How to convert any URL to Image in ASP.Net

Refer the below sample code for your reference.

C#

protected void Page_Load(object sender, EventArgs e) { System.Net.WebClient webClient = new System.Net.WebClient(); string url = "https://static.flickr.com/66/199481236_dc98b5abb3_s.jpg"; byte[] bytes = webClient.DownloadData(url); string fileName = (url.Split('/')[url.Split('/').Length - 1]).Split('.')[0]; Response.ContentType = "image/png"; Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName); Response.BinaryWrite(bytes); Response.End(); }

VB.Net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load Dim webClient As System.Net.WebClient = New System.Net.WebClient() Dim url As String = "https://static.flickr.com/66/199481236_dc98b5abb3_s.jpg" Dim bytes As Byte() = webClient.DownloadData(url) Dim fileName As String = (url.Split("/"c)(url.Split("/"c).Length - 1)).Split("."c)(0) Response.ContentType = "image/png" Response.AppendHeader("Content-Disposition", "attachment; filename=" & fileName) Response.BinaryWrite(bytes) Response.[End]() End Sub
