Hi,
you can read textfile from client machine, only by fileupload control.
Client will upload their textfile, and then you can read textfile as below.
FileUpload fup = fu1;
if (fup.HasFile)
{
StreamReader reader = new StreamReader(fup.FileContent);
do
{
string textLine = reader.ReadLine();
}
while (reader.Peek() != -1);
reader.Close();
}
Hope it helps you.
Thanks.
