seleniumRC +VSTS+ Nunit 腳本元素找不到解決方法

//selenium.WaitForPageToLoad("30000");

 //selenium.Click("id=MainContent_sPa28_Siuma1_確認_0");

 

            Thread.Sleep(5000);//因下面一句经常报错特加此句
            if (selenium.IsElementPresent("id=MainContent_sPa28_Siuma1_確認_0"))
            {

                selenium.Click("id=MainContent_sPa28_Siuma1_確認_0");

            }
