我是sharepoint的新手。在ClientContext.ExecuteQuery.

之前检查Sharepoint站点连接的最快和最有效的方法是什么?
ClientContext ctx = new ClientContext(ConfigurationManager.AppSettings["sharepoint siteUrl"]);
float pageLoadTime = getPageLoadTime(ctx);
if(pageLoadTime > 0.5)
{
  MessageBox.Show("Sharepoint site is not available!");
  return;
}
//do very heavy query
....
ctx.ExecuteQuery();

如何在执行ClientContext.ExecuteQuery前检查Sharepoint的连通性

没有这样的标准方法。但是您可以像下面的代码

那样实现它
   using (ClientContext sourceContext = new ClientContext("Sharepoint Url"))
        {
            try
            {                    
                sourceContext.ExecuteQuery();
                List list = sourceContext.Web.Lists.GetByTitle("Test");
                ListItemCollection itemColl = list.GetItems(CamlQuery.CreateAllItemsQuery());
                sourceContext.Load(itemColl);
                sourceContext.ExecuteQuery();
            }                
            catch (System.Net.WebException ex)
            {
                if (ex.Message == "The remote server returned an error: (404) Not Found.")
                {
                    Console.WriteLine("SharePoint not available");
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }              
        }

因为"ExecuteQuery"是通过Client连接到SharePoint的方法。SVC WCF服务
