至于我可以告诉以下两个示例在功能方面是相同的。
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
那么为什么我在点之后只得到 C# 中的实例方法（见下文）
z = Example.Examples.One.
在 VB.net 中
Dim z = Example.Examples.One.
我也得到Examples
到底是怎么回事？为什么有区别？
