私が知る限り、次の2つの例は機能的には同じです。
C#
namespace ConsoleApplication4
{
class Program
{
static void Main(string[] args)
{
var x = new Example(12);
var y = new Example(34);
var z = Example.Examples.One;
}
}
class Example
{
public static class Examples
{
public static readonly Example Zero = new Example(0);
public static readonly Example One = new Example(1);
}
public readonly Double Value;
public Example(Double Value)
{
this.Value = Value;
}
public static Example Add(Example x, Example y)
{
return new Example(x.Value + y.Value);
}
}
}
VB.net
Option Strict On
Module Module1
Sub Main()
Dim x=New Example(12)
Dim y = New Example(34)
Dim z= Example.Examples.One
End Sub
End Module
Public Class Example
Public Class Examples
Public Shared ReadOnly Zero As Example
Public Shared ReadOnly One As Example
Public Shared ReadOnly Two As Example
Public Shared ReadOnly MinusOne As Example
Shared Sub new()
Zero=New Example(0)
One= New Example(1)
Two = New Example(2)
MinusOne = New Example(-1)
End Sub
End Class
Public ReadOnly Value As Double
Public Sub New(Value As Double)
Me.Value=Value
End Sub
Public Shared Function Add(x As Example,y As Example) As Example
Return New Example(x.Value+y.Value)
End Function
End Class
では、なぜドットの後にC#のインスタンスメソッドのみを取得するのですか(以下を参照)
z = Example.Examples.One.
およびVB.netで
Dim z = Example.Examples.One.
私も取得しますExamples
何が起こっている?なぜ違いがあるのですか?
