如何高效更新ASP.NET MVC中长尾词的QueryString拼接？

本文共计590个文字，预计阅读时间需要3分钟。

“将NameValueCollection对象转换为查询字符串的后台方法如下：

csharppublic static string ToQueryString(NameValueCollection nvc){ StringBuilder sb=new StringBuilder(); foreach (var key in nvc.AllKeys) { string value=nvc[key]; // 使用EscapeDataString对特殊字符进行uri编码 sb.Append(key).Append('=').Append(value); } return sb.ToString();}

后台

public static string ToQueryString(NameValueCollection nvc) { StringBuilder sb = new StringBuilder(); foreach(var key in nvc.AllKeys) { string value = nvc[key]; //EscapeDataString就是对特殊字符进行uri编码 sb.Append(key).Append("=") .Append(Uri.EscapeDataString(value)).Append("&"); } return sb.ToString().Trim(‘&‘);//去掉最后一个多余的& } public static string RemoveQueryString(NameValueCollection nvc,string name) { NameValueCollection newNVC = new NameValueCollection(nvc); newNVC.Remove(name); return ToQueryString(newNVC); } public static string UpdateQueryString(NameValueCollection nvc, string name,string value) { NameValueCollection newNVC = new NameValueCollection(nvc); if(newNVC.AllKeys.Contains(name)) { newNVC[name] = value; } else { newNVC.Add(name, value); } return ToQueryString(newNVC); }
