i wrote code but it make error for these line

 using (var image = Image.FromStream(sourcePath))

CompositingQuality.HighQuality;
SmoothingMode.HighQuality;
InterpolationMode.HighQualityBicubic;

Error17The type or namespace name 'ArrayList' could not be found (are you missing a using directive or an assembly reference?)

Error22The name 'SmoothingMode' does not exist in the current context

Error 23 The name 'InterpolationMode' does not exist in the current context

Error 21 The name 'CompositingQuality' does not exist in the current context

Error 20 'System.Web.UI.WebControls.Image' does not contain a definition for 'FromStream'

Error19'Image' is an ambiguous reference between 'System.Web.UI.WebControls.Image' and 'System.Drawing.Image

i should add name space for them what should i add?

thanks

Namespaces

using System.Collections;
using System.Drawing.Drawing2D;

and also change Image to System.Drawing.Image since it otherwise conflicts with Image control

System.Drawing.Image img = new System.Drawing.Image();
