型または名前空間GlobalVarが見つかりませんでした

Question

これは私のコードであり、すべて問題はありませんが、GlobalVarには何も提案されていません。

[WebMethod(MessageName = "OpenAccount", Description = "This method is to add new account")] 
    [System.Xml.Serialization.XmlInclude(typeof(ContactResult))] 

    public ContactResult openaccount(String FullName, String Phone) 
    { 
     ContactResult cr = new ContactResult(); 
     **GlobalVar var = new GlobalVar();** 

     try 
     { 
      using (SqlConnection openconn = new SqlConnection(var.connectionstring)) 
      { 
       string save = "INSERT into AndroidContact (AndroidContactName,AndroidContactPhone) VALUES ('" + FullName + "' ,'" + Phone + "')"; 
       using (SqlCommand query = new SqlCommand(save)) 
       { 
        query.Connection = openconn; 
        query.Parameters.Add("@AndroidContactName", SqlDbType.NVarChar, 50).Value = FullName; 
        query.Parameters.Add("@AndroidContactPhone", SqlDbType.NVarChar, 50).Value = Phone; 

        openconn.Open(); 
        query.ExecuteNonQuery(); 
        openconn.Close(); 
       } 
      } 

      cr.ErrorID = 0; 
      cr.ErrorMessage = "Contact Added"; 
      return cr; 
     } 
      catch (Exception ex){ 

       cr.ErrorID = 1; 
       cr.ErrorMessage = ex.Message; 
       return cr; 
     } 
    } 
} 

}

おかげで愛するが、私はそのように地雷を固定：

パブリッククラスWebService1：System.Web.Services.WebService {

[WebMethod(MessageName = "OpenAccount", Description = "This method is to add new account")] 
    [System.Xml.Serialization.XmlInclude(typeof(ContactResult))] 

    public ContactResult openaccount(String FullName, String Phone) 
    { 
     ContactResult cr = new ContactResult(); 
     SqlConnection Connection = new SqlConnection(); 
     try 
     { 
      Connection.ConnectionString = ConfigurationManager.ConnectionStrings["webConnectionString"].ToString(); 
      Connection.Open(); 
      SqlCommand save = new SqlCommand ("INSERT into AndroidContact (AndroidContactName,AndroidContactPhone) VALUES ('" + FullName + "' ,'" + Phone + "')",Connection); 

      save.ExecuteNonQuery(); 

      cr.ErrorID = 0; 
      cr.ErrorMessage = "Contact Added"; 
      return cr; 
     } 
     catch (Exception ex) 
     { 

      cr.ErrorID = 1; 
      cr.ErrorMessage = ex.Message; 
      return cr; 
     } 
    } 
}
