Selenium文件上传不起作用

Question

我试图通过Selenium进行简历上传。 我在页面上有2个按钮＆＃34;添加文件＆＃34;和＆＃34;上传＆＃34;

HTML：

<input type="file" name="uploadedfile" aria-labelledby="Uploader_0_label" accept=".doc, .docx, .pdf, .html, .htm, .wks, .txt" style="position: absolute; font-size: 2em; top: -3px; right: -3px; cursor: pointer; opacity: 0;" tabindex="-1" aria-disabled="false"/>


"<span id="Button_9_label" class="dijitReset dijitInline dijitButtonText" data-dojo-attach-point="containerNode">Upload</span>"

C＃Selenium：

 string newPath = filepath.Replace("\\\\","\\");
            Driver.FindElement(By.XPath("//input[@name='uploadedfile' and @type='file']")).SendKeys(newPath);
            Driver.FindElement(By.XPath("//span[text()='Upload']")).Click();
