InputFile.PostedFile.ContentLength Units of measurement
Please can you tell me the units measured by InputFile.PostedFile.ContentLength . I need to make sure the file开发者_StackOverflow社区 is less than 500k.
Thanks.
Unit of measurement = Byte.
1 Kilobyte (kB) = 2ˆ10 Byte = 1024 Bytes
Sample code testing for a file size of 15 KB:
const int maxFileLength = 15360; // 15KB = 1024 * 15
if(PictureFile.PostedFile.ContentLength > maxFileLength)
{
MyResult.Text = String.Format("Your post has a size of {0:#,##0} bytes which
exceeded the limit of {0:#,##0} bytes. Please upload a smaller file.",
PictureFile.ContentLength, maxFileLength);
}
else
{
// Save the file here
MyResult.Text = "Thank you for posting."
}
In your case, as you want the file to be less than 500 KB, you should have this:
const int maxFileLength = 512000; // 500KB = 500 * 1024
It's bytes.

HttpPostedFile.ContentLength
Gets the size of an uploaded file, in bytes.
When i am uploading a template file of more than 1 mb its geting loaded for long time.my code is as below----

string destinationImage = Server.MapPath("/master/" + emp_id.ToString().Trim() + "/Images/");
string destination1 = Server.MapPath("/master/" + emp_id.ToString().Trim() + "/Images/");
string imgFilename, fileExt = String.Empty;
Response.Write(fileTemplateimage.PostedFile.ContentLength+"<br/>");
Response.Write(fileTemplateimage.FileBytes.Length);
Response.End();
if (fileTemplateimage.PostedFile.ContentLength > 0 && fileTemplateimage.FileBytes.Length <= 1048576)
{
System.Drawing.Image uploadImage = System.Drawing.Image.FromStream(fileTemplateimage.PostedFile.InputStream);
float uploadImagewidth = uploadImage.PhysicalDimension.Width;
float uploadImageheight = uploadImage.PhysicalDimension.Height;
else
{
Page.ClientScript.RegisterStartupScript(this.GetType(), "failure", "alert('अपलोड फ़ाइल आकार 1 एमबी से अधिक नहीं होना चाहिए.');", true);
divhide.Style.Add("display", "block");
divUploadpanel.Style.Add("display", "block");
