[WebMethod]
public static void SendEmail(string name,string phone,string emailaddress,string interest,string comments)
{
    var control = LoadControl("~/Shared/Controls/EmailTemplate_PartnerWithUs.ascx");

    StringBuilder sb = new StringBuilder();
    StringWriter sw = new StringWriter(sb);
    Html32TextWriter htw = new Html32TextWriter(sw);

    control.RenderControl(htw);

    sb.Replace("%name%",name);
    sb.Replace("%phone%",phone);
    sb.Replace("%emailaddress%",emailaddress);
    sb.Replace("%interest%",interest);
    sb.Replace("%comments%",comments);
    EmailUtility.SendEmailMessage(SettingsManager.GetContactRecipientEmails(),"CoyleHomeBuyers.com Partner Form",sb.ToString());
}

我得到的错误是：

An object reference is required for the non-static field,method,or property 'System.Web.UI.TemplateControl.LoadControl(string)'

有没有办法在WebMethod中加载此控件？
