InputFile.PostedFile.ContentLength测量单位

Question

请告诉我InputFile.PostedFile.ContentLength测量的单位.我需要确保文件小于500k.

谢谢.

Answer 1

计量单位=字节.

1 Kilobyte (kB) = 2ˆ10 Byte = 1024 Bytes

文件大小为15 KB的示例代码测试:

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."
}

在您的情况下,如您所希望的文件小于500 KB,您应该这样:

const int maxFileLength = 512000; // 500KB = 500 * 1024
