Tengo una sección de administración de sitio web en la que estoy ocupado trabajando, que tiene 4 controles FileUpload para fines específicos. Necesito saber que, cuando uso el método Server.MapPath()
dentro de los métodos SaveAs()
del control FileUpload, ¿se podrá usar en el servidor web una vez que haya cargado el sitio web? Por lo que yo sé, SaveAs()
requiere una ruta absoluta, es por eso que hacen corresponder un camino con Server.MapPath()
Carga de archivos usando Server.MapPath() y FileUpload.SaveAs()
if (fuLogo.HasFile) //My FileUpload Control : Checking if a file has been allocated to the control
{
int counter = 0; //This counter Is used to ensure that no files are overwritten.
string[] fileBreak = fuLogo.FileName.Split(new char[] { '.' });
logo = Server.MapPath("../Images/Logos/" + fileBreak[0] + counter.ToString()+ "." + fileBreak[1]); // This is the part Im wondering about. Will this still function the way it should on the webserver after upload?
if (fileBreak[1].ToUpper() == "GIF" || fileBreak[1].ToUpper() == "PNG")
{
while (System.IO.File.Exists(logo))
{
counter++; //Here the counter is put into action
logo = Server.MapPath("../Images/Logos/" + fileBreak[0] + counter.ToString() + "." + fileBreak[1]);
}
}
else
{
cvValidation.ErrorMessage = "This site does not support any other image format than .Png or .Gif . Please save your image in one of these file formats then try again.";
cvValidation.IsValid = false;
}
if (fuLogo.PostedFile.ContentLength > 409600) //File must be 400kb or smaller
{
cvValidation.ErrorMessage = "Please use a picture with a size less than 400 kb";
cvValidation.IsValid = false;
}
else
{
if (fuLogo.HasFile && cvValidation.IsValid)
{
fuLogo.SaveAs(logo); //Save the logo if file exists and Validation didn't fail. The path for the logo was created by the Server.MapPath() method.
}
}
}
else
{
logo = "N/A";
}
Ah, y Logo se declara una variable de cadena en el ámbito global – Eon
