定位页面上的select-option结构，尝试了以下几种方法，均没有生效：
//iw.FindElement(By.CssSelector("select#id > option[value=‘‘]")).Click();
//iw.FindElement(By.XPath("//select[@id=‘‘]/option[@value=‘‘]")).Click();
//iw.FindElements(By.TagName("option"))[index].Click();
最后通过以下这种方式，成功定位到了页面上的Select-option标签：
var selector = iw.FindElement(By.Id(""));
SelectElement select = new SelectElement(selector);
select.SelectByText("text");
Select对象可以通过option的value，text等属性对元素进行定位。
实际应用，如在SharePoint中创建site时，对于site template的选取和site path的选择：
public IWebDriver CreateSPSite(IWebDriver iw, string caUrl,string title,string template)
{
string createSitePage = caUrl + "/_admin/createsite.aspx";
iw.Navigate().GoToUrl(createSitePage);
WaitUntilPageLoadedID(iw, "ctl00_PlaceHolderMain_ctl02_RptControls_BtnCreateSite");
//Title.
iw.FindElement(By.Id("ctl00_PlaceHolderMain_idTitleDescSection_ctl01_TxtCreateSiteTitle")).SendKeys(title);
//Url.
var paths = iw.FindElement(By.Id("ctl00_PlaceHolderMain_ctl01_ctl04_DdlWildcardInclusion"));
SelectElement path = new SelectElement(paths);
path.SelectByText("/sites/");
WaitUntilPageLoadedID(iw, "ctl00_PlaceHolderMain_ctl01_ctl04_TxtSiteName");
iw.FindElement(By.Id("ctl00_PlaceHolderMain_ctl01_ctl04_TxtSiteName")).SendKeys(title);
switch (template)
{
case "ts":
break;
case "edi":
iw.FindElement(By.Id("ctl00_PlaceHolderMain_InputFormTemplatePickerControl_ctl00_ctl01_tabid1")).Click();
Thread.Sleep(1000);
WaitUntilPageLoadedID(iw, "ctl00_PlaceHolderMain_InputFormTemplatePickerControl_ctl00_ctl01_LbWebTemplate");
var selector = iw.FindElement(By.Id("ctl00_PlaceHolderMain_InputFormTemplatePickerControl_ctl00_ctl01_LbWebTemplate"));
SelectElement select = new SelectElement(selector);
select.SelectByText("eDiscovery Center");
break;
case "rc":
iw.FindElement(By.Id("ctl00_PlaceHolderMain_InputFormTemplatePickerControl_ctl00_ctl01_tabid1")).Click();
Thread.Sleep(1000);
WaitUntilPageLoadedID(iw, "ctl00_PlaceHolderMain_InputFormTemplatePickerControl_ctl00_ctl01_LbWebTemplate");
selector = iw.FindElement(By.Id("ctl00_PlaceHolderMain_InputFormTemplatePickerControl_ctl00_ctl01_LbWebTemplate"));
select = new SelectElement(selector);
select.SelectByText("Records Center");
break;
case "holdCenter":
iw.FindElement(By.Id("ctl00_PlaceHolderMain_InputFormTemplatePickerControl_ctl00_ctl01_tabid1")).Click();
Thread.Sleep(1000);
WaitUntilPageLoadedID(iw, "ctl00_PlaceHolderMain_InputFormTemplatePickerControl_ctl00_ctl01_LbWebTemplate");
selector = iw.FindElement(By.Id("ctl00_PlaceHolderMain_InputFormTemplatePickerControl_ctl00_ctl01_LbWebTemplate"));
select = new SelectElement(selector);
select.SelectByText("In-Place Hold Policy Center");
break;
}
iw.FindElement(By.Id("ctl00_PlaceHolderMain_idPrimaryAdministratorSection_ctl01_PickerOwner_upLevelDiv")).SendKeys(@"userName");
iw.FindElement(By.Id("ctl00_PlaceHolderMain_ctl02_RptControls_BtnCreateSite")).Click();
return iw;
}
对应在页面上的操作，第一段灰色部分的代码对如下标签进行了选择：
