我如何將數據從一種表單發送到另一種類的功能

Question

我知道如何將數據從一種表單傳遞到另一種表單，但是我怎樣才能將數據從一種表單傳遞到類中。這是我的數據，我想通過從form1類問題：

string GrpID = "somevalue"; 
string DurationID = "somevalue";` 

我搜索了它，但我並沒有得到確切的答案了這一點。

class Question 
{ 
    string GroupID="here i want this value of GroupID,how can i get this"; 
    string DuraID="and here value of DurationID"; 

    // so that i can use them here like this 
    public IEnumerable<Question> GetQuestions(string topicId, int marks) 
    { 
     string sql = "select QID,Question,Opt1,Opt2,Opt3,Opt4,AnsOp,Marks from Questions where TopicID IN(" + 
        topicId + ") and Marks=" + marks.ToString(); 
     var cmd = new OleDbCommand(sql, new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=db1.mdb")); 
     var rs = cmd.ExecuteReader(); 

     if (rs != null) 
     { 
      while (rs.Read()) 
      { 
       yield return 
        new Question 
        { 
         Id = rs[0].ToString(), 
         Text = rs[1].ToString(), 
         Option1 = rs[2].ToString(), 
         Option2 = rs[3].ToString(), 
         Option3 = rs[4].ToString(), 
         Option4 = rs[5].ToString(), 
         AnswerOption = rs[6].ToString(), 
         Marks = marks 
        }; 
      } 
     } 
    } 
} 
public void Foo()//In this function Can i pass that `string[] conf` here? 
     { 
      var totQsn = Convert.ToInt16(conf[0]); // isn't this just the sum of everything else? 
      var mark1qsn = Convert.ToInt16(conf[3]); //this variable contains number of question to be display of mark 1 
      var mark2qsn = Convert.ToInt16(conf[4]); 
      var mark3Qsn = Convert.ToInt16(conf[5]); 
      var mark4Qsn = Convert.ToInt16(conf[6]); 

      var mark1questionSet = GetQuestions(topicId, 1).ToList(); 
      var mark2questionSet = GetQuestions(topicId, 2).ToList(); 
      }

添加一個方法到類：

class Question 
{ 

    public void SomeFunction(string grpId, string durationId) 
    { 
     ... 
    } 

} 

然後你可以從你的形式調用它：

questionInstance.SomeFunction("somevalue","somevalue");
