详细说就是用C#调用方法：
public static void PutFile(string bucket, string key, string fname)
{
var policy = new PutPolicy(bucket, 3600);
string upToken = policy.Token();
PutExtra extra = new PutExtra();
IOClient client = new IOClient();
PutRet ret= client.PutFile(upToken, key, fname, extra);
//MessageBox.Show(ret.Hash.ToString(),ret.key);
}
时，需要通过URL传值获取Token值，Qiniu.dll里有没有传一个URL值返回Token的方法？
