您是否已经调查了这些字符串？例如：

string s1 = "http://path/controller/action?id=" + id +"&accountNo=" + accountNo + "&hash=" + hash;
string s2 = "http://path/controller/action?id=2&accountNo=98989898&hash=65bbfbacba7435aed714ea3a4e9fc97ec92509b2c97d5";

bool are_equal = s1 == s2;

如果 are_equal 为false，则可能是变量（ id ，
accountNo ， hash ）不包含预期值。使用调试器继续研究。

If are_equal is false, then probably the variables (id, accountNo, hash) do not contain the expected values. Continue your research using the Debugger.
