현재 거래일에 3 일을 더해야합니다

Question

나는 이미 ArrayList에 현재 거래일에 3 일을 추가해야하는 버튼이 있습니다.

어떻게 수행하나요? 당신은 더 이상 코드가 필요하면

private void btnCheckCleared_Click(object sender, EventArgs e) 
{ 
    foreach (Transaction item in tranArray) 
    { 
     if (What goes here?) 
     { 
      DateTime.Today.AddDays(3).ToLongDateString(); 
     } 
    } 
} 

은 알려 주시기 바랍니다 다음과 같이

코드입니다. 당신은 그런 일이 필요

namespace TEXT TEXT TEXT 

{ 
    public class Transaction 
    { 
     //data hiding (blackbox) 
     //visible only to class itself 
     //fields (variables) 
     //4 member variables (instantiate object) 
     private decimal decAmount; 
     private DateTime dteTransactionDate; 
     private string strCheckNumber; 
     private string strPayee; 
     private string strTypeTrans; 
     public bool CheckCleared; 

     public decimal Amount 
     { 
      get 
      { 
       return decAmount; 
      } 
      set 
      { 
       decAmount = value; 
      } 
     } 

     public string CheckNumber 
     { 
      get 
      { 
       return strCheckNumber; 
      } 
      set 
      { 
       strCheckNumber = value; 
      } 
     } 

     public string Payee 
     { 
      get 
      { 
       return strPayee; 
      } 
      set 
      { 
       strPayee = value; 
      } 
     } 

     public DateTime TransactionDate 
     { 
      get 
      { 
       return dteTransactionDate; 
      } 
      set 
      { 
       dteTransactionDate = value; 
      } 
     } 


     public TransactionType TypeTrans; 

     //constructor 
     public Transaction(string payee, decimal amount, TransactionType typeTrans, DateTime transactionDate) 
     { 
      this.Payee = payee; //assignment operator = 
      this.Amount = amount; //this is to qualify 
      this.TypeTrans = typeTrans; 
      this.TransactionDate = transactionDate; 
     } 

     public Transaction(string payee, decimal amount, TransactionType typeTrans, DateTime transactionDate, string checkNumber) 
     { 
      this.Payee = payee; //assignment operator = 
      this.Amount = amount; //this is to qualify 
      this.CheckNumber = checkNumber; 
      this.TypeTrans = typeTrans; 
      this.TransactionDate = transactionDate; 
     } 

     //public Transaction() 

     public override string ToString() 
     { 
      return this.TransactionDate.ToShortDateString() + " " + this.Amount.ToString("C") + "\t" + this.TypeTrans; 
     } 
    } 
}

:

그래서 여기 내 Transaction.cs 코드

private void btnCheckCleared_Click(object sender, EventArgs e) 
{ 
    foreach (Transaction item in tranArray) 
    { 
     if (/*Whatever your condition looks like*/) 
     { 
      item.TransactionDate = item.TransactionDate.AddDays(3); 
     } 
    } 
} 

AddDays가 지정된 DateTime을 수정하지 않습니다를하지만 새로운DateTime 반환, 그것이 할당 된 이유입니다. item.TransactionDate
