Yes.. string userid = Session[UserID].ToString(); FileInfo[] files = di.GetFiles(userid + * SearchOption.TopDirectoryOnly); foreach (FileInfo item in files) { if (item.Name.Split('_')[0].ToString() == userid) //if (item.Name.ToString() == sagar_abc.jpg) { if(File.Exists(Path.Combine(filepath item.Name))) File.Delete(Path.Combine(filepath item.Name)); } } You can call me by my name so no Sir here :)

Thanks Satish Sir for your reply i hava one doubt that 1) FileInfo[] files = di.GetFiles(*.jpg SearchOption.TopDirectoryOnly); //suppose user added any extenstion image i.e. .png & .gif so how i will write FileInfo[] files 2) if (item.Name.ToString() == sagar_abc.jpg) // suppose in my project temp folder suppose sagar_abc.jpg & sagar_cbd.gif images present so my problem is that how i collect that images according userid i.e. sagar then that images deleted Sir can we write this in your code imagepathcollection = allimagepath.Where(img => img.StartWith(userId)); //you will get all images which starts with the userid specified. can we used search string method to collrect images according to initial name of string i.e. sagar ? pleas reply me

string filepath = C:\temp; DirectoryInfo di = new DirectoryInfo(filepath); FileInfo[] files = di.GetFiles(*.jpg SearchOption.TopDirectoryOnly); foreach (FileInfo item in files) { //if (item.Name.Split('_')[0].ToString() == sagar) if (item.Name.ToString() == sagar_abc.jpg) { if(File.Exists(Path.Combine(filepath item.Name))) File.Delete(Path.Combine(filepath item.Name)); } }

Hi Are you getting the all image path collection regardless of userid. if so imagepathcollection = allimagepath.Where(img => img.StartWith(userId)); you will get all images which starts with the userid specified. then delete the files as you did.
