But not working in Selenium grid

[heyitsmesuraj]

Code:
private static IWebDriver _webdriver;
IAllowsFileDetection allowsDetection = _webdriver as IAllowsFileDetection;
allowsDetection.FileDetector = new LocalFileDetector();

var localDoc="C:\selenium_code\UITest\UIAutomationFramework\UIAutomation.Build\Documents\Test.txt
C:\selenium_code\UITest\UIAutomationFramework\UIAutomation.Build\Documents\Test 2.txt";
element = findElement(By.xpath("location");
element.sendKeys(localDoc);

Issue:
WebDriver.dll but was not handled in user code

Additional information: invalid argument: File not found : C:\selenium\Documents\Test.txt
