CurlEasy.SetOpt() string parameter bug

[masroore]

Even setting the parameters works and does not work. I think it should work interchangeably so and so.

//easy.UserAgent = "Do UserAgent"; // Works
easy.SetOpt(CurlOption.UserAgent, "Do UserAgent SetOpt"); // Does not work

//easy.Proxy = "xxx.xxx.xxx.xxx:21320"; // Works
easy.SetOpt(CurlOption.Proxy, "xxx.xxx.xxx.xxx:21320"); // Does not work

//easy.PostFields = postData; // Works :)
easy.SetOpt(CurlOption.PostFields, postData); // Does not work

//easy.Encoding = "gzip, deflate"; // Works
easy.SetOpt(CurlOption.Encoding, "gzip, deflate"); // Does not work

easy.FollowLocation = true; // Works or
easy.SetOpt(CurlOption.FollowLocation, true); // Works

At the time, please check yourself
