c# – 从.NET中的字符串获取url参数

使用返回NameValueCollection的System.Web.HttpUtility类的static ParseQueryString方法。

Uri myUri = new Uri("http://www.example.com?param1=good&param2=bad");

string param1 = HttpUtility.ParseQueryString(myUri.Query).Get("param1");

字典拼接url参数

var paramers = new Dictionary<string, string>();
            paramers.Add("PhoneNumbers", "13818354757");
            paramers.Add("SignName", "李工");
            paramers.Add("TemplateCode", "4215");
            paramers.Add("TemplateParam", "party");
            paramers.Add("AccessKeyId", "accessId");

            var imutableMap = new Dictionary<string, string>(paramers);           
            imutableMap.Add("SignatureMethod", "HMAC-SHA1");
            imutableMap.Add("SignatureVersion", "1.0");
            imutableMap.Add("SignatureNonce", Guid.NewGuid().ToString());
            imutableMap.Add("Action", "TEST");
 

            IDictionary<string, string> sortedDictionary = new SortedDictionary<string, string>(imutableMap, StringComparer.Ordinal);
            StringBuilder canonicalizedQueryString = new StringBuilder();
            foreach (var p in sortedDictionary)
            {
                canonicalizedQueryString
                    .Append("&")
                .Append(p.Key).Append("=")
                .Append(p.Value);
            }

            //AccessKeyId=accessId&Action=TEST&PhoneNumbers=13818354757&SignName=李工&SignatureMethod=HMAC-SHA1&SignatureNonce=1ba431e0-8328-46a6-a832-f5d711bff532&SignatureVersion=1.0&TemplateCode=4215&TemplateParam=party

            Console.WriteLine(canonicalizedQueryString.ToString().Substring(1));
