上傳文件我有一個網站管理部分,我很忙,有4個FileUpload控件用於特定目的。我需要知道的是,當我在FileUpload控件的SaveAs()
方法中使用Server.MapPath()
方法時,在我上傳網站後它仍然可以在Web服務器上使用嗎?據我所知,SaveAs()
需要一個絕對路徑,這就是爲什麼我地圖Server.MapPath()
使用Server.MapPath()和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";
}
