با استفاده از این مقاله میتونید مشخصات صاحب دامنه و اطلاعات کامل مربوط به دامنه رو در Asp.Net بدست بیارید

سلام دوستان

با استفاده از این مقاله میتونید مشخصات صاحب دامین و غیره رو بدست بیارید

یا چک کنید دامنه موجود است یا خیر

در پروژه یک کلاسی وجود داره با نام Whois.cs که تمام این کارها را انجام خواهد داد

بقیه کدها در فرم

Whois.Whois w=new Whois.Whois(); w.LookupComplete += w_LookupComplete; w.Lookup(TextBox1.Text);

موفق و پیروز باشید
