Accepted answer
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.
