在使用Selenium上传之前，如何获取文件的大小

Question

I've been trying for days to do this..

I want to simply get the size of the file before it is uploaded.

something like this:

IWebElement element = driver.FindElement(By.Id("FileUpload"));
string fileSizeInKB = element.GetAttribute("files[0].size");

or this:

IWebElement element = driver.FindElement(By.Id("FileUpload"));
string fileSizeInKB = element.GetAttribute("files")[0].size;

neither of these ways works so I'm asking how I could archive something similar?

You can use the System.IO.File namespace

byte[] buffer = System.IO.File.ReadAllBytes(@"yourfilename");
int size = buffer.Length;

Update

IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
string title = (string)js.ExecuteScript("Your JavaScript Here");
