而我们通过这个公用类来对cookies操作就显得容易了许多
public void Write()
{
//不用域名，通用性
VCommons.Http.CookieHelper.Write("test", "name", "bobo123");
//加域名，ＩＰ地址形式
VCommons.Http.CookieHelper.WriteWithDomain("test2", "nameByDomain"
, "bobo>Domain>IP", "127.0.0.1");
//加域名，可以用localhost进行本地调试
VCommons.Http.CookieHelper.WriteWithDomain("test3", "nameByDomain"
, "bobo>localhost", "localhost");
}
public void Clear()
{
//清除cookies名称为test的所有cookies元素
VCommons.Http.CookieHelper.Remove("test");
//将指定名称下的指定键值设置成空
VCommons.Http.CookieHelper.Write("test", "name", string.Empty);
VCommons.Http.CookieHelper.Write("test2", "nameByDomain", string.Empty);
VCommons.Http.CookieHelper.Write("test3", "nameByDomain", string.Empty);
}
