how to enter file path in c# selenium code example

Example 1: downloading in selenium

Selenium itself cannot verify file downloads, can click on download link
but can't go outside the browser and open the downloaded file 
Other tools need to be used for that Robot and AutoIT

Example 2: uploading in selenium

In order to upload file using selenium we need to locate the upload button 
in the DOM html. Then we do sendKeys by passing the path to the file. 

First, I locate the element which takes the path of the file(Choose file button) :
      WebElement input = driver.findElement(“id”); 
 And then I provide the path to the file using the sendKeys method :
      input.sendKeys(“/path/to/file” + Keys.ENTER);
