What is fileupload control in ASP.NET in English and Hindi

 

Fileupload control in ASP.NET in English

In ASP.NET, the FileUpload control is used to upload files from the client machine to the server. The FileUpload control provides a way to browse for a file and select it for upload.

Here is an example of how to use the FileUpload control in ASP.NET:
 
In this example, we have a FileUpload control with an ID of "myFileUpload". The runat="server" attribute tells ASP.NET that this control should be processed on the server. We also have a Button control with an ID of "uploadButton" that will be used to initiate the file upload.
When the user clicks the "uploadButton", the following code will execute:
 
In this code, we first check if the user has selected a file to upload by checking the HasFile property of the FileUpload control. If a file has been selected, we get the name of the file using the GetFileName method of the Path class.
We then use the SaveAs method of the FileUpload control to save the file to a specified location on the server. In this example, we are saving the file to a folder named "uploads" in the root directory of the web application.
Finally, we update a label control named "statusLabel" with a message indicating whether the file was uploaded successfully or if the user needs to select a file.
The FileUpload control is a useful tool for allowing users to upload files to a web application. It can be used to upload images, documents, and other types of files. However, it is important to validate the file types and sizes to prevent security issues and ensure that the application can handle large files without causing performance problems.
 

Fileupload control in ASP.NET in Hindi

ASP.NET me, FileUpload control ka use client machine se server par files upload karne ke liye kiya jata hai. FileUpload control browse karne ka ek option provide karta hai jisse user apne machine se files select karke upload kar sakta hai.
Yahan ek FileUpload control ka example hai:
 
Is example me, humne FileUpload control ka use kiya hai jiska ID "myFileUpload" hai. runat="server" attribute batata hai ki ye control server par process kiya jana chahiye. Humne ek Button control bhi add kiya hai jiska ID "uploadButton" hai, jisse file upload initiate kiya ja sake.
Jab user "uploadButton" par click karta hai, to ye code execute hota hai:
 
Is code me, humne pahle check kiya hai ki user ne koi file select kiya hai ya nahi. Iske liye humne HasFile property ka use kiya hai jo bata dega ki koi file select kiya gaya hai ya nahi. Agar file select kiya gaya hai, to hum GetFileName method ka use karke file ka naam nikalte hain.
Phir hum SaveAs method ka use karke file ko server par save karte hain. Is example me, hum file ko "uploads" folder ke andar save kar rahe hain jo ki web application ke root directory me hai.
Akhir me, hum ek label control ka use karke status update karte hain jisme bataya jata hai ki file upload ho gaya hai ya nahi.
FileUpload control, users ko web application me files upload karne ke liye ek useful tool provide karta hai. Isse images, documents aur dusre file types upload kiye ja sakte hain. Lekin iska important hai ki file types aur sizes ko validate kiya jaye taki security issues se bacha ja sake aur performance problems na ho.
