ASP:NET File Upload check if exist
Hello I have this routine to upload files with ASP.NET:
String savePath = @"C:\inetpub\wwwroot\esp\d
if (FileUpload1_1.HasFile)
{
string FileExtention = System.IO.Path.GetExtensio
if (FileExtention == ".pdf")
{
String fileName = FileUpload1_1.FileName;
savePath += fileName;
FileUpload1_1.SaveAs(saveP
pdfdocumento1_1.Text = "All fine";
}
else
{
pdfdocumento1_1.Text = "Is not .pdf. ";
}
Now what I need to add and wehre to check if the new upload already exist on the dir to avoid overwrtie?
Thank you
String savePath = @"C:\inetpub\wwwroot\esp\d

Try this:
As mrjoltcola suggested, you can check the existance of file at:
==========================
String savePath = @"C:\inetpub\wwwroot\esp\d
if (FileUpload1_1.HasFile)
{
string FileExtention = System.IO.Path.GetExtensio
if (FileExtention == ".pdf")
{
String fileName = FileUpload1_1.FileName;
savePath += fileName;
if(System.IO.File.Exists(s
throw new Exception(...); //File already exists
FileUpload1_1.SaveAs(saveP
pdfdocumento1_1.Text = "All fine";
}
else
{
pdfdocumento1_1.Text = "Is not .pdf. ";
}
