompt dialog box that allows you to choose to save the file;
The Response. WriteFile and Response. Write Methods Write existing files or content, such as strings and file streams, to the saved files as needed.

The file types are as follows:
