C#:逻辑实现改进以及性能

您可以在冒号前获取文本并在a中使用它switch.获取冒号后的文本,因此您不必为此重复代码:

string detail = GetDetail();
int index = detail.IndexOf(':');
if (index != -1) {
  string before = detail.Substring(0, index);
  string after = detail.Substring(index + 1).Trim();
  switch (before) {
    case "stackoverflow": detailItem.Stackoverflow = after; break;
    case "google": detailItem.Google = after; break;
    case "facebook": detailItem.Facebook = after; break;
    case "twitter": detailItem.Twitter = after; break;
  }
}
