SEVERE: Servlet.service() for servlet [DoctorServlet] in context …我想使用 RegEx 将 url 分成两部分。我已将 xml 响应保存到数据表中，并使用 foreach 遍历每一行。当我使用 regEx 的数据表值时，只有 0 可用。当我使用数组索引 1 时，它给出以下异常。
System.IndexOutOfRangeException: Index was outside the bounds of the array.
以下是给出和异常。
foreach (DataRow row in ndt.Rows)
{
string imgurl =row["image1"].ToString();
String[] fimgurl = Regex.Split(imgurl, @"small/");
String simgurl = fimgurl[1];
}
下面它工作没有任何问题。
foreach (DataRow row in ndt.Rows)
{
//TextBox1.Text = row["ImagePath"].ToString();
string imgurl ="http://www.hotelbeds.com/giata/small/12/124356/124356a_hb_w_001.jpg";
String[] fimgurl = Regex.Split(imgurl, @"small/");
String simgurl = fimgurl[1];
}
我在我的数据表中保存了与字符串相同的 url。我找不到这有什么问题。任何人都可以帮我解决这个问题吗？
我需要优化我的代码.我有一些重复代码.但我想优化它.任何人都可以帮我优化我的代码.我怎样才能为此增加常用功能？
foreach (var item in hotellocation.GroupBy(x => x).ToDictionary(g => g.Key, g => g.Count()))
{
if (item.Key != "")
{
lstHotelLocation.Add(new HotelLocation()
{
Name = item.Key,
count = item.Value
});
}
}
//need to Apply to linq
foreach (var item in hoteltype.GroupBy(x => x).ToDictionary(g => g.Key, g => g.Count()))
{
if (item.Key != "")
{
lstHotelType.Add(new HotelTypeFilter()

Name = item.Key,
count = item.Value
