Please modify the above parameters according to your own specific situation.


(3) Find the Upload.ashx in the Ashx folder
Find this code upload. SaveAs (Path.Combine) (context. Server.MapPath ("Upload"), name);
The absolute path saved here. Context. Server.MapPath ("upload") means that the project upload.ashx the current path to the upload folder under which name is the filename
We're going to build a folder in the directory upload to store uploaded files.
Change upload. SaveAs (Path.Combine) (context. Server.MapPath (".. /.. /upload "), name);
The uploaded file is saved in the Upload folder.

(4) Set configuration file Web.config
Add under </system.web> node
<location path= "Information Package/ashx/upload.ashx" >
<system.web>
</system.web>
</location>
where maxrequestlength= "3100" is the maximum limit of 3M timeout for executiontimeout= "300"

(5) When used, add the following code:
<div style= "Float:left" ><input type= "text" id= "Path"/></div>
<div style= "Float:left" ><div id= "Spanbuttonplaceholder" ></div></div>

The upload control is done here. Click to run, have you learned it.

(MVC is similar to this one, and it's no longer elaborate.) Note that in MVC <input type= "text" id= "path"/>id cannot be the path keyword

and the content folder under MVC. If you want to use a relative path, it's best to go back to the content folder, and then look down.
