Public MustOverride ReadOnly Property DataRow As DataRow

public abstract DataRow DataRow { get; }

public:
virtual property DataRow^ DataRow {

abstract DataRow : DataRow with get

abstract function get DataRow () : DataRow

형식: System.Data.DataRow
DataRow 개체

설명

DataRow 속성은 열에 따른 현재 행의 값을 반환합니다.이 속성은 열을 기준으로 식별된 데이터를 반환합니다.열은 이름을 통해 식별되거나 다음 예제에서와 같이 인덱스 위치로 식별됩니다.DataRow[0]의 인덱스 식별자는 다음 예제 단원에 나와 있는 샘플 데이터 테이블을 사용하여 Table1의 Name 열에 대한 값을 반환합니다.

예제

다음 코드에는 테스트할 클래스와 메서드가 포함되어 있습니다.

using System;

namespace BankAccountNS
{
   public class BankAccount
   {
      private string m_customerName;
      private double m_balance;

      public BankAccount(string customerName, double balance)
      {
         m_customerName = customerName;
         m_balance = balance;
      }

      public double Balance
      { get { return m_balance; } }

      public void Debit(double amount)
      {
         if (amount < 0)
            throw new ArgumentOutOfRangeException("amount");
         m_balance -= amount;
      }
   }
}

Imports System

Namespace BankAccountNS
   Public Class BankAccount
      Private m_customerName As String
      Private m_balance As Double

      Public Sub New(ByVal customerName As String, ByVal balance As Double)
         m_customerName = customerName
         m_balance = balance
      End Sub

      Public ReadOnly Property Balance() As Double
         Get
            Return m_balance
         End Get
      End Property

        Public Sub Debit(ByVal amount As Double)
            If amount < 0 Then
                Throw New ArgumentOutOfRangeException("amount")
            End If
            m_balance -= amount
        End Sub
    End Class
End Namespace

아래의 테스트는 성공합니다.이 테스트에서는 다음과 같은 데이터의 Table1이 포함된 sample.mdb Access 데이터베이스를 사용합니다.

Name	Balance	양
Becky	100	25
John	70	60
Larry	75	71.25
Stephanie	159	158
Mr.Bryan Walton	11.99	11.22
